Peritrochanteric Space Disorders: Anatomy and Management

Abstract

The peritrochanteric space is an important area to be considered in the differential diagnosis of hip pain. Greater trochanteric pain syndrome (GTPS) is a term used to describe the most common causes of lateral hip pain: trochanteric bursitis, external coxa saltans (snapping hip), and gluteus medius pathology. Understanding GTPS requires an in-depth knowledge of the peritrochanteric space anatomy. Standard radiographs, ultrasound, and magnetic resonance imaging are useful modalities to diagnose and treat GTPS. The treatment of GTPS is typically nonoperative with anti-inflammatories, corticosteroid injections, and physical therapy. Refractory cases are amenable to surgical treatment using peritrochanteric endoscopy or open techniques.
