RESUMEN
The etiology of hip discomfort and tendinitis often is confusing and the differential diagnosis is large. Some entities are overlooked because diagnosis requires appropriate clinical awareness and a specific radiographic examination. Coxa saltans, or snapping hip, is one of those commonly overlooked diagnoses. There are three types of snapping hip--the internal type, the external type, and the intra-articular type--and each presentation is unique. Most are symptomatic, but some may be quite painful and disabling. Evaluating the hip structures with bursography under dynamic conditions often is helpful to evaluate the anatomy and determine the etiology of the snapping hip. Treatment may range from conservative physical therapy, to corticosteroid injections, to arthroscopic treatment.
