Introduction
In international medical historiography, the authorship of the closed method, a surgical procedure for the treatment of compound fractures of the limbs that became widely accepted and practiced during the interwar period, has been essentially attributed to the surgeons Hiram Winnet Orr (West Newton, PA, 1877–Rochester, MN, 1956) and Josep Trueta Raspall (Barcelona, 1897–1977). Orr was the pioneer who, in the early 1920s, after his experience with the American Expeditionary Force in France during the First World War (1914–18), established a method consisting of a precise sequence of steps: Friedrich technique (opening and debridement of the wound); disinfection with Dakin-Carrel solution; filling with Vaseline gauze; immobilisation of the limb with plaster of Paris over a gauze bandage.Footnote 1 However, many of his colleagues in the United States and Great Britain failed to endorse the new procedure. The Spanish Civil War (1936–39) would hasten its recognition, both due to its massive application and to the introduction of certain changes, especially the indication of applying it in the very first hours after the fracture had occurred. French doctors observing this treatment in hundreds of Republican wounded combattants who crossed the border in the retreat following the occupation of Barcelona by General Franco’s forces in February 1939 called it, with a certain contempt, ‘Spanish method’Footnote 2.
The successful experiences of the Spanish Civil War would mainly get international projection through Great Britain. Exiled in this country, Josep Trueta’s work was quickly endorsed by the prestigious Oxford surgeon G.R. Girdlestone and published in journals such as The Lancet Footnote 3 and the British Medical Journal. Footnote 4 Trueta also disseminated his findings in the classic treatise Treatment of War Wounds and Fractures: With Special Reference to the Closed Method as Used in the War in Spain,Footnote 5 whose American edition was prefaced by Orr himself.Footnote 6 He set out his own five-point ‘programme’ for the treatment of open fractures: early surgical intervention; wound cleansing; wound excision; application of drainage; immobilisation with plaster.Footnote 7 The Spanish surgeon traced the ultimate origin of this programme to his long experience in the treatment of industrial accidents dating back to the late 1920s, although the cases he presented in his publications in English were those wounded in Barcelona’s air raids and those evacuated from various war fronts to his service at the General Hospital of Catalonia. The British army’s adoption of Trueta’s programme during the Second World War led the ‘Orr method’ to being called ‘Orr-Trueta’.Footnote 8 Since the 1970s, accounts sympathetic with or emanating from Catalan nationalism have referred to it simply as ‘Trueta’s method’ or claimed its ‘undisputable’ paternity for the Barcelona surgeon.Footnote 9
The central role played by Trueta and the Spanish Civil War cannot hide the fact that the story of the closed method has remained an essentially Anglo-Saxon narrative centred on the two great world conflicts of the twentieth century. The surgical traditions and the conflicts of other countries, with their corresponding actors, have been left out of a picture they could nevertheless enrich and substantially modify.Footnote 10 Their consideration could also provide valuable insights on general questions dealt with in the history of science in recent decades, such as the relation between wars and scientific ‘progress’Footnote 11 or the global circulation of knowledge and practices.Footnote 12 We will engage with all these issues through a study of the Spanish army surgeon Manuel Bastos (Zaragoza 1887–Barcelona 1973) (Figure 1) and of his treatment of compound fractures in an early phase of his career, especially during his service at Morocco’s Rif War (1921–27). Bastos has received considerable attention in Spain, mostly, but not exclusively,Footnote 13 from military medical historians and doctors, who have championed the label ‘Orr-Bastos-Trueta method’Footnote 14 as a means to acknowledge his contributions. However, most analyses of his work have been superficial. It has been claimed without sufficient documentary evidence that Bastos already employed ‘a distant precedent’Footnote 15 of the occlusive technique in the early campaigns in Morocco in the 1910s before properly applying it when the Rif War broke out in July 1921.Footnote 16 The treatment of ‘a large number of open fractures in this conflict, mostly caused by bullets’Footnote 17 would have allowed Bastos to improve ‘the closed method extraordinarily’Footnote 18 on the basis of the principle that ‘rigorous immobilisation is a fundamental requisite […] and most especially after the initial surgical examination of the wound or the necessary debridement’.Footnote 19 In the years that followed the Rif War and until the outbreak of the Spanish Civil War, Bastos would have reached ‘among us [in Spain] the maximum perfection’Footnote 20 in the application of the procedure.

Public domain.

Despite these claims, it is still unclear today, on the one hand, what the exact technique used by Bastos to treat the wounded in Morocco was, when he began to use it, how many fractures and of what type he treated, and where he disseminated his findings. These shortcomings have been justified on the grounds of ‘the scarcity of Bastos’ writings on the Spanish colonial wars’.Footnote 21 Although not a prolific and data-rich author, he nevertheless did publish regularly and provide statistical evidence. On the other hand, historiography has not sorted out whether Bastos developed his own autonomous version of the closed method or relied on the contributions of other Spanish and foreign surgeons, Orr in particular. This is a key question for whose analysis all historians have hitherto relied on his autobiography De las guerras coloniales a la Guerra Civil. Memorias de un cirujano [From the colonial wars to the Spanish Civil War. Memories of a surgeon] (henceforth, Memorias). Bastos claimed there categorically that
this [closed] method - which I might well call my method, though I don’t - was adopted by all Spanish surgeons on my side [Republican] in the hecatomb of our Civil War. It was later taken to England by Dr. Trueta and spread all over the world under the name of ‘Spanish method of occlusive cure’. But its authorship [Bastos’] has been recognised and proclaimed by the said doctor [Trueta] in his well-publicised publications, as well as by all those who have dealt with this aspect of war surgery. I do not intend to show off, just to leave a record of what happened.Footnote 22
A superb piece of writing, Bastos’ Memorias are, however (as this type of historical source in general is), a much belated account of events and, as such, liable not only to accidental and deliberate omissions, but also to reinterpretations resulting from both the author’s own biographical evolution and the new historical and social circumstances from which the text is written.Footnote 23 Regarding the latter, Bastos published his memoirs during General Francisco Franco’s dictatorship, which, despite the relative liberalisation of the late 1960s, still precluded or restricted mentions to certain actors, institutions, and events of decisive importance in his professional career. Similarly, international medicine had undergone profound transformations since the days preceding the First World War, making it very hard to acknowledge the weight that certain ideas and practices, as well as individuals, groups, or countries had had in earlier periods. Based on these and previous considerations, the main aim of this article is to provide a more solid and situated reconstruction of Manuel Bastos’ early contributions to the development of the closed method, especially his practice during the Rif War. For this purpose, it will be necessary to explore how exchanges between military and civilian, wartime and peacetime surgical practices took place in Spain. It will also be necessary to unearth neglected trans-Atlantic circulations between Spain, France, Latin America, and the United States during the interwar period, embodied mainly in the figure of the Argentinian surgeon Pedro Chutró. Ultimately, this paper is an attempt to re-centreFootnote 24 the story of the closed method.
