Total Hip Joint Replacement Using a CoCrMo Metal-Metal-Sliding Pairing.
- Orthopädie und Klinik am Rosenberg, St. Gallen, Switzerland.
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 of the McKee type implanted in the sixties, may still work perfectly today without any signs of osteolysis along the bone-cement interface, providing that metal-metal pairing is superior to prostheses with polyethylene cups and providing also that cement anchorage may be adequate for fixation. A new metal-metal total hip joint is presented, that has been implanted 62 times between 1988 and 1990. Key words: total hip replacement, metal-metal pairing.
