Fig. 2A–B.

The radiographs of a 24-year-old patient with groin pain consistent with iliopsoas impingement after total hip resurfacing performed for posttraumatic arthritis are shown. (A) The cup is not prominent anteriorly; however, the large femoral head is prominent and somewhat medialized on the femoral neck. (B) Also, a screw tip projects into the pelvis that may irritate the iliacus muscle. The patient experienced moderate groin pain that was relieved with an ultrasound-guided iliopsoas tendon sheath injection.
