title: Iliopectineal bursitis complicating hemiarthroplasty: a case report.
abstract: Enlarged iliopectineal bursitis in the hip region, which usually occurs with degenerative, infectious, or traumatic disorders, is relatively rare. Iliopectineal bursitis complicating bipolar hemiarthroplasty is even more rare. Reported here is an unusual case of a patient with an inguinal mass presenting 8 years after bipolar hemiarthroplasty. Enlarged bursitis complicating the hip prosthesis is rare and has been described only anecdotally in the literature. The enlarged iliopectineal bursa arises from the hip, and the most apparent cause of its formation is polyethylene debris. Treatment should be directed at the source of the debris intraarticularly. Wearing of the polyethylene insert was difficult to discern radiographically for this patient; it was seen on the scout film of the computed tomography of the pelvis while evaluating the enlarged bursitis. The scout film of the computed tomography and the two-dimensional reconstruction of computed tomograms of the hip may be helpful in evaluating wearing of the polyethylene insert.
