Trochanteric Bursa

bursa trochanterica

The trochanteric (principal) bursa is the largest bursa at the greater trochanter, lying between the posterior gluteus medius tendon and the posterior facet of the greater trochanter. It is distinguished from the other trochanteric bursae (gluteus medius and minimus) by its posterior location and larger size. It is the bursa most commonly injected for greater trochanteric pain syndrome.

Clinical Notes

Greater trochanteric pain syndrome (GTPS, formerly called trochanteric bursitis) produces lateral hip pain reproduced by palpation of the posterior greater trochanter and by resisted hip abduction. The pain pattern extends to the lateral thigh and is worse lying on the affected side. Modern understanding recognises that gluteus medius and minimus tendinopathy is the primary driver in most GTPS cases, with bursitis secondary to tendon degeneration. Ultrasound-guided corticosteroid injection into the principal bursa provides diagnostic confirmation and therapeutic relief. PRP injection and surgical gluteal tendon repair address refractory cases.

Greater Trochanteric Pain Syndrome

Lateral hip pain from gluteus medius tendinopathy with secondary trochanteric bursitis, worsening with side-lying and single-leg activities — managed with load modification and gluteal strengthening.
