Description
a)自然な椎間板においては互いに独立している特に前後および外側屈曲に際して自然の椎間板によって伝達可能な層をなして重なった旋回移動が、ターニングセンタのみでの椎間板エンドプロテーゼの構成によって考慮されないこと、
b)特に前後方向の並進運動に際して、剪断運動によって、脊椎関節(ファセット関節)が負荷を受け、それによって患者の疼痛の原因となりうること、
c)2つの互いに摺動可能な関節面における不利な摩擦力が生じること。さらに、それぞれの面に消耗、すなわち、とりわけ関節部品の運動のため摩滅および抵抗が生じる。さらに、「スティックスリップ」作用が生じること、
d)機械的な椎間板代用物が関係した運動部分のさらなる変性をほとんど止めることがないこと。本来の運動関係の再現は疼痛を実質的に削減し、患者は生活の質が改善する。しかし、疼痛の新しい出現に際しては、管理の修正に取り組む必要がある。この場合、通常は、従来の構造による椎間板プロテーゼが完全に除去され、運動部分は強化される。この操作は患者にとって非常に負担となること、および
e)隣接した椎体に対する接触面の形態が通常、考慮されないこと。従来の構造の椎間板代用インプラントは平らな(フラットな)接触面を有し、これはしばしば竜骨状の***で補充されていることである。
本発明は、請求項1の特徴を有する椎間インプラントにより、かつ請求項2のステップを含んで成る椎間板インプラントによって障害のある自然の椎間板を置換する方法により上記の課題を解決する。
−前後方向および外側の旋回運動が独立していること、
−インプラントに隣接した椎体の並進運動が許されず、それによってファセット関節が保護されること、
−摩擦面が面上の転動体の移動によって最小限に削減されること、および
−関節面の摺動の代わりに転動体の回転により関節に生じる摩擦力は小さくなり、したがって、椎体の相対運動、特に脊柱の外側の曲げ、および屈曲/伸展運動が妨害されないことにおいて確認される。
転動体の数は、関節当り3〜12個、好ましくは4個でありうる。椎間インプラントの寸法によって、転動体の直径、特に球の直径は0.3mm〜6mmである。
脊柱に沿って移動する椎間板腔における自然の回転軸の異なる位置により、回転軸の配置は、斜めに、または分かれている。
さらに本発明による椎間インプラントの別の実施形態においては、腹側面から、それによって両方の部分が腹側で互いに対して一定の距離で保持される手段が両方の部分に配置されている。それによって、両方の部分が椎間腔への導入のためにしっかり保持された高さの位置へ配置可能であり、椎間腔への導入後に関節の周りで可動であり、隣接した椎体の底のそれぞれの蓋板に配置される。
本発明による椎間インプラントのさらに別の実施形態においては、両方の部分は、骨固定手段、特に骨ネジを受入れる穴を備えており、穴は中心軸に対して斜めに立っている長手方向軸を有する。好ましくは、両方の部分のそれぞれ2つの穴が腹側面から添加面に貫通する。この場合、長手方向軸は、椎間インプラントの軸固定のみがあらかじめ備えられている場合に、外側からみると中心軸に対して斜めに立ち、または椎間インプラントの角度安定固定があらかじめ備えられている場合に、やはり腹側から見ると両方の部分の内面から添加面に向かって分岐しうる。
本発明による椎間インプラントの別の実施形態においては、骨固定手段を受入れる穴は雌ネジを備えており、それによって骨固定手段の追加の堅い固定が両方の部分において達成される。好ましくは、穴は円錐状に形成されており、骨固定手段のヘッド部への雌ネジと雄ネジとの円錐状のネジ結合によって、両方の部分のそれぞれにおける骨固定手段の固定の強化が達成可能である。
添加面には、好ましくは、凸状に形成され、かつ三次元構造を、好ましくはピラミッド状の***の形で備えられている。添加面のこの構造によって、椎端板の構造が考慮される。
A)椎間インプラントの関節の1つまたは各関節を関節の1つまたは各関節の特定の位置でそのために備えられた手段によって遮断するステップと、
B)椎間インプラントを治療される椎間腔へ導入するステップと、
C)関節の1つまたは各関節を遮断するために椎間インプラントへ挿入される手段を緩めて除去するステップとを含んで成る。関節の遮断によって、外側の添加面は簡単に治療される椎間腔へ導入可能である。
本発明による方法の別の使用においては、この方法は、関節の1つまたは各関節を遮断するために備えられた手段によって移植された椎間インプラントにおける関節の1つまたは各関節の追加遮断を含んで成る。それによって、患者に術後疼痛が生じた場合、または罹患運動部分がさらに変性した場合、椎間インプラントにおける関節の1つまたは各関節が術後にそのために備えられた手段の挿入によって遮断可能である利点が達成可能である。この追加遮断は、最小侵襲的、好ましくは、腹腔鏡手術で可能である。次いで、椎間インプラントがケージの機能を担うため、脊柱の罹患運動部分は堅くなりうる。
本発明および本発明の展開を以下、多くの実施例の部分的概略図によってさらに詳しく説明する。
図1は、本発明による椎間インプラントの実施形態を示す分解図である。
図2は、図1に示された本発明による椎間インプラントの実施形態を組立てた状態で示す斜視図である。
図3は、本発明による椎間インプラントの別の実施形態を側面から見た図である。
図4は、図3による実施形態を示す斜視図である。
両方の関節38、39は3つの関節31、32、33によって実現され、それによって下関節部品33および上関節部品31がそれぞれ中央関節部品32とともに作用する関節38、39を形成する。関節38、39はそれぞれ回転軸3、4を有し、ここで回転軸は互いに垂直に、かつ中心軸2に対して垂直に立っている。下関節39は、中央関節部品32に配置され、第1の回転軸3に対して同軸の、2分軸36と、下関節部品33に配置された、軸36を受入れる2つのベアリングシェルを含んで成る。上関節38は、上関節部品31に配置された、第2の回転軸4に対して同軸34と、中央関節部品32に配置された、軸34を受入れるベアリングシェル35とから成る。ベアリングシェル35、37、および軸34、36は溝71を有し、これはそれぞれの回転軸3、4に対して直交に見た断面で回転軸3,4に対して円弧状に配置されており、転動体70として球を受入れるために役立つ。
両方の部分10、20の互いに対する可動性は、手段40によって着脱自在に遮断可能である。手段40は、ここに示されている実施形態では、両方の部分10、20の腹側面11、21から中心軸に対して斜めに、かつ両方の部分10、20の外側面13、14、23、24に対して平行に挿入可能な挿入部41を含んで成る。挿入部41の挿入は、蟻形ガイドとして形成されている2つの凹み42、43において行われる。挿入部41は、両方の部分10、20の腹側面11、21から蟻形ガイドとして構成された凹み42、43へ導入され、下部20にネジ44によって固定される。また、挿入部41は末端で凹み42、43に補助的に構成されており、両方の部分10、20は挿入部41が挿入された場合に中心軸2に対して平行に互いに対して固定される。
図4に示されている本発明による椎間インプラント1の実施形態は、穴80の長手方向軸83がさらに腹側から見ると両方の部分10、20の内面15、26から添加面15、25に向かって分岐する点でのみ図3に示されている実施形態と区別される。
