Ceramic On Highly Cross Linked Polyethylene

Dependence on walking aids and limp had decreased substantially at the time of final follow up.

Ceramic on highly cross linked polyethylene.

Below you will find an overview of the available sizes and many combination possibilities. 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. In the ceramic on highly cross linked polyethylene group the mean preoperative harris hip score was 37 points range 11 45 points which improved to 95 points range 85 100 points at the time of final follow up. Stambough md said in his presentation.

Cross linked polyethylene articulating against 22 225 mm alumina ceramic was observed after the first two years 5. 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. 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.

Biolox forte and biolox delta ball heads and cup inserts can be combined with ceramic components from the biolox family of products as well as with inserts made from conventional and highly cross linked polyethylene. Removable longevity liners are available in neutral elevated oblique and 7 mm offset. 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. There are two components of the hip joint.

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.
