Once Annealed Highly Cross-Linked Polyethylene Exhibits Low Wear at 9 to 15 Years.
A once annealed highly cross-linked polyethylene (HXLPE) was introduced in 1998. Concerns regarding its long-term performance and oxidative resistance exist because of the presence of retained free radicals. The authors studied 48 patients with 50 hip implants having an average age of 62 years. They were followed for 9 to 15 years. The purpose of this study was to determine linear wear rate and...
متن کاملWear of Highly Cross-linked Polyethylene against Cobalt Chrome and Ceramic Femoral Heads
+*Jennings, L M; *Galvin, A L; *Fisher J +Institute of Medical & Biological Engineering, Leeds, UK [email protected] Introduction There is increasing interest in the coupling of highly cross-linked polyethylene with large diameter heads in the hip, due to the reported lower wear characteristics of highly cross-linked polyethylene compared to conventional polyethylene [1, 2, 3]. Further, ...

متن کاملHip Resurfacing Using Highly Cross-linked Polyethylene: Prospective Study Results at 8.5 Years.
BACKGROUND Hip resurfacing is an option to consider when treating younger, more active patients. Advantages over total hip arthroplasty include a more normal gait and a lower incidence of thigh pain. METHODS In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly ...
