Highly Cross-linked Polyethylene — A New Option in Tribology of THA
Highly cross-linked polyethylene Durasul was introduced at our hospital in March 1999. In vitro results regarding wear behaviour from different laboratories are very encouraging. Durasul polyethylene inlays showed after 27 million cycles no measurable wear in an AMTI hip simulator study. The ultra-low wear was masked by the minute fluid uptake from the serum. To date, only few in vivo results exist and show a tendency that Durasul resists to wear better than conventional polyethylene . Thus, there is still a demand for investigations using early wear detection methods in order to expose a minimum number of patients to the risk of material failure.
