Abstract
Description
骨由来のインプラントは、人間及び動物の整形外科的治療におけるさまざまな医療上の困難に対処するために幅広く使用されてきた。そのようなインプラントの使用は既に、例えば、美容及び、再建外科、歯科再建外科、足病学、整形外科、神経外科、並びに硬組織を含む他の医療分野へも普及している。(患者から移植源が提供される)自家骨、(同種間の他の個体から移植源が提供される)同種骨又は(異種間の他の個体から移植源が提供される)異種骨の使用は、人間医学及び獣医学の両方で周知である。特に、移植された骨を使用して、支持し、治癒を促進し、骨の空間を充填し、骨要素(椎体など)を隔離し、固定を促進する(骨同士が互いに成長して単一の密な単位になるように誘導する)又は骨折部位を安定させることが周知である。最近では、処理した骨を、新しい外科的適用に使用するための形状にする、又は以前は非生体由来材料を使用していたインプラントのための新材料とする、などの開発が進められている。
本発明の目的は特に、細長い骨粒子の凝集性の集合体から構成される所定の形状及び寸法の骨インプラントを提供することである。
本発明の更に別の目的は、上述の特徴を有する骨インプラントの製造方法を提供することである。
本発明の他の特定の目的は、例えば側湾症を治療するための固定術などの脊椎固定術において、ストリップの形態の骨インプラントの提供、及びストリップの使用を含む。
更に本発明の別の特定の目的は、溝形の骨インプラントの製造方法の提供である。
本明細書で使用される用語「同種移植」は、対象となる被移植者と同種の別の個人から採取した、移植を目的とする組織のことを言う。
表現「脱無機質化骨」は、部分的、全体的、区画的、又は表面的(表面)に脱無機質化した骨を含む。
骨プラグ及び/又はその細長い骨粒子成分に適用される用語「骨原性」は、骨インプラントが、例えば骨形成、骨伝導及び/又は骨誘導など、1つ又は複数のメカニズムによって、新しい骨組織の成長を容易にし、又は促進する能力のことをいうものであると理解される。
本明細書で使用される用語「デバイス」は、主に非骨材料から作製される任意の骨インプラントのことをいうものである。このようなデバイスは一般に、例えば外科用バイオグラス(Bioglass)(登録商標)などの生体適合性金属、例えば生体適合性ポリマー材料、例えばポリ乳酸、ポリテトラフルオロエチレンなど、又は他の適切な生体適合性非骨材料など、生体適合性インプラントの製造に広く使用されている材料から作製される。
骨インプラントの一実施形態を構成する細長い骨粒子の凝集性の集合体に適用される用語「開口性の細孔構造」は、集合体の全容積を通して見られる出入り可能な複数の孔又は開口を有する骨インプラントの、低密度、吸収性、スポンジ様の性質のことをいうものと理解されたい。
適切な生物静力学剤/殺菌剤には、抗生物質、ポビドン、糖、ムコ多糖体などがある。
実施例1のストリップ形状の骨インプラントの作製に使用する細長い骨粒子の約200g〜約300gを、細長い骨粒子1グラムあたり約5ml〜約15mlのグリセロール、細長い骨粒子1グラムあたり約5ml〜約20mlの蒸留脱イオン水と均一に混合し、1〜8時間膨張及び水和させてスラリーを形成する。任意で、グリセロール、水の一方又は両方を加える前に、細長い繊維を摩砕又は細断し、全体的な寸法の1つ又は複数を減少させることができる。更に任意の処置として、グリセロール、水の一方又は両方を加えた後で、細長い繊維を練合し、混合し、粉砕し、又は細断する。スラリー及び混合物から余剰液体を排出し、その後従来の凍結乾燥条件下で凍結乾燥する。結果として生じたパテ様の骨インプラント材料を保存及び/又は出荷のために無菌包装する。
骨インプラント20は一般に矩形の形状を有し溝状の矩形陥凹部21で特徴付けられる。多量のこのような骨インプラントを、図5に示す型30、図6に示すカセット40、及び図7に示す蓋50を使用して簡便に形成することができる。
