title: Electromyographic and nerve conduction studies in idiopathic ischemic necrosis of the femoral head.
abstract: 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.
