The peritrochanteric space of the hip.

The field of hip arthroscopy continues to grow as surgeons become more familiar with disorders of the intra-articular and extra-articular compartments of the hip. Recent studies have described the endoscopic treatment of injuries to the lateral peritrochanteric compartment of the hip, including recalcitrant trochanteric bursitis, external coxa saltans, and tears of the gluteus medius and minimus tendons.
