Greater Trochanter

trochanter major femoris

The greater trochanter is the large bony prominence at the proximal lateral femur, serving as the insertion site for the gluteus medius, gluteus minimus, piriformis, obturator internus, gemelli, and obturator externus muscles. It is the primary muscle attachment point for hip abduction and external rotation, and its fracture from high-energy trauma or avulsion in young athletes disrupts these functions. Greater trochanteric pain syndrome involves tendinopathy and bursitis at this prominently subcutaneous landmark.

Clinical Notes

Greater trochanter apophyseal avulsion fractures in adolescent athletes (particularly gymnasts and sprinters) occur from sudden hip abductor contraction, producing lateral hip pain and inability to abduct. Displaced avulsions (greater than 1 to 2 cm) may require surgical fixation. In adults, greater trochanteric fractures in hip arthroplasty from periprosthetic fracture require fixation with claw plate devices. The greater trochanter is the primary landmark for hip arthroplasty posterior approach incision placement.
