title: Iatrogenic superior gluteal mononeuropathy.
abstract: Injuries to the superior gluteal nerve (SGN) have been reported as a result of trauma, pyriformis muscle entrapment, injections, and lumbar lordosis and inadequate back stabilization. We report 3 patients who developed isolated SGN injuries, 1 after a partial nephrectomy and 2 following revision of a total hip arthroplasty. SGN should be suspected in anyone developing an abnormal gait after hip or pelvic surgery or after prolonged lateral decubitus positioning.
