Abstract
Iliopsoas abscess is an uncommon entity that has only rarely been associated with periprosthetic hip infection; to our knowledge, these are the first reported cases in patients with metal-on-metal (MoM) hip arthroplasty. We report 2 cases of iliopsoas abscess and concomitant periprosthetic hip infection in patients with a history of MoM hip arthroplasty. Case 1 presented with an acute infection 18 months after revision total hip arthroplasty (THA) for instability and adverse local tissue reaction after MoM THA. Case 2 presented with an acute infection in a previously well-functioning MoM THA. Both cases were treated with combined hip and retroperitoneal approaches and required more aggressive and longer treatment than is typical for periprosthetic infection, but ultimately resulted in successful revision THAs. We outline the treatment of these 2 patients and review the previously reported literature.
