Ceramic On Highly Cross Linked Polyethylene

Stambough md said in his presentation.

Ceramic on highly cross linked polyethylene.

The aim of this study was to determine the wear of large size 36 mm highly cross linked polyethylene inserts against ceramic and cobalt chrome femoral heads using a physiological hip simulator and test conditions. The use of ceramic heads in conjunction with highly cross linked polyethylene is supported in the literature 4 5 and relies upon the principles of increased scratch resistance increased. Removable longevity liners are available in neutral elevated oblique and 7 mm offset. To help ensure optimal wear resistance zimmer biomet employs a proprietary process.

A the acetabulum or the cup that replaces the hip socket and is generally made out of ultra high molecular weight polyethylene or highly cross linked polyethylene metals and ceramics fig. The crossfire polyethylene insert stryker orthopaedics was used for all cases in which a highly cross linked polyethylene liner was implanted with the biolox forte ceramtec plochingen germany used as a ceramic liner and head. Dependence on walking aids and limp had decreased substantially at the time of final follow up. A ceramic on highly cross linked polyethylene coxpe articulation may decrease long term wear and potentially have a longer survivorship with less ceramic fracture and squeaking than coc bearing surface and is increased use in the younger population less than 65 years old over the last 5 years as demonstrated in the national joint registry.

The latest generation of ceramic on polyethylene biolox delta on highly cross linked polyethylene has shown an excellent linear wear rate 0 006 mm yr which is much lower than previously found wear rates for cobalt chrome on highly cross linked polyethylene 0 011 mm yr. Ceramic on highly cross linked polyethylene in young active patients provides excellent mid term wear and component survivorship jeffrey b. Below you will find an overview of the available sizes and many combination possibilities. 8 2 or a combination thereof and b the metal or ceramic head attached to a metal stem that is inserted into the femur to provide stability to the prosthesis.

Cross linked polyethylene articulating against 22 225 mm alumina ceramic was observed after the first two years 5. Longevity highly crosslinked polyethylene longevity crosslinked polyethylene was developed to address the issue of wear in total hip arthroplasty.
