Metall-Metall-Totalprothese des Hüftgelenkes: Zurück in die Zukunft
2008
Late loosening in total-hip-replacement is explained by a foreign body reaction of the connective tissue along the bone-implant interface due to polyethylene debris. In contrast, metal-metal-prostheses, implanted in the sixties, may still today work perfectly without any signs of osteolysis along the bone-cement interface, proving, that metal-metal-pairing is superior to prostheses with polyethylene cups and that cement-anchorage may also be adequate for fixation. A new metal-metal-total hip-joint is presented, that has been implanted from 1988-1990 62 times.
