IATROGENIC SUPERIOR GLUTEAL MONONEUROPATHY

Injuries to the superior gluteal nerve (SGN) have been reported as a r esult of trauma, pyriformis muscle entrapment, injections, and lumbar lordosis and inadequate back stabilization. We report 3 patients who d eveloped isolated SGN injuries, 1 after a partial nephrectomy and 2 fo llowing revision of a total hip arthroplasty. SGN should be suspected in anyone developing an abnormal gait after hip or pelvic surgery or a fter prolonged lateral decubitus positioning. (C) 1998 John Wiley & So ns, Inc.
