Abstract

A recent development in fracture treatment is that of electrical stimulation to enhance healing. Since the fractured limb receiving treatment may have been inmmbilized or fixed with 316L stainless steel (SS) internal fixation devices, there is an interest in docu.menting how the electromagnetic field affects corrosion of this alloy. The stimulator under investigation produces an electrcnagnetic field having a 3.5 ± IMV pulse height delivered at 75 Hz within the treatment coils. Corrosion, as quantified by analyzing test solutions for Ni and Cr levels, was measured for specimens in and out of the stimulator field.

Three-week in vitro corrosion tests were conducted at 37°C in 0.9% NaCl adjusted to pH levels of 7.4 and 4.0. Specimen were 316L SS rods with surfaces finished to 600 grit. 0-rings were added to form crevices in order to accelerate corrosion. Stimulation was continuous for test specimens. An equal number (ten for each pH) of control specimens received no stimulation. A statistical comparison of the data reveals that at a 95% confidence level the stimulator field did not affect corrosion of the 316L SS.
