Stabilisation of UHMWPE with Vitamin E

This paper describes recent findings by the University of Torino related to Vitamin E stabilization of UHMWPE. Vitamin E is found to be an effective and practical stabilizer for preventing oxidation of UHMWPE during consolidation and following irradiation. This paper was presented on March 18, 2005, at the UHMWPE meeting at the University of Torino.

Morphological Analysis of Retrieved Cross-linked UHMWPE and Improved Microstructures for Enhanced Fatigue and Wear Performance

This paper discusses the effect of cross-linking on the fatigue properties of UHMWPE and examines the role of cross-linking on clinical performance in total joint replacements. Additionally, this work seeks to examine the role of morphology on the mechanical behavior of UHMWPE and the ability to optimize fatigue and wear behavior with optimized microstructure. This paper was presented on March 18, 2005, at the UHMWPE meeting at the University of Torino.

Comparison of the Wear, Wear Debris and Functional Biological Activity of Non-crosslinked and Crosslinked GUR 1020 and GUR 1050 Polyethylenes used in Total Hip Prostheses

Researchers from the University of Leeds have characterized the wear and wear particles generated from two different grades of UHMWPE acetabular cups, non-crosslinked GUR 1020 and GUR 1050, moderately crosslinked (4 MRad GUR 1020; 2.5 MRad GUR 1050) and highly crosslinked GUR 1050 (10 MRad) in an anatomical physiological hip joint simulator. The functional biological activity of the wear particles resulting from the wear tests was compared. This paper was presented on March 18, 2005, at the UHMWPE meeting at the University of Torino.
