summary Trochanteric bursitis is a very common source of lateral hip pain caused by repetitive trauma secondary to iliotibial band tracking over the trochanteric bursa. Diagnosis is made clinically with point tenderness over the greater trochanter. Treatment is conservative with NSAIDs, stretching, physical therapy and corticosteroid injections. Epidemiology Demographics often occurs in female runners Risk factors Is associated with training on banked surfaces Etiology Pathophysiology pathoanatomy repetitive trauma caused by iliotibial band tracking over trochanteric bursa can irritate the bursa causing inflammation Anatomy Trochanteric bursa is superficial to the hip abductor muscles and deep to the iliotibial band Presentation Symptoms lateral sided hip pain, although hip joint is not involved Physical exam pain with palpation over greater trochanter Imaging Radiographs will be unremarkable MRI will show increased signal in bursa due to inflammation on T2 sequence Treatment Nonoperative NSAIDS, stretching, PT including modalities, corticosteroid injections indications first line treatment is always conservative Operative open vs arthroscopic trochanteric bursectomy indications is done only after conservative measures fail
