Ceramic on highly cross linked polyethylene hip.

Pritchett explains why the synovo preserve is an excellent hip resurfacing device and how it is different than metal on metal devices. Turning now to the comparison of ceramic on ceramic versus highly cross linked polyethylene that has been melted the advantages of metal on polyethylene over ceramic on ceramic articulations for total hip replacement surgeries are multiple and important. Biolox delta ceramic offers low wear rate in a material with improved mechanical properties compared to traditional ceramics. 2 3 this remarkable process creates a three dimensional structure that is more resistant to abrasion.

4 5 longevity highly crosslinked polyethylene was developed to. A randomised prospective evaluation of ceramic on ceramic and ceramic on highly cross linked polyethylene bearings in the same patients with primary cementless total hip arthroplasty. Our aim was to calculate the 5 to 10 year wear rate and the incidence rate of osteolysis for 3 types of bearings. Objective currently there is a lack of evidence on the medium term follow up of cementless total hip arthroplasty tha using metal on highly cross linked polyethylene mop ceramic on ceramic coc and metal on metal mom bearings.

Crosslinking has been shown to reduce the wear rate of polyethylene by up to 89 in laboratory studies. 1 clinical experience with highly crosslinked polyethylenes has also demonstrated a substantial reduction in the rate of wear. The latest generations of ceramic on highly cross linked polyethylene has the potential to become the new gold standard in tha. Advances in these materials could increase survivorship significantly to 20 25 or even 30 years.

Currently long term survivorship of ceramic on polyethylene is between 90 and 97.
