Dissociation of Sandwich Ceramic Liner: A Case Report

In total hip replacement with a sandwich ceramic liner, liner dissociation is rare. We experienced one case of sandwich ceramic liner dissociation at 3 years 7 months after total hip replacement in avascular necrosis of the femoral head. The patient was treated by revisional total hip arthroplasty and a new sandwich liner and head were fitted. We describe this one rare case and review the literature.
