title: Position of the sciatic nerve and effect of gluteus maximus release during hip arthroplasty.
abstract: Eight Thiel embalmed hips were dissected. The distance between the sciatic nerve and the femoral neck was measured before and after hip dislocation, and before and after release of the gluteus maximus tendon. There was a significant reduction in the mean distance between the neck of femur and the sciatic nerve in both the gluteus maximus tendon release and the unreleased groups at 60° and 90° of hip flexion, p < 0.05. The mean distance between the neck of femur and sciatic nerve was greater in the release group for all positions.