Bones of soldiers, bones of children
The early orientation of Manuel Bastos towards orthopaedic surgery and traumatology – the latter speciality, as Roger Cooter has shown, only slowly emerging from general surgery between the late 19th century and the 1930sFootnote 25 – took place in a dual professional context. On the one hand, Bastos joined the Army Medical Corps just months after graduating in Medicine in Zaragoza in June 1907. A son of a military officer, he knew that army physicians were the largest group of state doctors in Spain, while civilian practitioners suffered from administrative atomisation and financial insecurity except for the case of the Marine Health Corps (Sanidad Exterior).Footnote 26 Following the compulsory one-year special training at the Army Medical Academy in Madrid, Bastos was assigned to various posts in which he gained his first practical experience as a surgeon. The most important were those in the Spanish Protectorate in Morocco, a tiny enclave adjacent to the Strait of Gibraltar which Spain had begun to occupy some years before its official establishment in November 1912 (Figure 2). Bastos took part in the military operations that followed a surprise attack by Riffian (Amazigh/Berber populations of the Rif mountain range) insurgents near Melilla in September 1909 that killed 150 soldiers and wounded another 600.Footnote 27 Over 30,000 Spanish troops were shipped across the Strait to retake the lost territory, though the vast majority of military actions in the Protectorate prior to 1921 involved much smaller contingents. As the Riffians, at this stage, were only equipped with Mauser rifles, lacking artillery, gunshot wounds and fractures were neither frequent nor too serious.Footnote 28 Bastos grew increasingly familiar with their treatment and evacuation, as for example in a clash near the iron mines in the Melilla region, in which he assisted two hundred wounded on the spot and took them over to that town.Footnote 29

He may also have learnt innovations in the management of compound fractures that senior colleagues were pioneering. Captain doctor Sebastián Lazo, director of a civil-military dispensary near Melilla, advocated for ‘the method that has come to be called Japanese [as developed in the Russo-Japanese War of 1904-05]’, which had achieved a ‘very low mortality rate in our wounded soldiers’. This method consisted of avoiding any cleansing of the wound with antiseptic solutions and any examination beyond the indispensable to confirm the existence of a fracture; to disinfect the wound orifices with iodine, dress it with aseptic gauze, cover the area with a simple aseptic bandage, and ensure that the patient stood in ‘complete rest’.Footnote 30 More specifically, in relation to limb fractures, whose frequency had been on the rise since the days of the Second Boer War (1899–1902) due to developments in weapons and projectiles,Footnote 31 captain doctor Rafael Ramírez-Rivas, also stationed in the Melilla area, pointed to the ‘paradoxical fact that more and better consolidations are achieved in cases in which these [forearm] fractures are open and the surgeon can therefore directly act upon the focus of the fracture, as often happens in war surgery’.Footnote 32 Ramírez-Rivas claimed he knew of a hundred cases in which the wounded ‘have not lost their limbs, the [open] fracture consolidating with greater perfection than in cases of simple fracture’, and re-joined the ranks ‘to finish their duty for the country […] preserving intact, or just slightly diminished, the forearm’s pronation and supination’.Footnote 33
In addition to technical advances, it became clear to Bastos how important it was to ensure a good evacuation from the front line so that further damage was prevented, especially in the abrupt mountainous orography of northern Morocco. During his second assignment in the Protectorate in 1913, he operated two hundred men wounded in a battle at Laucien (19 km east of Tetouan). Two days later, he transported them to the military hospital of that city and
continued to assist them personally […] until the doctor who had to replace me in the battalion showed up. I was then free to return to Spain, but I did so at the head of an expedition of wounded who were taken by ambulance [from Tetouan] to Ceuta, from there by boat to Algeciras, and from there by hospital train to Madrid. They were those who had received my first aid at the front. I was thus able to supervise them in the most delicate stage of their recovery, and I sincerely believe that this was of great benefit to them. All the more so because I was able to continue to care for many of them until they were completely cured.Footnote 34
Bastos became a fracture specialist in a civilian context too. In the early twentieth century, Spanish army doctors were allowed to combine this work with positions in the general health system and administration, in the university, or in private medicine. Their action also reached well beyond military personnel through the provision of outpatient and hospital care to their families, to the general population of certain small towns or peripheral regions, and in case of major epidemics.Footnote 35 This militarization of Spanish medicine and public health just mirrored that of Spanish politics and society. On returning in 1910 from his first assignment in Morocco, Bastos began his civilian trajectory at the Instituto de Terapéutica Operatoria [Surgical Therapy Institute] or Instituto Rubio in Madrid. This was a private teaching and assistance centre founded by Federico Rubio Galí, a renowned physician, hygienist, and politician who decisively contributed to the introduction of many health innovations in Spain.Footnote 36 Rubio’s activities were inspired by and connected with the ‘regenerationist’ drive that since the end of the nineteenth century struggled to modernise the Spanish administration, economy, and education under the guidance of organisations such as the Institución Libre de Enseñanza [Free Teaching Institution].Footnote 37 Bastos entered the Instituto’s department of Orthopaedic Surgery, directed by Adolfo López-Durán (1877–1930). Although mentioned several times in his Memorias, these failed to reflect the professional and scientific weight of a relation that would last for two decades. López-Durán had achieved a solid position in Madrid’s medical milieu under the protection of the surgeon and politician Alejandro San Martín.Footnote 38 In addition to the Instituto Rubio, he also worked as a consultant at the Royal Palace, head of a service at the Provincial Hospital, and inspector at the National Maritime Sanatorium of Oza (Galicia) for children with tuberculosis. His main specialisation was precisely the surgical treatment of bone lesions caused by that disease, then rampant among Spain’ working class, as occurred in most Western countries. López-Durán published many articles and several monographs, some of which circulated abroad.Footnote 39 He presented his research mostly at national conferences such as the 3rd Spanish Congress on Tuberculosis held in San Sebastian in 1912 or the 2nd National Congress of Medicine in Seville in 1924. With the experience gained in two years of work with López-Durán, Bastos prepared his 1912 doctoral thesis Anatomía y mecánica de la bóveda plantar y sus deformaciones [Anatomy and mechanics of the arch of the foot and its deformities]. This study aimed to provide a solid structural basis for the handling of bone lesions caused by trauma or disease.
