Allograft Reconstruction of Acetabular Bone Defects Combined with Reinforcement Ring in Revision Total Hip Arthroplasty

Reconstruction of bone defects in revision total hip replacement (THR) after loosening of the prosthesis is often difficult, because of the size of the bone defect [1,2, 3]. In revision THR, a large amount of autogenous bone is difficult to obtain. The femoral head has already been removed and many of these patients are elderly so that the cancellous bone of the ipsilateral iliac crest is remarkably porotic. For these reasons it would be attractive, where it is possible and clinically successful, to use allografts from the bone bank. Particularly in middle-aged patients, where the possibility of the next revision surgery has to be strongly considered, high placement of the acetabular component should be avoided. Accordingly, by generous use of frozen allograft, we repaired the bone defects and mounted the acetabular component in an anatomical position for such patients [3, 5]. This paper presents a retrospective study on repair of bone defects with allografts and the fate of the grafts.
