Abstract
Description
本発明は、肩関節のための全補綴物に関する。それは、上腕骨における凹状部材と肩甲骨上の凸状部材とを伴ういわゆるリバース型のものである。
全肩関節形成は、現在最も急速に発展する関節置換である。これは、部分的には、インプラントの臨床上の性能の向上によるものであるが、しかし、リバース型の補綴物がますます容認されていることによる。解剖学型の補綴物においては、上腕骨頭が、もっとも典型的には上腕骨の幹の近位端に置かれる、同様の大きさと形をした補綴物のヘッドと置き換えられる。関節窩は、自然的な関節窩にとても類似した形のインプラントによって置き換えられ、一般にスクリューによって固定され、そして、二次的な骨成長に適合する。
本発明はリバース型の全肩補綴物を開示する。上腕骨頭の切除面の下において近位の上腕骨に固定される凹状部材は深いカップであり、肩甲骨に固定される補綴物のヘッドの約180°またはそれ以上、例えば、約180°から約200°をカバーする。それは、全臀部補綴物の寛骨臼のカップにとても類似し、好ましくは、リーミングによってできる網状構造の骨の土台に圧入によって固定され、続いて、骨成長による二次的な安定化が生じる。
(i) 近位の上腕骨への取り付けに適した凹状部材300、および、
(ii) 球状のヘッド200と肩甲骨への取り付けに適した骨アンカ100を含む凸状部材
とを備え、
ここで、前記凹状部材300は前記球状のヘッド200を受けるのに適した凹所301を備え、
そして、ここで、前記凹状部材300は、前記球状のヘッド100の少なくとも180°のカバレッジを提供する、
補綴物、
に関する。
それは、前記ヘッドを少なくとも180°、好ましくは、さらに約190°または約200°まで、カバーし、脱臼をより防ぎつつ、同時に、衝撃のない十分な動作範囲を伴う。前記カップのボディ302は、ポリエーテルエーテルケトン(PEEK)などの生体適合性のポリマーから作られてもよく、前記ヘッドとの環状の接触部位において、強化材料から作られたリング303、特に、強化PEEKリング、例えば、カーボンファイバーで強化されたPEEKリング303を備えてもよい。セラミックのヘッドと関節接合する際のこのリングの摩耗は極めて低い。前記カップの裏側、すなわち、前記凸状部材に対して遠位側は、チタンおよび/またはハイドロキシアパタイトの多孔のレイヤーによってコートされていてもよい。放射線による特定のため、前記カップは、放射線に関するタグ、例えば、赤道上のメタルリング304を備えてもよい。
軽微な手術によって関節窩の端のちょうど上で関節窩の背後の骨を露出させることは、正しい方向を見出すのに有用であり得る。関節窩に対して約90°を狙うという別の方法もある。