After his second stay in Morocco, Bastos took back his research with López-Durán, though this time with a clinical-surgical approach, probably influenced by his military experience. The main outcome was a joint monograph with the revealing title La práctica del tratamiento de las fracturas de los miembros [Praxis of the treatment of limb fractures] (1915), which constituted Bastos’ debut into fracture therapy. It was based on patients assisted at the Instituto Rubio and the Clínica Militar de Emergencia [Military Emergency Hospital] (an antenna of the suburban Military Hospital of Madrid-Carabanchel in the centre of the Spanish capital). A chapter of this book, ‘Treatment of fractures of the upper section of the humerus’, was published in advance as a journal article by the end of 1914. The authors did not explain why they chose these fractures, and not others, for an independent publication, but we believe this resulted from the convergence between López-Durán’s interest in the increasing number of closed fractures of that bone in tuberculosis patients he treated in Madrid and Galicia, and Bastos’ interest in the increasing number of open fractures of the arm in soldiers wounded in Morocco. In their article-chapter, López-Durán and Bastos presented a ‘containment device’ (Figure 3) of their own as the most appropriate means of treating closed humerus fractures in children. Given the characteristic ‘restlessness’ of these young patients and the difficulty of keeping them bedridden for long periods of time, the best way to ensure immobility was to use a plaster bandage. This was prepared by placing a layer of cotton wool over the chest, shoulder and affected limb of the child and then covering it with ‘circular wraps of plaster bandages […] which have been dipped in water heavily charged with alum, squeezing them well so that they set quickly, and in such a way that they encircle the chest, shoulder and arm up to the wrist’.Footnote 40 This device was the first move towards the practice of the closed method we have been able to identify in Bastos’ career.

In fact, López-Durán and Bastos considered plaster bandages to be the most useful treatment for humerus fractures in adults too. Unlike splints, which ‘immobilise, but do not achieve a well-reduced containment of the fragments’, therefore being regarded mainly useful for first aid cures and evacuation, plaster bandages ‘can hold the fragments better […], provided they are used […] in those cases in which the reduction has been achieved in a perfect way’.Footnote 41 Quoting the French surgeon Just-Lucas Championnière, head of service at the Hôtel-Dieu in Paris and author of the influential Précis du traitement des fractures par le massage et la mobilisation (1910), they concluded that
immobility not only attenuates or suppresses pain and inflammation, but ‘is the best way to promote the repair of fractures’. Indeed, it has been proven that strictly immobilised fractures heal earlier and better than those allowed some mobility, even if very little. […] In our opinion, this method should be used for all fractures of the upper limb […].Footnote 42
The making of Orr’s and Bastos’ methods
López-Durán and Bastos’ decision to advance the publication of that chapter of his book was also influenced by the recent outbreak of the First World War in July 1914. In addition to over 20 million dead, this conflict resulted in hundreds of thousands of cases of open gunshot wounds caused by machine guns, mines, artillery shells, and airplane bombs.Footnote 43 In all belligerent armies, doctors struggled to improve the management of these patients. Hiram Winnet Orr did it in successive assignments in England, Wales, and France from May 1917 to June 1919, where he began to use the plaster bandages that would later become a distinctive feature of the closed method. At his first post in the Whitechurch Hospital of Cardiff, he observed ‘the unhappy results of treatment and the long delay in healing that followed many cases of open fractures resulting from gunshot wounds’,Footnote 44 concluding that successive wound dressings were a negative factor in the evolution of patients. Orr was later transferred to Base Hospital No. 8 in Savenay, France, which served as an evacuation centre for all US Army base hospitals in that country, sending ‘large numbers of wounded […] to the United States’.Footnote 45 These wounded, up to 5,000 a month, were distributed at the moment of arrival in separate wards for femur fractures (192 beds), arm fractures (256 beds), leg fractures (128 beds), knee joint injuries (34 beds), or amputations (320 beds).Footnote 46 They were then prepared for the long transatlantic trip with splints so that the damage caused by the ships’ rocking was neutralised. Only when the supply of splints ran out and despite opposition from colleagues and chiefs, Orr ‘obtained permission to send home patients with open fractures encased in plaster, even though suppurating wounds were present’.Footnote 47 The goal was then to prevent further damage in compound fractures, not to heal them, so
large windows were cut over all open wounds and over Patellae, heels, etc. Casts were not split. Plaster of Paris was used especially for fractures of the femur, leg, and upper arm. In femur and upper arm cases, body casts were employed. From September to December [1918] about one thousand plaster casts per month were put on and practically all sent to the United States. No complications as to casts were reported and in general the patients were found to have travelled safely and comfortably.Footnote 48
Orr’s case seems to confirm Leo van Bergen’s claim that medical innovations are not as frequent in wartime as often implied, due, among other things, to the priority of military doctors being the return of the wounded to the ranks rather than their cure, and to the difficulty of carrying out a long-term follow-up.Footnote 49 It was only after the war, with his return to civilian practice in Nebraska, that the American surgeon made plaster bandages the basis for a treatment of open fractures of the limb that prevented the development of chronic osteomyelitis of the type he frequently observed in industrial accidents’ victims. Orr first presented his ‘closed method’ in two articles of February 1923 and November 1924. In the former, published in The Nebraska State Medical Journal, he gave a full, systematic description of the technique. Building on a general ‘principle of rest’, Orr prescribed the ‘restoration of the injured parts to normal relationship’ and the wounded limb’s ‘immobilization and protection in correct position until complete healing has occurred’.Footnote 50 In between these two steps, the surgeon should proceed ‘to “saucerizing” both soft tissue and bone as suggested by [Alexis] Carrell, [Pedro] Chutró, and others’; to cleaning up the wound as thoroughly as possible; so that finally ‘the saucer-like opening of both soft tissues and bone is gently packed with sterile Vaseline and gauze’.Footnote 51 Once this was done, the whole area should be covered with dry sterile gauze and the entire limb ‘encased in a well-fitting cast of sufficient extent to completely immobilize the infected part. Casts are not split, and no windows are cut. If there is no indication on account of a rise of temperature for a change in dressing, this dressing is left in place for ten days to two or three weeks’.Footnote 52 Orr claimed to have applied this method to 25–30 patients ‘with much better results than formerly and without danger’.Footnote 53 His second, 1924, article contained only a short description of the technique, though it reached a much larger public thanks to its being published in the Journal of the American Medical Association and in collaboration with this prestigious society’s vice-president, James Edwin Thomson. Orr and Thomson explained that
in the employment of our technic for the treatment of compound fracture wounds, which we have fully described elsewhere [1923 article], the wound is cleaned up or debrided, filled lightly with a petrolatum gauze pack, and is covered under the cast with a dry, sterile pad. […] Unless there is marked rise in temperature, the wound remains untouched for from two to six weeks, at which time a window is made over the wound, and the first dressing is removed. […] Our experience in treating fractures by this method is that the period of healing is only a little longer than that of simple fractures, and the ultimate function of the limb is much more satisfactory than by other methods we have employed.Footnote 54
