Abstract
Description
本発明は股関節の再構築に関するものであり、特に股関節を再構築する関節形成術用の大腿骨部品に関するものである。しかしながら、本発明は股関節の再構築に限定されるものではなく、人間及び他の哺乳動物における別の球窩関節に応用して利用することができる。
股関節を再構築する概念は、1950年代の後半以来知られている。股関節の再構築は、骨の大部分を完全に削除するのではなく、衰弱した、又は病変した股関節の範囲内で骨表面だけを置換することが好ましいという事実に頼っている。このアプローチは、大腿骨の頭部及び頚部を保存するという利益を有する。これは、完全な股関節の自然なオフセット及び前傾を残し、ほぼ同等の脚の長さを維持する。球窩関節におけるより大きなサイズの球は、脱臼の問題を減少させる。骨の上に負荷されるストレスは比較的自然である。さらに、磨耗率が低い金属を使用することができる。
第1の態様によれば、本発明は、大腿骨キャップ及び軸を含む、股関節を再構築する関節形成術用の大腿骨部品であり、上記大腿骨キャップは骨盤骨の中にセットされるカップと噛み合うように適応され、上記大腿骨キャップは凸状の表面及び凹状の表面を持ち、上記軸は上記大腿骨キャップの凹状の表面に取り付けられ、少なくとも上記軸の一部が可溶性の材料で構成されることで特徴付けられる。
本発明の好ましい実施形態は、現時点では、以下の添付の図を参照して、実施例のみを通じて記述されるだろう。
図1〜3を参照しながら、ヒトの股関節を再構築する関節形成術用の大腿骨部品1を説明する。大腿骨部品1は凸状の表面4及び凹状の表面5を持つ大腿骨キャップ2を含む。大腿骨キャップ2はカップ3と噛み合うように適応される。大腿骨キャップ2及びカップ3は鋼のような金属で構成される。
