Destruction of hip endoprosthesis due to intraarticular cement particles

In this case study of a 78-year-old female with a Hybrid-TEP prosthesis, ex tensive damage of the polyethylene inlay and strong foreign-body reaction i n 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 c up as well as the metal backing component. Wear particles from the prosthes is then can lead to unfavorable reactions within the surrounding tissue, in cluding resorption of bone in the femoral neck and consequent loosening of the implant. Critical to the success of hip prosthesis implantation is a cl ean cementing technique.