The closed method would be the object of new articles by Orr in 1927 and 1928 and of the 1929 treatise Osteomyelitis and Compound Fractures and Other Infected Wounds Footnote 55. In the Anglo-Saxon world, they enjoyed a wide circulation, though with mild success. In other regions, the situation was more complex. In the case of Spain, which did not participate as a belligerent in the First World War, army surgeons had missed the experience with fracture treatment of their European and US colleagues. It has been assumed that this gap was only closed with the outbreak of the Spanish Civil War in 1936. However, the so-called Rif War (1921–27) provided an earlier chance for catching up with world war innovations. This conflict, still badly known today, brought a significant escalation in Spanish operations in Morocco in relation to the previous decade, both in the size of the contingent involved, in the type of armament (heavy artillery, tanks, planes, and chemical weapons), and in the number of dead, wounded, and sick soldiers.Footnote 56 As a result, the Army Medical Service became rapidly overwhelmed in the Protectorate, Ceuta, and Melilla, and the peninsular military hospital network was flooded with thousands of cases of gunshot wounds, malarial fevers, tuberculosis, and other ailments.Footnote 57 Manuel Bastos returned then to active service from a long leave of absence and rushed to assume the management of limb fractures as director of the ‘fracture centre’Footnote 58 that functioned at the newly established Malaga Base Hospital between September 1921 and August 1922. That centre treated the wounded who had been evacuated in hospital ships from all over the Protectorate territory after receiving first aid care at the front and further assistance in the rear-guard hospitals of Melilla, Ceuta, Tetouan, and Larache. After the latter date, Bastos moved back to the Military Hospital of Madrid-Carabanchel, where he continued to operate fractures with his ‘surgical team’ while running a clinic for the ‘re-education of war wounded’.Footnote 59
In his Memorias, Bastos claimed to have used the closed method during the Rif War. He affirmed that in a paper published at that time he had given a detailed account of ‘my method’ of treatment with plaster dressings, which was applicable not only to simple fractures, but also to those complicated with wounds. The procedure’s novelty
lay mainly in applying it to the latter as if they were closed, that is, by immobilising the limb in plaster and not worrying about the wound, which was walled up in the dressing and deprived of any access from the outside. In those days this looked reckless. We did it with great apprehension and only in cases of linear path [gunshot] wounds. But as we saw that these healed well with the occlusive cure [cura oclusiva] regime, we proceeded to apply it systematically.Footnote 60
The article to which Bastos referred, La práctica del tratamiento de las fracturas de húmero abiertas y cerradas [Praxis of the treatment of open and closed humerus fractures], was published in October 1924 in the first issue of Tribuna Médica Española [Spanish Medical Tribune] (henceforth, Tribuna).Footnote 61 The restricted circulation of this journal led him to republish, a few months later, an offprint of the article (Figure 4). This may explain why specialists in Bastos have barely used it in their research. Another reason is that the Spanish surgeon did not coin a particular term for the technique that Orr had just christened ‘closed method’ (the equivalent Spanish term of ‘cura oclusiva’ only appeared in his 1969 Memorias). The paper presented, nevertheless, results of the application of ‘his’ method (as well as of various other treatments: osteosynthesis with Lambotte plates and Parham-Putti-Lambotte bands; suspension of the arm with irrigation and cures). Once again, the election of the humerus revealed the sustained interest of Bastos in this bone. After ten years of work and research, his approach was based on the belief that
it is very rare that a fracture of the humerus becomes life-threatening. Infection is never very serious […], probably because of the thinness of the soft tissues and the absence of strong aponeurotic septa which, in other limb segments allow infection to run along the muscle packages reaching a long distance away from the wound. From this point of view, a war fracture of the forearm is much more serious than a fracture of the arm.Footnote 62

The treatment of these fractures was thus reduced for Bastos essentially to a problem of consolidation, i.e. how to ensure a good callus formation and avoid pseudarthrosis. His surgical practice began with a restricted use of the Friedrich technique, for these fractures seldom gave reason for an intervention to clean the focus; when they exceptionally did, it was necessary to ‘restrict oneself to the ample opening of the soft parts, removing from the focus only the fragments that were absolutely loose and displaced in the soft parts or in the medullary cavity’.Footnote 63 A second step consisted of a rigorous immobilisation, ‘not just restricted to holding the arm, but keeping the shoulder and elbow absolutely motionless’, to the point that reduction became secondary as long as the arm ‘was placed in a physiological posture of relaxation of all the muscles’.Footnote 64 Bastos achieved this posture, which for all fractures of the humerus ‘is abduction of 45°, more or less, with flexion of the forearm at right angles and half rotation (i.e. the arm remaining at the level of the nipples)’, by means of an ‘abduction device’ (Figure 5) of his own design. It consisted of a circular cast stretching from the shoulder to the lower third of the forearm and leaning ‘on an iron [rod] with a fork in each extreme: the thin one is embedded into the arm cast, the large one, into a sort of cast belt that serves as support for the abduction bar [the iron rod] so that its weight does not rest on a single point of the waist’.Footnote 65 Immobilisation lasted four weeks on average, until radiographic evidence of a relatively strong callus was obtained,Footnote 66 after which the cast was replaced by a ‘tighter one, from armpit to wrist, but without abduction’ for another month, and then by a splint one last month. Despite the prolonged fixation, he never observed ‘any stiffness or limitations of movement of the elbow’ following the treatment.Footnote 67 In all cases, except in one resulting in pseudarthrosis ‘due to extensive loss of substance’, he achieved ‘a good consolidation with functional integrity’,Footnote 68 even in some in which the humerus was ‘disintegrated into innumerable fragments, which, nevertheless, later appeared all to be enclosed in a normal callus’.Footnote 69

The Tribuna article reported the results of the application of this procedure in about 50 cases of open fracture of the humerus ‘and almost as many of closed fracture’. That number was substantially higher than in Orr’s 1923 paper, but Bastos admitted that, in many of them, the plaster had been fenestrated for small wounds while for larger ones the whole area had been ‘left exposed to the air’ with the plaster covering only elbow and forearm.Footnote 70 This is consistent with the Spanish surgeon’s ‘great apprehension’ towards the new technique. Nevertheless, the fewer cases in which Bastos had truly used a closed method and for which he had gathered ‘sufficient data on their evolutive course […] from 1921’Footnote 71 paved the way for a more systematic use of the technique in later stages of the conflict, when fresh large shipments of wounded soldiers arrived at the Madrid-Carabanchel Hospital following the Chechaouene retreat of late 1924, the Al-Hoceima Landing of September 1925 and the final offensive of May 1926 that led to the surrender of the Riffian leader Muḥammad bin ‘Abd al-Karīm al-Khaṭṭābī. Although Bastos did not publish other papers on the subject, and we have hitherto failed to find clinical records or statistics in military archives, it seems plausible to think that the more extensive use of the closed method by Bastos and his team took place in those final stages of the Rif War.
