The superior gluteal nerve exits the greater sciatic foramen above the piriformis with the superior gluteal vessels, running between the gluteus medius and minimus to supply both muscles and the tensor fasciae latae. It is the sole motor supply to the hip abductors and TFL. Its safe zone during posterolateral hip approaches is more than 5 cm proximal to the greater trochanter tip.
The superior gluteal nerve safe zone limits the proximal extent of posterolateral hip incisions and fasciotomy. Injury produces an abductor lurch (Trendelenburg gait) from gluteus medius and minimus paralysis. It is stretched by prolonged lateral positioning during surgery and by excessive retraction in the deep gluteal space. In total hip arthroplasty, superior gluteal nerve monitoring with intraoperative EMG is used in some centres. Recovery after traction injury typically occurs over 3-12 months.
Hip abductor paralysis from superior gluteal nerve injury producing Trendelenburg gait, inability to maintain pelvic level during single-leg stance, and progressive hip abductor atrophy.
