KEY FACTS

      • Top Differential Diagnoses

        • Clinical Issues

          TERMINOLOGY

          • Definitions

            • Impingement of iliopsoas muscle and tendon against femoral head
              • Small number of these patients present with snapping hip syndrome ("coxa saltans")
                • Tendon abruptly moves over femoral head
                • Patient experiences "snap" with motion, may be painful
