Ceramic On Ceramic Bearings In Total Hip Arthroplasty

The clinical use of ceramic as a bearing surface dates back to the early 1970s.

Ceramic on ceramic bearings in total hip arthroplasty.

This study aims to report the risk of revision for fracture of modern coc bearings and identify factors that might influence this risk using data from the national joint registry njr for england wales northern ireland and the isle of man. This study aims to evaluate the results of coc bearing tha in patients younger than 50 years. Ceramics are extremely hard scratch resistant and biocompatible as well as demonstrating a low coefficient of friction. Alumina ceramic on ceramic bearings in cementless primary total hip arthroplasty has been shown to have good survival rate at 10 years with good functions low wear rate and no adverse radiographic changes.

It is also resistant to third body wear. This makes ceramic an ideal bearing material for total hip arthroplasty. In 1995 an improved alumina ceramic was developed that had increased purity and strength over the first generation materials. The type of ceramic used in total hip replacement today is aluminum oxide also known as alumina.

In conclusion ceramic on ceramic total hip arthroplasty produced excellent clinical results and implant survival rates with no detectable osteolysis at a minimum of six year follow up study. Cai p hu y xie j. The results of ceramic on ceramic coc total hip arthroplasty tha in younger patients were not univocal. Results of a multicenter prospective randomized study and update of modern ceramic total hip trials in the united states.

Coc has very low wear rates both for linear and volumetric wear. The ceramic on ceramic total hip arthroplasty was a reasonable option of variable indications for primary total hip arthroplasties. Large diameter delta ceramic on ceramic versus common sized ceramic.
