ことを特徴とする股関節内プロテーゼシステム。 - 請求項1〜4のいずれか1項記載の股関節内プロテーゼシステムであって、
ソケット(1)とインレー(2)との間の運動が、1つ以上の溝(22)に係合する1つ以上の案内/止め(12)により、強制的にロックし重なり合うやり方で1つの中心線及び回転に限定され、上記インレー(2)は生理的可動域の範囲内でもはや上記ソケット(1)から転位することができないことを特徴とする股関節内プロテーゼシステム。
逆に、上記インレー(2)に上記案内(12)を設置することができ、上記ソケット(1)に上記溝(22)を設置することができる。また、ソケット(1)及びインレー(2)の、インレー(2)と頭部(3)との間の運動に対して案内される運動を相応に再配置することが可能である。 - 請求項1〜5のいずれか1項記載の股関節内プロテーゼシステムであって、
極端な偏位の場合のみに、ソケット(1)とインレー(2)との間の運動、又は頭部(3)とインレー(2)との間の運動が、1つ以上の溝(22)に係合する1つ以上の案内/止め(12)により限定され、前記インレー(2)は端部止めにてもはや前記ソケット(1)から転位することができないが、生理的可動域の範囲内で幾つかの中心線及び回転が自由であり、ただし完全な回転は回避されることを特徴とする股関節内プロテーゼシステム。
ここで、ソケット(1)、インレー(2)、及び頭部(3)の球状中心は、上記インレー(2)自体が心合わせするように構成することができる。対応する可動域が可能である場合、上記インレー隆起部(25)は半径方向で封入する形態とすることもできる。 - 請求項1〜6のいずれか1項記載の股関節内プロテーゼシステムであって、
上記ソケット(1)が1つ以上のボアホール/受け器(13)を含み、該ボアホール/受け器が、ねじ(7)によって根本的に固定するように、又は上記案内/止め(12)を取り付けるように働くことを特徴とする股関節内プロテーゼシステム。上記ねじ(7)と案内/止め(12)とを組み合わせることも可能である。上記案内/止め(12)により、それら自身の中心線の周りの(部分)回転を可能にすることができる。上記骨に更に固定するために、上記ソケット縁部に付加的な掛け金又はボアホールを提供することもできる。 - 請求項1〜7のいずれか1項記載の股関節内プロテーゼシステムであって、
上記インレー(2)が、基本インレーユニット(28)と1つ以上の閉鎖部(29)とから成り、手術中の再配置後に、該閉鎖部が例えば、強制ロック突出部(281)及び強制ロック溝(291)による強制ロック結合を介して、又はねじ山(282)及びねじ(292)によって、上記基本インレーユニット(28)に固着されることを特徴とする股関節内プロテーゼシステム。相応に構築される場合、上記閉鎖部(29)は吸収性材料製とすることもできる。 - ソケット(1)、インレー(2)、頭部(3)、別個の頸部(4)、及び軸(5)から成る股関節内プロテーゼシステムにおいて、
上記頸部(4)は、上記頭部(3)の上記円錐体受け器(31)と同様に、近位に従来の円錐体(41)が、遠位に軸結合部(43)が形成され、該軸結合部が、円錐体受け器、ねじ結合、あるいはその他の或る強制ロック結合のいずれかとして形成されることを特徴とする股関節内プロテーゼシステム。
ここで、上記頸部(4)はCCD補正角(ε)を有することができ、軸方向回転防止受け器(44)ならびに回転防止ピン(54)により、上記軸(5)上での上記頸部(4)の回転を防止することができる。上記軸(5)の前捻/後捻を補償するために、幾つかの回転防止受け器(44)及び回転防止ピン(54)、又はその他の或る結合要素を提供することもできる。上記軸結合部(43)がねじ結合として構築される場合、回転はロックナット(6)又はその他のねじロック機構によって防止することができる。 - 請求項9記載の股関節内プロテーゼシステムであって、
上記軸(5)は近位内方に適合面(52)を有し、該適合面は、この領域において上記軸(5)を短縮するようにも働くことができ、これによりモジュール式頸部(4)の使用が可能となることを特徴とする股関節内プロテーゼシステム。上記軸の基本形状は、実質楔形の形態で、水平面ではテーパ角(π)にて、矢状面ではテーパ角(ρ)にて、上記先端(58)まで先細にすべきであり、近位内方には湾曲(57)を設けることができる。上記頸部結合部(51)は、請求項9記載の上記軸結合部(43)と同様に形成される。請求項9と同様に、1つ以上の回転防止ピン(54)又は回転防止受け器を提供することができる。 - 請求項9又は10記載の股関節内プロテーゼシステムであって、
