摘要: The mechanism of initiation loosening cemented femoral components is now known. It debonding at the cement-metal interface. Current data strongly support concept that a collar and improvement interface are valuable. Precoating having roughened surface proximally distally on stem contribute to extended longevity Using contemporary instrumentation, collar-calcar contact can be achieved regularly and, once achieved, well maintained for years.
