Abductor Tendinopathies and Repair

Abstract

A thorough understanding of the peritrochanteric compartment disorders and greater trochanteric pain syndrome (GTPS) is important for the orthopedic surgeon given its high prevalence, reported to affect between 10% and 25% of the general population. This clinical entity includes trochanteric bursitis, external snapping hip, and tears of the gluteus medius and minimus. Patients typically present with pain and reproducible tenderness in the region of the greater trochanter, buttock, or lateral thigh. Enhanced knowledge of the functional anatomy about the greater trochanter has been obtained via advances in diagnostic imaging tools and in hip arthroscopy. An understanding of the common presentation, physical examination, and radiographic findings associated with GTPS will enable the treating physician to sort through the broad differential diagnosis that accompanies a patient presenting with lateral sided hip pain. Although conservative management should still be the mainstay of treatment, open or endoscopic treatment of these disorders provides an additional treatment option for refractory cases. When properly indicated, the endoscopic surgical intervention can lead to symptom relief and a return to normal function. A thorough knowledge of each disease entity, arthroscopic hip anatomy, and arthroscopic technique is of paramount importance for successful outcomes and satisfaction of patients presenting with lateral hip pain.
