Periprosthetic fractures of the acetabulum (hip socket)

A 46-year-old female sustained a periprosthetic acetabular fracture 1 month following a revision Total Hip Arthroplasty (THA) procedure.

She was referred to David L. Helfet, MD at the Orthopaedic Trauma Service of the Hospital for Special Surgery for definitive management of her periprosthetic acetabular fracture.

Open Reduction and Internal Fixation (ORIF) was performed with placement of 2 pelvic reconstruction plates and screws and bone graft.

She returned for regular follow-up and healed uneventfully and at 6 months following surgery she presented with excellent radiographic and clinical results including a healed periprosthetic acetabular fracture, resolution of hip pain, and return to her activities of daily living.
