Abstract

The obturator nerve is originated in lumbar 2, 3, 4 roots and inserted at the inner muscle of thigh, by way of sacral ala and obturator foramen. In the case of pelvic surgery or obstetric trauma, the obturator neuropathy is occasionally occurred. However, the obturator neuropathy is rarely seen in the orthopedic accident. In literature, one case of obturator neuropathy is reported after 2,012 cases of total hip replacement surgery. The useful diagnostic tools of obturator neuropathy are needle EMG on the obturater nerve innervated muscle, not conduction test on the nerve. We report of a case of obturator neuropathy after closed reduction of posterior hip dislocation complicated by traffic accident with a brief reviewed of literatures.
