Hemiresurfacing arthroplasty of the hip for failed free-vascularized fibular graft.

摘要

Management of Ficat stage III and IV osteonecrosis of the hip remains challenging, with the average patient aged in the mid 30s. Joint- and bone-preserving procedures such as free vascularized fibular graft, redirectional osteotomies, and hemiresurfacing hip arthroplasty are often considered. If these treatments fail, that is, after progression of joint destruction or persistent pain and decreasing function, total hip arthroplasty is often the procedure of choice. We describe the case of a patient with failed bilateral free vascularized fibular graft treated with bilateral hemiresurfacing arthroplasty.
