The Snapping Iliopsoas Tendon: New Mechanisms Using Dynamic Sonography

摘要: OBJECTIVE. The purpose of our study was to describe new mechanisms responsible for the snapping iliopsoas tendon using dynamic sonography.MATERIALS AND METHODS. We reviewed video recordings obtained during sonography studies used establish diagnosis 18 tendons in 14 patients (nine females and five males; age range, 13–50 years) who presented clinically with either unilateral (n = 10) or bilateral 4) hips. During imaging, transducer positioned a transverse oblique plane just above hip joint parallel pubic bone. For all patients, movement that generated consisted bringing from flexion–abduction–external rotation back neutral position.RESULTS. In hips, provoked by sudden flipping around iliac muscle, allowing abrupt contact against bone producing an audible snap. Other causes tend...
