1)をその内へとスライド可能に受け取る。インプラント(40”)の側面の中心部分(370)は、インプラントおよびワッシャがリング内をスライドしてある程度移動できる幅を有していることに注意されたい。
に、適切な着座の後に、インプラント(40”)を、プラスチック製の駆動ロッド(91)および小槌(95)を使用して所定位置へ運ぶことができ、また前述した実施態様に関して図13に示すように、骨セメント(300)を、インプラント(40”)の最終的着座前に導入することができ、これにより、インプラント(40”)と軟骨下骨(100)との間の接触面を強化することができる。この実施態様に関して記載されたテーパロックリング(360)やワッシャ(361)や縫合糸(363)は、インプラントへのカニューレ挿入を不要とするのでさらに取り扱いが容易となることを理解すべきである。これら構成要素は、ここで図示したように構成される必要はなく、付着性構成要素や、吸引性構成要素や、あるいは、同様な機能を果たす他の構成要素、によって代替することも可能である。
図27a〜図48は、本発明に関する他の例示としての実施形態を示している。この実施形態においては、一般的な骨インプラント(あるいは、一組をなす標準化された複数のインプラント)が、表面に対する直交軸を決定しさらに1点だけのデータポイントを採取することによって、形成される(あるいは、選択される)。上記各実施形態においては、非直交軸が使用されており、4つのデータポイントを必要として、ML曲線およびAP曲線が決定されていた。さらに、一般的な切断ツールを使用することによって、一般的インプラントが使用可能なポイントに関するサイトにおいて、骨をカットすることができる。そのようなインプラント(ならびに、上記インプラント)を使用するに際しての手順に関連したいくつかの改良されたツールについて、ここでは対応図面を参照しつつ説明する。
に際しても同一箇所において使用することができることに、注意されたい(例えば、インプラントの着座が完全ではなかった場合)。
図47,48は、キー付きとされたネジの代替可能な例示としての実施形態(720’)(図9cに示すような、ネジ(10’)のキー構造(315)を参照されたい)と、このネジと係合し得るよう構成された、キー付きとされたインプラントの代替可能な例示としての実施形態(742’)と、を示している。図に示すように、インプラント(742’)のオス型テーパー(769’)の先端部には、ネジ(720’)の対応オフセット係合部(779)に対して係合するためのオフセット係合部(778’)が取り付けられている。インプラント(742’)の係合部(778’)は、全体的に円柱形の構造とされ(さらに、丸められたまたは面取された先端部(777’)、および/または、凹所や突起といったような他の形状部分、を有することができる)、インプラント(742’)のオス型テーパー(769’)の長手方向軸からオフセットされているとともに、オス型テーパー(769’)よりも小さな径のものとされている。図48に示すように、インプラント(742’)の先端側オフセット係合部(778’)に対応した、全体的に円柱形の凹所付き係合部(779)(あるいは、例えば丸められたまたは面取された先端部(780)といったような、同様の係合用の凹所および/または突起)は、メス型テーパー(718’)の最内部分内に配置されており、メス型テーパー(718’)の長手方向中心軸からオフセットされている。ネジのメス型係合部(779)は、インプラント(742’)の先端側オフセットオス型係合部(778’)に対して係合し得るよう構成されており、これにより、ネジ(720’)内の固定位置に、インプラント(742’)のテーパー(769’)を着座させることができる。これにより、ネジ(720’)に対してのインプラント(742’)の回転を防止することができる。係合部(778’,779)と協働することにより、形成されたテーパー構造は、すべての方向において、ネジ(720’)に対してのインプラント(742’)の位置ズレを防止するよう機能することができる。本発明によるネジ(720’)は、例えば316Lステンレススチール合金やコバルトクロム合金といったようなチタン系合金から形成することができる。
図49〜図53は、二軸測定ツールを使用することによって、損傷部表面に対しての直交軸を決定するための代替可能な方法を示している。この方法は、関節表面を規定する円弧の曲率(RMLおよびRAP)が互いに相違しているような損傷部に関して、すなわち、局所的に球形ではない領域に関して、特に有効である。(これは、例えば、図29a,29bに関して上述したように、R3がR6の50%以内ではないような、場合である。)表面に対する直交軸を決定するために、二軸ツール(800)が準備される。このツール(800)は、一組をなすアーム(803)を有した外側部材(801)に対して固定された外側シャフト(805)と、この外側シャフト(805)内においてスライド可能に配置された内側シャフト(806)と、を備えている。内側シャフト(806)には、一組をなすアーム(804)を有した内側部材(802)が固定されている。外側部材(801)および内側部材(802)の各アーム(803,804)は、様々な態様とすることができる。図49〜図53に例示されたアーム(803,804)の一態様においては、各アーム(803,804)の先端部が、外向きにテーパー形状とされており、4つの接触部(808)のいずれかが連結されている。接触部(808)は、例えば図示したように、全体的にドーナツ形をなす部材(中実でもあるいは中空でも良い)からなる4つの円弧とされており、略円形の横断面を有している。(各円弧の長さは、必ずしも、互いに同じである必要はなく、例えば、図49〜図53に例示された内側部材(802)に関する接触部(808)のように、外側部材(801)に関する接触部(808)よりも、短いものとすることができる。)内側シャフト(806)は、前向きに付勢することができる。これにより、外側シャフト(805)から突出することができる、あるいは、これに代えて、スプリングによる付勢を行うことなく、手動で前進させることもできる。内側部材(802)は、外側部材(801)に対して、すべての接触部(808)が円形表面(図示せず)に対して接触するようになるまで、基端向きにまたは先端向きにスライドする。このようにして、関節表面の湾曲は、AP成分とML成分とに分離することができる。これにより、4つの個別接触点を、内側部材(802)および外側部材(801)の相
対位置に基づいて4つの接触部(808)から外挿することができ、損傷部表面に対する直交軸を、決定することができる。ツール(800)のシャフトは、カニューレ付きのもの(図示せず)とすることができる。これにより、ガイドピンまたはワイヤ(または、穿孔ツール)を、関節表面内へと、図27a〜図31に関連して上述したように、貫通させつつ案内することができる。図53に示すように、内側部材(802)と外側部材(801)とが、4つの接触部(808)が完全なドーナツ形すなわちリングを形成するようにして、互いに配置されたときには、関節表面は、局所的に球形であることになる。すなわち、(図49に示すように)RMLおよびRAPが互いに等しい。したがって、二軸ツール(800)を使用する必要はない。
図54〜図61は、本発明に基づくデジタル測定システムの一例を示している。図示したように、このシステム(810)は、ケーブル(813)を介してハンドピース(812)に対して連結されたベースユニット(811)を備えている。詳細に後述するように、ベースユニット(811)は、シャシー内にあるいはシャシー上に、引裂ストリップ(814)を有することができる。これにより、測定データを記録したプリント済み紙テープを切り取ることができる。このようなシステムは、本発明の実施に際し、外科手術ミスや他の人的ミスに関する潜在的リスクを低減あるいは除去することができる。
