Early Fracture of the Trunion in Total Hip Arthroplasty: A Case Report

A 59-year-old man who had previously undergone total hip arthroplasty (THA) with the use of a dual modular (head and neck) total hip implant presented with a mechanical failure at the trunion 9 yr after index surgery with a low-energy mechanism. The fractured stem was then removed and a revision stem implanted to restore the patient's ability to ambulate. We demonstrate and contribute to the small but growing evidence of failure of modular THA systems at the trunion.