The ‘abduction device’ with which Manuel Bastos treated open humerus fractures in the Moroccan war wounded externally resembled the ‘containment device’ designed in 1914 with Adolfo López-Durán for humerus fractures in children. There were, however, significant differences between them resulting from a different understanding of those fractures and a new way of applying the plaster cast. Regarding the former, López-Durán and Bastos had originally advocated for an early mobilisation of the arm by active movements of the patient, or else by massage and manipulation. Besides, the posture of the limb determined by the containment device, without being so detrimental as the one set by the much criticised ‘airplanes’ that became popular during the First World War, provoked an excessive degree of separation and elevation with respect to the trunk. Regarding the plaster cast, they had not initially applied it directly on the skin and bony reliefs, but over a gauze ‘pad’, with the consequence that it moved because ‘it rests more on certain points than on others, [and it] deflects or changes its position because the cotton layer is crushed and the infiltration of the fractured limb decreases, so this takes on an unequal weight which alters the position of the bones’.Footnote 72
This significant evolution in Bastos’ surgical practice owed much, for sure, to his intellectual skills and professional experiences. But, as just shown, it ran parallel to the work of other international surgeons whose war and post-war contributions he may have been acquainted with. The most outstanding was Orr. We believe, however, that Bastos ignored the method proposed by the American surgeon in his 1923 and 1924 papers when he treated his first Rif War patients and published his Tribuna article. The Spanish surgeon admitted ‘following Orr’s prescriptions’Footnote 73 in his classic 1936 treatise Algunos aspectos clínicos de las heridas por arma de fuego [Some clinical aspects of gunshot wounds] but did not clarify when exactly he had become a follower. Everything suggests that the American surgeon’s impact in Spain only began with his JAMA article of November 1924. Joaquín d’Harcourt, one of Bastos’ favourite disciples in Madrid, claimed in a 1939 article that ‘on ne trouve rien, dans la littérature médicale moderne, jusqu’en 1924, moment où le chirurgien nord-américain Orr préconise la cure occlusive dans les ostéomyélites chroniques’ [nothing can be found in modern medical literature until 1924, when the north-American surgeon Orr advocated the closed method as treatment for chronic osteomyelitis].Footnote 74 Josep Trueta, who represented the parallel Barcelona tradition in orthopaedic surgery and traumatology, agreed with D’Harcourt when he pointed out, in his posthumous memoirs, that ‘in 1924 there appeared an article by a North American surgeon, Winnett Orr, from Nebraska, which recommended a new technique that allowed patients to be sent home sooner than with any other treatment’.Footnote 75
The fact that Orr’s JAMA article appeared a month after Bastos’ paper makes it impossible that the latter used it. As for Orr’s 1923 article, it is highly unlikely that Bastos knew of it, given the peripheral circulation, even within the United States, of The Nebraska State Medical Journal. The last option left for Orr’s influence upon Bastos would be another JAMA article published in July 1922. However, no mention or description of the closed method was made there, not even briefly. Orr just made this short comment on the treatment of open fractures:
My principal point […] is that neither the Carrel-Dakin method nor any other kind of wound treatment should be permitted to interfere seriously with the fundamental principles in the treatment of bone and joint injuries. Those principles are, first, the immediate replacement, as nearly as possible, of injured parts in anatomic relationship, and second, the maintenance of immobilization […] of such injured parts in proper relationship until healing occurs.Footnote 76
The rise of Pedro Chutró and his impact on Bastos
It seems to us highly improbable that Bastos knew of Orr’s method during the early phase of the Rif War. However, a parallel version of the technique may have reached him before the outbreak of that conflict through the nowadays forgotten Argentinian surgeon Pedro Chutró y Cortejarana (Pila, 1880–Buenos Aires, 1938) (Figure 6). Like López-Durán, Chutró received less attention than he deserved in Bastos’ Memorias, though his importance for the Spanish surgeon can be hinted at in the following statement:
Also assiduously frequenting our clinic [at the Madrid-Carabanchel Hospital] was Professor Chutró, from Buenos Aires, who had achieved universal fame for his surgical work with the allied troops during the last great war. His lectures in various scientific and cultural centres were a great success and left a deep impression. They were all brimming with original ideas, full of good sense and profoundly innovative […] We are doing today much of what Chutró told us, though we no longer remember who taught it to us.Footnote 77

Bastos still remembered in 1969 the time ‘when the Argentinean country, so closely linked to ours, was in full splendour and at the height of its world prestige’, but most had forgotten it by then. The Nobel Prize won by Bernardo Houssay in 1947 had represented the culmination of decades of development of health innovations and biomedical research in Argentina, as well as of intense exchanges with the most advanced countries in America and Europe.Footnote 78 Spanish-Argentine circulations, in particular, boomed in the early 20th century following the renewed ‘reunion of Spain with America’ after living with their backs on each other for much of the 1800s.Footnote 79 This reunion became especially close during General Miguel Primo de Rivera’s Dictatorship (1923–30), for this took Hispano-AmericanismFootnote 80 and Hispanidad Footnote 81 as foreign policy hallmarks. Perhaps the most significant example of the extent of Spanish-Argentinian medical relations at that time was the 2nd National Congress of Medical Sciences held in Seville on 15–20 October 1924. So many Argentinians registered and/or participatedFootnote 82 that 14 out of the 15 panels had specific sub-sections for presentations by Argentinian doctors.Footnote 83
Chutró’s influence in Spain and other countries resulted from his prominent role in the First World War. With a French family background, he felt called to volunteer for France during the conflict, getting in contact with Antonin Gosset, head of the surgical service of the Pitié-Salpêtrière Hospital in Paris, with whom he had already worked in 1906.Footnote 84 At the beginning of the war, Gosset was appointed director of several military hospitals in the French capital, including the one established at the Lycée Buffon with more than 300 beds.Footnote 85 When Gosset was eventually assigned to the front, Chutró took over the direction of this hospital. He would hold it from June 1915 to April 1919Footnote 86, what gives a measure of his prestige and of the trust French authorities placed in him, as did his admission at the Société de Chirurgie de Paris Footnote 87 and his decoration with the Legion d’Honneur. During the war, Paris became a global crossroads of medical figures, ideas, and practices.Footnote 88 Numerous innovations emerged, more or less successful, as a result of these transnational circulations. In the case of the Lycée Buffon hospital, these ranged from the disinfection of wounds with the Dakin-Carrel solution, to new gas gangrene treatments, to blood transfusions, all of which spread internationally because Gosset hosted many foreign surgeons such as Chutró, the Spaniards José de Sard and Mariano Gómez Ulla, the Brazilian Mauricio Gudin or the Russian (later naturalised French) Arnault Tzank.Footnote 89 The fact that the Lycée building also housed the American Base Hospital in Paris enabled Chutró to meet US surgeons who worked there or visited the centre. According to the US government order awarding him the ‘distinguished service medal’ in July 1918, he had
