Alloprosthetic composite is a suitable reconstruction after periacetabular tumor resection

Abstract

Background: Resection of a tumor of the pelvis is most disabling when the acetabulum is excised and a durable reconstruction of the defect is hard to achieve. All available methods are associated with frequent complications. Few large series have been published, and fewer have focused entirely on complete resections of the acetabulum. The use of an allograft-prosthetic composite allows customization on the operating table. However, while such composites restore anatomy and function of the pelvis the use of pelvic allografts is controversial and the durability is unknown. Questions/purposes: We therefore examined (1) the frequency of allograft and prosthetic failure, (2) positive and negative..
