[Ceramic cups for hip endoprostheses. 4: Never mix and match].
Femoral ball heads for total hip replacement are made of various materials, e.g. cobalt chrome alloy, coated metal, or various ceramics. Standard sockets are made of polyethylene, alumina ceramics, or CFRP. Due to tribological reasons some of the combinations of head and socket that seem possible are prohibited. The approved and prohibited combinations are reviewed and reasons for not approving are discussed.