devoted himself unreservedly to teaching American medical officers the principles of the lessons learned through experience by the French and British surgeons in the first years of the war, with the result that the knowledge so imparted assisted in a great measure to conserve the life and limb of thousands of American and allied wounded.Footnote 90
Among his American visitors, shortly after the signing of the armistice, was Orr himself. In his memoirs An Orthopedic Surgeon’s Story of the Great War, the US surgeon recalled that he was
[…] ordered to Paris [from Savenay] on several occasions to attend the Red Cross Hospital Conferences, and to see the work of the Base hospitals in that area. It was upon one of these visits that I had the privilege of seeing the work of Professor Chutró. He had worked out a unique organisation and an operating room and dressing technique. His service was the only absolute surgical monarchy I have ever seen. But he was doing fine surgical work and securing some excellent results.Footnote 91
The Argentinian always requested ‘the worst cases’,Footnote 92 yet his approach based on restricted surgical interventionism was consistently well appreciated by Orr and other Allied surgeons.Footnote 93A British commission noted that the dressing of wounds was renewed ‘in his hospital service only about once a week […], no bacteria chart is kept […] smears are examined only once in ten days’, and no surgical closure of infected wounds was made. In general, Chutró was not dependent upon a definite assurance that a wound was ‘clinically sound’, being satisfied if there was no suppuration, if it steadily healed, ‘and if the patient’s general condition is good and the temperature normal’.Footnote 94 More specifically in relation to fractures of the humerus, which he discussed at a session of the Société de Chirurgie in 1918, Chutró considered that the abundance of pseudarthrosis was often due to excessive intervention by the surgeon, either because of ‘an early, too large bone debridement’ which resulted in the loss of bone and periosteal substance, or because of ‘the application of containment devices causing an exaggerated exacerbation of the fragments and thus favouring fibrous interposition’.Footnote 95 Chutró rejected such procedures, advocated among others by the French surgeon Pierre Delbet, preferring immobilisation in plaster even if it ‘would not guarantee the strict reduction of fractures’.Footnote 96
In the immediate post-war, Chutró, like Orr, paid great attention to the problem of chronic osteomyelitis (he preferred the term ‘bone fistula’ for those resulting from war wounds, leaving the other name for those of ‘civilian’ origin). It was precisely because of his prestige in this subject that at the close of the war he was ‘requested to go to New York to demonstrate in the military hospital there his original methods of dealing with old, infected compound fractures with osteomyelitis’.Footnote 97 During his stay, he gave a three-month course at the New York Polyclinic,Footnote 98 a private medical school for postgraduates founded in 1882,Footnote 99 and presented a paper at the 70th Congress of the American Medical Association (AMA) held in Atlantic City in June 1919, published shortly afterwards in JAMA under the title ‘Bone fistulas after war wounds’.Footnote 100 For all these reasons, US military surgeons cited him as an authority on a disease which
has followed in the wake of all wars, but the use of high explosives and the machine gun in this war, with a consequent greater number of bone injuries, has increased proportionately its occurrence. […] Indeed, the number of its victims shakes our confidence in what we had come to believe of modern war surgery. Dr Pedro Chutró, of Buenos Aires, who has been in France since the beginning of the war, and who is recognized as one of the foremost of war surgeons, reports that there were 75,000 old suppurating bone sinuses [fistulas] in France alone at the close of 1917, the third year of the use of the Carrel-Dakin method (Chutró lately reports that there were 300,000 of these cases in France at the end of the war).Footnote 101
Orr attended the congress too, presenting a paper in the Orthopaedic Surgery section.Footnote 102 It would be of great interest to investigate whether this new encounter led to any personal or intellectual exchange between them or had any impact on the US surgeon’s subsequent research and publications on the closed method. In any case, Chutró returned to Buenos Aires, where he took over the chair of Surgery from his mentor Diógenes Decoud before taking on a ‘study trip’ to Europe in late 1920. During this new stay in France, he would be appointed foreign correspondent of the Académie de Médecine, thereby deepening his lasting professional connection with this country in which he was held in the highest esteem.Footnote 103
Chutró’s ideas on fractures and osteomyelitis reached Spain during the First World War through Spanish doctors who worked with him or visited his service. A prominent example was José de Sard, who spent several months with Chutró at the Lycée Buffon hospital. In a long lecture on the medical advances of the war at the 1st National Congress of Medical Sciences held in Madrid in 1919, Sard explained that in the treatment of femur and tibia fractures he had obtained ‘good results with the Finochietto device, introduced in France by my friend Chutró’.Footnote 104 The latter actually used it to achieve continuous traction of the limb, not temporary as Finochietto, and wrapped the metal tape (which crossed the heel above the calcaneus and behind the Achilles tendon) and the stirrup (from which the weight that made the traction hung) inside the plaster bandage, protecting both with ‘a voluminous cotton and gauze dressing, which acts as a bacterial filter’.Footnote 105 Bastos, who presented two papers at the congress, must have attended Sard’s lecture.Footnote 106 Perhaps then or after a visit to Paris in 1920,Footnote 107 he became interested in Chutró’s research. He may have learned that the Argentinian surgeon had devoted his 1904 doctoral thesis to the fractures of the upper segment of the humerus in children, a subject very similar to that of his first publication with López-Durán in 1914. And also that during the war he had approached the problem of pseudarthrosis of the humerus from a deep knowledge of the anatomy of that limb, close to his own early ‘kinematic’ approach to fractures.
