Description
本発明は、整形外科関節置換、より詳しくは骨の関節表面を再生するための整形外科関節置換において用いられる補綴装置ならびにそれを埋め込むためのシステムおよび方法に関する。
図1において示されるように、従来の関節全置換(TKA)システムには、典型的に大腿骨の遠位末端に埋め込まれて、大腿骨の軸受表面を置換する大腿骨構成要素500、脛骨の近位末端に埋め込まれて、脛骨および半月板の軸受表面を置換する脛骨構成要素502、ならびに膝蓋骨の関節表面を置換する膝蓋骨構成要素(図示せず)が含まれる。大腿骨構成要素500は典型的に、単一の固体構成要素である。脛骨構成要素502には、骨に取り付けられる脛骨ベースプレート(またはトレイ)502aおよび脛骨ベースプレート502aに配置されて、脛骨構成要素502の軸受表面を構成する脛骨インサート502bが含まれてもよい。あるいは、脛骨軸受表面は骨に直接セメント付けされてもよい。操作において、大腿骨構成要素500の軸受表面は、一連の運動の際に膝関節が動くと脛骨構成要素502の軸受表面に対して関節をなす。
本発明の一つの局面は、関節の少なくとも一部を形成するように構成された補綴装置を埋め込む方法に関する。該方法には、体に埋め込まれるように構成された補綴装置の第一の構成要素を選択する段階、第一の構成要素が体の骨に対して固定される配置を決定する段階、体に埋め込まれるように構成された補綴装置の第二の構成要素を選択する段階、および第二の構成要素が骨に対して固定される配置を決定する段階が含まれる。第二の構成要素の配置の決定は、第一の構成要素への接続に拘束されない。
本発明の現在好ましい態様を図面に示す。同じまたは類似の部品を参照するために図面を通して同じまたは類似の参照番号を用いるように努力した。
Claims (9)
- 以下の段階(a)、および(b)を含む、関節の少なくとも一部を形成するように構成された補綴装置を埋め込むためのシステムの制御方法であって、第二の構成要素の配置の決定が第一の構成要素への接続によって制約されず、かつ第一の構成要素に、脛骨の中心領域に埋め込まれた脛骨構成要素の一部を拘束するように構成された特徴が含まれる、制御方法:
(a)補綴装置の第一の構成要素が大腿骨に対して固定される配置を決定するためのコンピューターシステムにおいて、前記配置を計画するための画像データを得る段階であって、前記第一の構成要素が、大腿骨の中心領域に埋め込まれるように構成されている、段階;および
(b)補綴装置の第二の構成要素が大腿骨に対して固定される配置を決定するためのコンピューターシステムにおいて、前記配置を計画するための画像データを得る段階であって、前記第二の構成要素が、大腿骨の外側領域および大腿骨の内側領域の少なくとも一つに埋め込まれるように構成されている、段階。 - 以下の段階(a)、および(b)を含む、関節の少なくとも一部を形成するように構成された補綴装置を埋め込むためのシステムの制御方法であって、第二の構成要素の配置の決定が第一の構成要素への接続によって制約されず、かつ第一の構成要素に、大腿骨の中心領域に埋め込まれた大腿骨構成要素の少なくとも一部に対して第一の構成要素の運動を拘束するように構成された特徴が含まれる、制御方法:
(a)補綴装置の第一の構成要素が脛骨に対して固定される配置を決定するためのコンピューターシステムにおいて、前記配置を計画するための画像データを得る段階であって、前記第一の構成要素が、脛骨の中心領域に埋め込まれるように構成されている、段階;および
(b)補綴装置の第二の構成要素が脛骨に対して固定される配置を決定するためのコンピューターシステムにおいて、前記配置を計画するための画像データを得る段階であって、前記第二の構成要素が、脛骨の外側領域および脛骨の内側領域の少なくとも一つに埋め込まれるように構成されている、段階。 - 以下の段階(a)、および(b)を含む、関節の少なくとも一部を形成するように構成された補綴装置を埋め込むためのシステムの制御方法であって、第二のセグメント化脛骨構成要素の配置の決定が第一のセグメント化脛骨構成要素への接続によって制約されず、かつ第一のセグメント化脛骨構成要素の配置および第二のセグメント化脛骨構成要素の配置が、第一および第二のセグメント化脛骨構成要素が脛骨に埋め込まれる場合に、第一および第二の最低点が異なる前方-後方位置を有するように選択される、制御方法:
(a)補綴装置の第一のセグメント化脛骨構成要素が脛骨に対して固定される配置を決定するためのコンピューターシステムにおいて、前記配置を計画するための画像データを得る段階であって、前記第一のセグメント化脛骨構成要素が、第一の最低点を有する第一の外形を含む、段階;および
(b)補綴装置の第二のセグメント化脛骨構成要素が脛骨に対して固定される配置を決定するためのコンピューターシステムにおいて、前記配置を計画するための画像データを得る段階であって、前記第二のセグメント化脛骨構成要素が、第二の最低点を有する第二の外形を含む、段階。 - 大腿骨に埋め込まれる多数の大腿骨構成要素および脛骨に埋め込まれる多数の脛骨構成要素の少なくとも一つが含まれる、体に埋め込まれるように構成された複数の構成要素を含む、関節の少なくとも一部を形成するように構成された補綴装置であって、
複数の構成要素が、

複数の構成要素のそれぞれが、体の骨に対して固定されるように構成され、
複数の構成要素のそれぞれが、骨に対して構成要素を固定する配置が同じ骨に対して固定されたもう一つの構成要素との接続によって拘束されないように構成される、
補綴装置。 - 補綴装置を形成するために構成要素を接触することなく埋め込むことができるように、構成要素が構成される、請求項4記載の補綴装置。
- 脛骨構成要素の一部を拘束するための特徴に停止部材が含まれる、請求項4記載の補綴装置。
- 停止部材に凹型の少なくとも一つの表面が含まれる、請求項6記載の補綴装置。
- 脛骨の中心領域に埋め込まれるように構成された脛骨構成要素の運動を拘束するように構成された特徴に、大腿骨構成要素に配置される停止部材に接触するように構成された突起物が含まれる、請求項4記載の補綴装置。
