Isolated superior gluteal nerve injury: Two case reports

Isolated superior gluteal nerve injury has been infrequently described in the literature, mainly from injections or hip surgery. Its course through the greater sciatic foramen renders it at risk in pelvic or hip trauma. We report 2 cases of electromyographically documented isolated superior gluteal nerve injury following pelvic trauma. These cases illustrate that weakness in hip abduction following pelvic trauma may indicate the presence of a superior gluteal nerve injury, warranting further clinical and electrodiagnostic evaluation.
