Wear of highly crosslinked polyethylene acetabular components
BACKGROUND AND PURPOSE Wear rates of highly crosslinked polyethylene (XLPE) acetabular components have varied considerably between different published studies. This variation is in part due to the different techniques used to measure wear and to the errors inherent in measuring the relatively low amounts of wear in XLPE bearings. We undertook a scoping review of studies that have examined the i...
متن کاملVivacit-E® Vitamin E Highly Crosslinked Polyethylene Long-term Performance For High Demand Patients
Total joint replacement is being performed on younger patients who expect to remain active throughout their lifetime, and as such this demographic shift has created a need for long-term implant bearing performance. First introduced in the 1990s, highly crosslinked polyethylene (HXPE) has demonstrated promising wear properties through the first decade of in vivo use. Recent studies, however, hav...
متن کاملIn vivo wear particles of remelted highly crosslinked polyethylene after total hip arthroplasty: report of four cases.
This is the first report of in vivo wear particles from four total hip arthroplasties using remelted highly crosslinked polyethylene. The number of particles was (1.51 ± 0.45) × 10(7) g(-1) (mean ± standard error); particle size (equivalent circle diameter), 0.72 ± 0.15 µm; and roundness, 1.45 ± 0.05. Remelted highly crosslinked polyethylene generates fewer, rounder, equivalently sized particle...
متن کاملIn Vivo Wear Particles of Annealed Highly Cross-Linked Polyethylene in Total Hip Arthropalsty
INTRODUCTION: Polyethylene wear particles induce cytokine release by macrophage, which leads to osteolysis and aseptic loosening in total joint arthroplasties. Generation of polyethylene wear particles is one of the most important factors that affecting mid-term and long-term results of total hip arthroplasty (THA). Therefore, to reduce wear generation and to achieve better long-term results of...
