Total arthroplasty of the hip by fritted alumina prosthesis. Experimental study and 1st clinical applications

Abstract

A new material is proposed in total hip arthroplasty as a bearing component. The tolerance of dense ceramics was studied, as well as the anchorage of this material into bone. Physical, chemical and mechanical properties of the prosthesis were tested. Two hundred patients have already been operated on, but the follow-up is too short for any conclusion.

Ceramics and ceramic coatings in orthopaedics

“…Interest in polycrystalline bioceramics started in 1970 when Dr. Pierre Boutin implanted the first hip prostheses with Al 2 O 3 ceramic bearings [15,16]. His success led to a string of ceramic biomaterial innovations, with patents appearing shortly thereafter claiming various ceramics, including Al 2 O 3 , as viable orthopedic materials [17][18][19][20].…”

Evidence Linking Elevated Oxidative Stress and Aseptic Loosening of Hip Arthroplasty

“…This led researchers and clinicians to propose other causes for osteolysis and subsequent loosening such as polyethylene and metal debris. The first ceramic-on-ceramic (CoC) total hip arthroplasty was developed by Boutin in 1970(Boutin, 1971, Boutin & Blanquaert, 1981. The main advantages of ceramics are its superior wear characteristics and biocompatibility, along with better corrosion resistance compared to metallic alloys.…”

Do the Reasons for Ceramic-on-ceramic Revisions Differ From Other Bearings in Total Hip Arthroplasty?

“…Ceramic-on-ceramic (CoC) bearings were introduced in THA more than 40 years ago [3]. This bearing was expected to minimize the rate of long-term revisions because of its excellent tribologic properties and generation of inert wear debris [12,22,29].…”
