Description
本明細書で説明するような骨プロテーゼは、骨(又は複数の骨)の少なくとも一部、及び一般に骨端の少なくとも一部を置換するように構成された、何らかのインプラントを一般に備える。したがって、インプラントは、骨端に隣接する肋軟骨下の(骨化した)骨の一部又はすべてを置換することができる。いくつかの実施例では、インプラントはまた、関節接合面を形成する軟骨を含めて、関節の関節接合面の一部又はすべてを置換することもできる。いくつかの実施例では、インプラントは、解剖学的関節を機械的関節で置換することなどにより、1つの関節の対向する関節接合面を置換することができる。
骨プロテーゼは、プロテーゼのヘッドを骨に固定するように構成された本体部分を備えることができる。本体部分は、骨内に配置され骨に固定されるステム、及び、モジュール本体構成要素によって形成される場合、別個のヘッド構成要素を係合させるための結合領域を備えることができる。いくつかの実施例では、本体部分は、骨内にステムが入ることを制限する停止部又はショルダ、並びに/あるいは、プロテーゼのヘッドをステム及び/又は骨から離隔するスペーサ領域を備えることができる。
骨プロテーゼは、対向する骨格部分と関節をなすように構成されたヘッド部分を備えることができる。ヘッド部分はとりわけ、1つ又は複数の関節接合面を有するヘッド、及び本体構成要素に係合するための結合領域又は対合構造を備えることができる。
プロテーゼの本体及びヘッド構成要素は、いかなる適当な結合機構をも用いて組み立てることができる。ここで使用される結合機構は、本体及び本体構成要素を互いに接続する何らかの機構である。
プロテーゼを、キット内に提供することができる。キットは、異なるサイズ/形状のプロテーゼ、本体構成要素、及び/又はヘッド構成要素を備え、及び/又は提供することができる。キットはまた、締結具、位置決めジグ、測定装置、ドリル、リーマ、使用説明書などを提供することができる。一部又はすべてのキット構成要素は、無菌状態で提供することができる。
骨プロテーゼは、いかなる適当な方法によっても骨(又は複数の骨)内に設置することができる。設置及び/又はプロテーゼ選択の方法に含むことができる、例示的な動作を以下に含む。操作は、いかなる適当な組合せ、いかなる適当な順番、及びいかなる適当な回数でも実施することができる。
以下の実施例は、骨端を置換するためのプロテーゼ、インプラントプロテーゼ及びその構成要素をキットから選択することを容易にするための試用プロテーゼ、並びにプロテーゼの選択及び/又は使用の例示的な方法を含めた、本願発明の教示の選択された態様及び実施形態を説明する。
軸方向アセンブリを備える橈骨頭プロテーゼ
本実施例は、軸方向に対合するヘッド及び本体構成要素を備える、例示的な橈骨頭プロテーゼについて説明する。図4〜図10参照。この例示的なプロテーゼのさらなる態様は、図1〜図3に関して上記で説明した。
本体構成要素の例示的な組
本実施例では、ステム及び/又は骨の端面からの様々な距離にヘッド構成要素を取り付けるための、本体構成要素の例示的な組を説明する(図11参照)。
傾斜したヘッドを備える橈骨頭プロテーゼ
本実施例では、固定された傾斜配置を有するヘッドを備える、例示的な橈骨頭プロテーゼを説明する(図12〜図14参照)。
ダブテイル対合構造を備える橈骨頭プロテーゼ
本実施例では、横方向運動によって本体構成要素と対合するヘッド構成要素を備える、例示的な橈骨頭プロテーゼを説明する(図15及び図16参照)。
試用プロテーゼを備えるシステム
本実施例では、(より恒久的な)インプラントプロテーゼ及び/又はその構成要素の選択を助けるために使用することができる、例示的な試用プロテーゼ及び関連機器を備えるシステムについて説明する。図24〜図29を参照されたい。
