Introduction

Since the introduction of the low-friction hip arthroplasty by Charnley, there have been numerous attempts to improve the wear characteristics of metal on polyethylene. Boutin, in 1970, introduced the first ceramic total hip replacement. Ceramic components have been shown to have better wear characteristics than stainless-steel and metal-alloy components because of their hard, scratch-resistant surface; hydrophilic surface properties (wettability); corrosion resistance; and excellent biocompatibility8,13. As wear debris is one of the major factors responsible for failure of a total hip arthroplasty, the use of a ceramic femoral head for a revision operation is very appealing4,5,18. It is not uncommon to find wear of the acetabular component with osteolysis and a well fixed femoral stem. The use of a ceramic femoral head for a revision may be justified in that situation, especially if the patient is young. However, ceramic has a high elastic modulus, which means that it is . . .
