Electromyographic and nerve conduction studies in idiopathic ischemic necrosis of the femoral head.
Clinical features and results of nerve conduction and electromyographic investigations were studied in 13 consecutive patients with idiopathic ischemic necrosis of the femoral head. Of these patients, one was a diabetic, one had received steroids and six gave a history of high alcohol intake. Neurologic abnormalities were present in 9 of the 13 cases. Specimens were available for examination in the nine patients who underwent operation. This study suggests that disturbance in the neuromuscular system at a clinical or subclinical level could be common to idiopathic ischemic necrosis of the femoral head and its various associated disorders and might be a pathogenetic factor.
