Advanced Machining of Joint Implant UHMWPE Inserts

The modern orthopaedic implants for applications in hips, knees, shoulders, and spines are composed of hard metal alloys or ceramics a tribological sub-component that is made soft materials, with good frictional properties—e.g., UHMWPE (Ultra High Molecule Weight Polyethylene). need to be machined into their final shape after the polymerization consolidation blank profile near net shaped implant. Thus, machining crucial technology can generate an accurate precise implant should comply joints’ function. However, affect topography integrity surface, transmitted stresses, resistance wear. Technology, cutting tools, conditions have impact on physical mechanical properties entire its longevity. This paper shows effective competitive acquiring high-quality insert shape, dimensions, needed especially customized implants.
