Abstract
【解決手段】 外科医が数種類の遠位大腿骨インプラント構成部品及び数種類のステム延長部から選択できると共に骨幹端構成部品を使用することができるモジュラー膝インプラントシステム。骨幹端構成部品は、アダプターを用いてあらゆる種類の遠位大腿骨インプラント構成部品と使用できる汎用部品とすることができる。第2のアダプターにより、別の種類のコネクタを備えたステム延長部を骨幹端構成部品と共に用いることができる。別の骨幹端構成部品に、近位モールステーパー孔を備えた遠位大腿骨構成部品に一致する遠位モールステーパーポストを設けることもできる。骨幹端構成部品は、患者の骨との接触領域を最大にするように構成された外面を備え、骨の成長を促進する表面仕上げをほぼ全長に亘って有し得る。
