Description
本発明は、全般的に、整形外科の分野に関し、特に、関節形成術に用いられるインプラントに関する。
骨関節症およびリウマチ様関節炎により引き起こされる疼痛および非可動化に苦しんでいる患者には、関節置換術という選択肢がある。関節置換術は、極めて一般的であり、かかる関節置換術により、多くの個々の人は、機能的な働きを適切に行うことができるが、関節置換術以外の手術では、そのようにすることが可能でない場合がある。人工関節は、通常、既存の骨に固定される金属、セラミックおよび/またはプラスチックコンポーネントで構成されている。
本発明の設計は、遠位インプラントを植え込んだ後にこのインプラントの固定位置を利用して工具を支持して近位骨を除去し、このように近位骨を除去する能力を外科医に与える。
本発明の実施形態およびその利点は、以下の説明および図面を参照すると最もよく理解される。なお、図中、同一の符号は、図面の同一および対応の部分に用いられている。
