[Histological examinations of remodelling proceedings on the cement-bone surface of endoprosthesis after implantation from 3-10 years ].
The prosthesis loosening represents the main complication of an endoprosthesis. When using bone cement for an anchorage, the most important factors of loosening are the impairment of tissue during toxical and thermic influence, foreign body reaction on the abraded material of the prosthesis, the resorption effect through foreign body giant cells as well as the parallel effect of monomer impoverishment and the dissapearance of polymerization matrix material. Histological examinations of the reparation proceedings of not loosened cement-bone surfaces at total endoprostheses are rarely found in literature, and the extent of a long term effect of the cement on the bone layer has not been sufficiently ascertained. To obtain an insight into the reaction of the bone tissue to the bone cement, the bone-cement surface was examined histologically after 3-10 years TEP-implantation.
