[Destruction of the gliding inlay of a hip endoprosthesis caused by intra-articular cement particles].
In this case study of a 78-year-old female with a Hybrid-TEP prosthesis, extensive damage of the polyethylene inlay and strong foreign-body reaction in the neighboring soft tissue were seen four years following implantation. The introduction of just a few cement particles during implantation of hip prosthesis may lead to considerable damage of especially the polyethylene cup as well as the metal backing component. Wear particles from the prosthesis then can lead to unfavorable reactions within the surrounding tissue, including resorption of bone in the femoral neck and consequent loosening of the implant. Critical to the success of hip prosthesis implantation is a clean cementing technique.
