A Case of Iliopsoas Bursitis With Compressive Femoral Nerve Palsy Treated With Iliopsoas Tendon Release

Iliopsoas bursitis is a well-established cause of groin pain after total hip arthroplasty (THA), and it can become dramatically more complex when associated with neurovascular compression. Iliopsoas bursitis may be caused by a variety of pathologies in the setting of a THA but most frequently due to a prominent acetabular component or implant wear. Here we report a rare case of a female patient presenting with iliopsoas tendonitis, an accompanying femoral nerve palsy, and debilitating pain beginning 12 years after a previously successful primary THA without apparent implant wear. Ultimately, our patient was treated successfully with iliopsoas tendon release for anterior prominence of the acetabular component.
