Radiologic Evaluation of the Treatment of Nonunion of Fractures by Electrical Stimulation

Abstract

A procedure is described in which nonunion of fractures is treated by implantation of electrodes with direct electric current at the site of fracture. Of 107 patients treated with electrode stimulation, 71 (66%) healed. If one eliminates 9 cases of congenital pseudoarthrosis and 11 patients treated with only 10 microamperes of current, 70 of 87 patients (8095%) healed. Severe osteoporosis and sclerosis were common radiologic findings, but had no value in predicting which patients would respond to therapy.
