Abstract
Surgical Principles With the increasing frequency of total joint replacement, the orthopaedic surgeon is often confronted with cases of aseptic, time related loosening of total hip arthroplasties. This is compounded by the severe bone loss associated with loosening and the reaction to particular debris [3, 9, 11]. Conventional methods of revision can be difficult and even inadequate for some of these situations [2, 8, 15, 17]. The use of structural allografts for significant proximal femoral deficiencies can restore skeletal architecture and mechanical integrity to these patients. The aim of this technique is to allow the reconstruction of large structural defects with a physiologically compatible material rather than the traditional techniques of custom prosthetic replacement with or without extensive cement augmentation.
