Ceramic-on-Ceramic THR Necessitating 44- or 46-mm Metal Shells Study
…A small cup limits options regarding liner thickness and femoral implant size. The purpose of this study was to evaluate the safety of a 4-mm–thick ceramic liner and the outcomes of cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing…
…Between May 2003 and June 2008, 80 patients (88 hips) who had hip osteoarthritis and a hypoplastic acetabulum underwent cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing…
…The thin (4 mm) ceramic liner did not increase the risk of ceramic fracture and did not affect the mid- to long-term results
