title: Iliopsoas tendon rupture: a new differential for atraumatic groin pain post-total hip arthroplasty.
abstract: Groin pain post-total hip arthroplasty (THA) is of concern for the patient and the surgeon, especially when there is no history of any traumatic event. Obvious concern centres on complications from the prosthesis. The use of multiple imaging modalities allow for accurate diagnosis of groin pain. Atraumatic iliopsoas rupture is rare and has only been reported once before in the setting of THA. We present the case of 53-year old female with atraumatic rupture of the iliopsoas tendon that presented with severe groin pain and limited flexion. We discuss the clinical presentation, radiological features and follow-up of the patient. We also discuss the relevant published literature on the topic. This is a rare phenomenon but should be consider in patients with groin pain post-THA, especially after prosthesis complications have been ruled out.