Chutró’s impact on Spain’s surgery, and on Bastos in particular, was boosted by his first visit to this country in early 1921, five months before the onset of the Rif War. Invited by the Professor of Gynaecology and Obstetrics and Dean of Madrid’s Faculty of Medicine Sebastián Recasens, Chutró stayed in the Spanish capital on 13–18 February. He performed some operations at the Madrid-Carabanchel Hospital and gave four scientific lectures with great success. Two of them must have sparked Bastos’ interest, the one at the Faculty of Medicine (Figure 7) on ‘fractures of the thigh’ and the one at the Army Medical Academy on ‘sequelae following bone trauma’.Footnote 108 In the first lecture, Chutró advocated for his long-established continuous traction procedure for open fractures of the femur and tibia with only some minor modifications.Footnote 109 In the second, he dealt with pseudarthrosis following fractures of the humerus. After describing the various available procedures to prevent this problem (ligatures, metal plates, bone grafts), he nevertheless held, as he had done in 1918 at the Société de Chirurgie, to the belief that, compared to the femur and even to the forearm bones, the fractured humerus consolidated ‘easily […] with almost nothing, with a ligature and a plaster cast’,Footnote 110 provided that this cast was not applied through the device ‘used by the [North] Americans in fractures of the arm and known as “airplane”’, for this ‘causes a vicious abduction of the traumatised arm, with deviation of the scapula outwards, exceeding the costal line’.Footnote 111

We believe this lecture by Chutró, then at the zenith of his career, personality, and fame, convinced Bastos of the value of the occlusive approach in compound humerus fractures and helped him to overcome his apprehension towards it when the Rif War broke out six months later. Beyond the personal impact, Chutró’s influence on Bastos must be framed within the general adoption by the Army Medical Service during the Rif War of many organisational and technical elements that the belligerent armies had developed during the First World War. Surgical teamsFootnote 112 and blood transfusionFootnote 113 were some of the most important, but also, more specifically for Bastos, base hospitals and fracture centres.Footnote 114 The adoption of the closed approach to fractures was also due to the characteristics of warfare in Morocco. Even in the hardest period of combats between September 1925 and May 1926, many of the arm wounds continued to be linear because of the predominance of Mauser rifles over artillery and machine guns among the Riffians. Finally, the application of this procedure was favoured by the faster evacuation of the wounded, thanks to improvements in immobilisation, in the delivery of emergency surgery at the front (after the creation of first aid posts and mobile field hospitals), and in the use of ambulance cars, hospital trains and ships, and medical aircraft.
Neglected transatlantic circulations
Chutró was not just influential for Bastos’ practice of the closed method, but also for the publication of his first results. Two years on in the Rif War, he had not yet written any paper, probably due to wartime overwork, the need for prolonged follow-up of cases, the direction of the new rehabilitation service, etc. The expected attendance of Chutró at the 2nd National Congress of Medical Sciences scheduled for October 1924 in Seville broke Bastos’ impasse. As early as August 1923, Recasens, the head of the organising committee (he was born in Seville), was charged by King Alfonso XIII with crossing the Atlantic to ensure that a large representation of South American doctors attended the event, thereby reflecting the importance that the monarch attached to ‘everything related to the intellectual exchange between Spain and Latin America’.Footnote 115 The coming to power of Primo de Rivera after his coup d’etat in September only reaffirmed this plan, which was so successful that the congress, albeit national (Spanish), would be alternatively called ‘1st Ibero-American Congress of Medical Sciences’,Footnote 116 ‘Congress of Hispano-American and Luso-Brazilian Medical Sciences’,Footnote 117 and even ‘Hispano-Luso-American Congress’.Footnote 118 Bastos, whose institutional rapprochement with Recasens had resulted in his appointment as a member of the organising committee,Footnote 119 must have known very early that Chutró and other prominent Argentinian surgeons had accepted the invitation.Footnote 120 Since Chutró’s visit in 1921, he had grown used to meeting visitors from the River Plate country. Avelino Gutiérrez, for example, a Spanish emigree who worked at the Spanish Hospital in Buenos Aires and was president of the Asociación Cultural Española de Argentina [Spanish Cultural Association in Argentina],Footnote 121 visited Madrid in 1923, giving lectures on the topographical and operative anatomy of the neck that Bastos attended.Footnote 122 In January 1924, Enrique Finochietto, as renowned as Chutró, for ‘his studies on the treatment of fractures during the Great European War’, was in the Spanish capital to close a long stay in Europe that took him to Paris and other cities. He gave a lecture at the Royal Academy of Medicine on hydatid cysts of the lungFootnote 123 and operated in several surgical centres,Footnote 124 among which the Madrid-Carabanchel Hospital, where Bastos welcomed him at his service and invited him to perform ‘the most difficult operations […] but he modestly chose those of simpler execution’.Footnote 125
The expected attendance of Chutró, Avelino and Alberto Gutiérrez (father and son), and other figures of Argentinian surgery to the organised-from-Madrid-held-in-Seville congress must have moved Bastos to publish the results of his work with the wounded in Morocco. The year 1924 became one of the most prolific in his career, which was never characterised by an excess of publications. He released two papers on the treatment of fractures in the lower and upper limbs and another one about orthopaedic surgery, all three in Spanish journals.Footnote 126 The second in chronological order was his decisive Tribuna article of October 1924. There, Bastos quoted Chutró explicitly when he explained that defective immobilisation was behind
the lack of consolidation and pseudarthrosis. The humerus, like the tibia in its anterior part, has a very poor periosteum, probably due to the large surface area of free bone, i.e. without muscular insertions. There also seems to be a vascular arrangement in the arm, well studied by Chutró and [Erich] Lexer, which favours local necrosis of the fracture surfaces.Footnote 127
This article saw the light coinciding exactly with Chutró’s stay in Spain. The Argentinian surgeon disembarked in Cadiz at the end of September and, after a tour of Andalusia, travelled to Madrid to give some lectures before moving on to Seville. Chutró lectured in Madrid on 1 and 2 October on the clinic and treatment of acute osteomyelitis.Footnote 128 He also operated at Madrid-Carabanchel, where, according to the press chronicles, he ‘poured out his great mastery as a surgeon […] generously […] on the “little Spanish soldiers”, as he called them, wounded in Africa, where our army doctors, eager for these teachings, studied and admired him’.Footnote 129 Bastos, always open and supportive to the exchanges between military and civilian medicine, attended as a ‘captivated listener’Footnote 130 to these lectures, which dealt with a subject of direct interest to him. Both surgeons personally interacted with each other, first in Madrid, then in Seville (where, surprisingly, Chutró did not present any paper) and a few weeks later again in Madrid, where Chutró gave three new lectures on 20–22 October.Footnote 131 It seems plausible to think that Bastos took the chance to hand Chutró a copy of his paper.
