MR Imaging Diagnosis of Greater Trochanteric Syndrome

Greater trochanteric syndrome (GTS) is a common condition clinically manifested by pain and tenderness over the greater trochanter. MR imaging plays a pivotal role in investigating the underlying cause of GTS. MR imaging can detect abnormalities not only in symptomatic but also in asymptomatic hips, thereby revealing structural damage in the gluteal tendons and muscles during both clinical and preclinical phases. This review article emphasizes the importance of detailed knowledge of anatomy of the greater trochanter and adjacent soft tissues, along with the imaging appearance of pathology of the abductor tendons and muscles as well as the peritrochanteric bursae.
