Twenty-five patients with un-united fractures were treated by direct current stimulation through percutaneous electrodes. Average duration of non-union was 44 weeks. Eighteen out of 20 cases o non-union had undergone one or more prior surgical procedures, besides prolonged immobilization in plaster casts. Twenty-one out of 25 cases united and returned to their previous occupation. The semi-invasive technique is simple and relatively free complications. The electrical apparatus is light and portable and can be used with ease by the patient at home.
