Acetabular bone conservation was assessed using computed tomography by measuring the medial acetabular wall. Highly cross-linked polyethylene as a bearing surface for hip resurfacing produced satisfactory functional results, bone conservation, maintenance of biomechanics, and implant survivorship. Background: In the 1970s and 1980s, hip resurfacing was largely unsuccessful, due to impingement, wear, and component loosening. Conclusions: Resurfacing with a highly cross-linked polyethylene acetabular component and a titanium nitride-coated titanium cementless femoral component is a reliable and bone-conserving procedure at mid-term. This is an anteroposterior radiograph of a 44-year-old woman FOIA J Arthroplasty. 8600 Rockville Pike Two types of cementless 2-piece polyethylene acetabular components were used: the Trident PSL with the 3.8-mm X3 polyethylene liner (Stryker) or the Endotec BP (Endotec). The 3D optical scanner had an average accuracy of 2.1 µm and an average precision of 1.4 µm, which corresponded to errors less than 10% when measuring wear depths of 20 µm or greater.

Synovo Preserve cementless, ceramic coated titanium, cross-linked polyethylene hip resurfacing device. Highly cross-linked polyethylene (HXLPE) has been and continues to be commonly used for liners in total hip arthroplasty (THA) due to its known ability to reduce wear during articulation. Wear rate of highly cross-linked polyethylene in total hip arthroplasty. Kaplan-Meier survivorship was 97%. Hip resurfacing is an option to consider when treating younger, more active patients. Retrieved polyethylene liners were analyzed for wear. highly cross-linked polyethyl-enes were introduced for clini-cal use.

For full disclosure statements refer to http://dx.doi.org/10.1016/j.arth.2016.03.013. One participant underwent successful revision surgery for acetabular loosening. However, a potential problem with reducing liner thickness with highly cross-linked polyethylene is that thin liners are potentially more susceptible Although results from these studies are encouraging, the acetab-ular component used in these studies was still over twice as thick as a standard MoM hip resurfacing device. The low incidence of osteolysis and the low rate of wear found on retrievals suggest that many years of use in highly active patients is possible. HSS J. Chapter 71 Highly Cross-Linked Polyethylene Bearings J. Benjamin Jackson III., John L. Masonis and Thomas Fehring Key Points • Highly cross-linked polyethylene has demonstrated wear rate reduction of between 40% and 95% over conventional polyethylene.

Conclusions: Hip resurfacing today has proven to be a successful procedure with results as good as or better survivorship than total hip replacement and better function. The manufacturing process for these materials cross-links the molecules and im­proves wear characteristics but slightly reduces the strength of the polyethylene.