It also seems, however, that personal contact did not have any effect as far as the closed method was concerned. In fact, Chutró devoted his gradually less frequent publications in the following years to topics ever more distanced from those which had given him international fame. Bastos, meanwhile, spent years focused on orthopedic surgery and rehabilitation before taking fractures and the closed method back as a main subject of research and publication. The two surgeons may have gotten along not so well with each other. In his Memorias, Bastos pictured the Argentinian as a ‘big-headed, dour man’, despite recognising him as a great teacher and a ‘pioneer’.Footnote 132 He also downplayed Chutró’s impact in Spain by limiting his influence to practical surgical matters such as the adequate illumination of the operating room and the use of blue-, grey- or green-coloured linen instead of white, leaving unexplained in his book ‘the many things no less useful and of no lesser evidence that Chutró placed before our eyes’.Footnote 133 This contrasts greatly with his warm memories of other Argentinian surgeons who visited MadridFootnote 134 before attending the Seville congress, such as Ángel Alsina, Alejandro Ceballos, the aforementioned Alberto Gutiérrez,Footnote 135 or Enrique Finochietto’s brother, Ricardo, who ‘spent some time at my clinic as if he were a regular collaborator’.Footnote 136 In any case, Chutró and the other Argentinian doctors turned Madrid into a crossroads in the circulation of European and American surgical practices during the 1920s, of lesser importance than Paris, London, or Berlin, but still relevant, especially because of connections with Latin America and the impact of the Rif War. Bastos had a significant role in this process thanks not just to his work with Moroccan wounded and his reception of Argentinian visitors, but also to the invitations he personally issued to figures of traumatology and rehabilitation that accepted to visit him in Madrid, such as the Austrian Hans Spitzy, the Germans Friedrich Ernst Krukenberg and Otfried Proebster, ‘Reynaldo dos Santos and [Francisco] Gentil, from Portugal, […] Araújo from Brazil, Doctors Beckers, Mayer and Van der Velde, from Belgium, [and Dr.] Rocher, from France’.Footnote 137
Chutró would return one last time to Spain in 1929. Invited again by Recasens, he stayed for over a month operating and giving lectures.Footnote 138 In a clinical session at the Madrid-Carabanchel Hospital, he dealt once more with the pseudarthrosis of the humerus, analysing its causes and explaining its treatment with bone grafts.Footnote 139 Bastos, who attended the session as on previous visits, had become by then an established figure. Apart from his rehabilitation service at the military hospital, he directed another one in Madrid’s Provincial Hospital of San Carlos and had become a lecturer at the university. Thanks to this, he built a team of civilian and military disciples in orthopaedics and traumatology. Bastos’ institutional insertion had owed much to his mentor López-Durán, whom he also replaced at the Instituto Rubio after his decease in 1930. During the period of the Second Republic (1931–36), Bastos travelled to Argentina to participate in the 2nd National Congress of Medicine held in Rosario in 1934. In Buenos Aires he operated and gave lectures at the Academy of Medical Sciences, the Spanish Hospital, the Military Hospital, and the Faculty of Medicine. Although he must have met colleagues who had visited him in Madrid in previous years, he did not mention any of them in his Memorias. Footnote 140 Neither did he mention Chutró, who died not long afterwards, in 1937.Footnote 141
No sooner had Bastos returned from that trip, a revolutionary strike broke out in Spain, with bloody clashes in the northern region of Asturias between miners and the army. Bastos practised the closed method in wounded soldiers, this time not only in fractures of the humerus (Figure 8) but also of the forearm and even of the femur ‘in well-defined cases of uncomplicated war fractures with linear trajectory’.Footnote 142 These (not quantified) cases, with others from the Rif War, were included in his already mentioned treatise Algunos aspectos clínicos de las heridas por arma de fuego published a few months before the Civil War broke out. As said before, Bastos acknowledged there that he followed ‘Orr’s prescriptions’,Footnote 143 but the absence of bibliographic references in the book makes it impossible to know to which publications of the American surgeon he was referring. Neither is it possible to know, for the same reason, in what esteem Bastos held his own pioneering article of 1924 or Chutró’s work. The book widely circulated before and during the Spanish Civil War, serving as a reference for surgeons on both sides. However, when the war was over, Bastos fell into oblivion. Trueta, D’Harcourt, and other Spanish surgeons did not reclaim his pioneering work. He was removed from the Army Medical Service by Francoist authorities and became a domestic exile, earning his life with the translation of medical treatises and private practice. He never again published on the closed method until his death in 1973.

Conclusion
Our study on Manuel Bastos has tried to ‘open’ the established historical narrative of the closed method by presenting him as a major actor and also by applying novel analytic frames. Instead of taking it as a single, univocally traceable procedure, we believe the closed method was a multidimensional development, with parallel versions emerging in different locations and transforming themselves and influencing each other as they circulated globally and were put to practice in various wars. As David Edgerton or Ilana Löwy have argued, innovations have an essentially collective character and the depiction of how some procedures come to be accepted and their authorship attributed in different historical contexts is also more important than authorship claims.Footnote 144 For the closed method, while the global crossroads of First World War Paris seems to have been the common source of all versions, the subsequent fate of each one depended on a multitude of factors, from the personal circumstances and scientific abilities of individual surgeons, to the degree of development of medicine and healthcare in their respective countries, to the greater or lesser impact of dissemination channels (journals, congresses, media) and the outcome of revolutions and wars in which they got involved. In this sense, the reconstruction of Manuel Bastos’ early trajectory and practice of the period 1909–1924 has put forward one of those lesser-known versions of the closed method with its own distinctive roots and features. Firstly, the prominence of military medicine in Spain and the fluid exchanges with civilian medicine (including non-governmental reformist institutions) that underlay the collaboration between Bastos and his mentor, Adolfo López-Durán. Secondly, the importance of the Rif War for Spain, a sort of belated First World War or anticipated Spanish Civil War in terms of the scale of military operations, the incorporation and development of medical and sanitary innovations, and the high number of dead, wounded, and sick. Finally, the neglected role of global circulations, embodied by Pedro Chutró’s trans-Atlantic mobilities between Argentina, France, the United States, and Spain and his impact on Bastos within a revival of Hispano-Americanism and in particular of Spanish-Argentinian exchanges.
