Description

Optimizing crosslinking parameters provide X-alt highly crosslinked polyethylene with maximum wear properties while maintaining maximum strength characteristics. Biolox delta ceramic heads provide an increase in strength over traditional ceramics with approximately half the wear of a comparably sized Cobalt Chrome head. In combination, X-alt highly crosslinked polyethylene and delta ceramics provide the perfect synergy of maximum strength and minimum wear. The goal of crosslinking is to reduce wear compared to standard UHMWPE. However, too much crosslinking can affect other properties of the material. X-alt is irradiated to 7.5 Mrad, the “point of diminishing returns”, where increasing the dose no longer provides a steep reduction in wear rate.* Thus, X-alt strikes an important balance between minimizing wear and maintaining material integrity. Significantly stronger and tougher material properties make BIOLOX delta ceramic heads much more resistant to fracture, chipping and cracking. FEATURES & BENEFITS: X-alt™ crosslinking parameters provide an optimized balance between wear reduction and material strength. Lower wear means less chance for particle-induced osteolysis and subsequent implant loosening. Melt-annealed for consistent material properties over time. If not removed, free radicals can bond with oxygen, causing the material to degrade. The annealing step removes free radicals, providing stability against oxidation. Larger diameter heads increase range of motion and head “jump distance”, enhancing joint stability and helping to avoid dislocation.
