Numerous small scratches and some larger scratches have been observed on metallic femoral heads of explanted hip prostheses, with the larger scratches believed to be a major contributor to increased wear of the polyethylene acetabular cups. Previous work in our group has shown that smaller scratches, with a mean lip height up to 0.35 microm, can be caused by bone cement and bone particles up to 500 microm in size. However, the larger scratches were not readily replicated with these particles… CONTINUE READING
