Description
・前記チューブを一定期間硬化し、
・前記チューブに対し適切な解剖学的形態を賦与し、
・術後初期の、移植骨の散逸を避けるために、移植骨の移動に対して前記チューブを密閉する、
ことが可能となる。
プレート3は前記チューブ1の長さに沿って適合され、前記プレート3は、部分的な椎体の切除を受けた上方および下方の各々の脊椎にネジ固定されている。プレート3はその両端を緊締ネジ4により該位置に保持され、ネジ4は二つの健康な脊椎Vに固定される。前記移植骨が、少なくとも一つのネジ5により、本例ではその中央部で、プレート3に連結される。本発明によれば、広幅メッシュ6は、一定期間の後に、前記移植骨の成長を可能にするために消滅する。また本図面においては、脊椎の横断方向および棘突起(言及しない)が示されている。図2は、椎体V1の断面内で所定位置に設置された移植組織の頭上方向からの図示である。本図においては脊柱管(言及しない)が模式化されている。プレート3の中央には、チューブ1を貫通し、チューブ1の所定位置の保持を支持して移植骨内に固定されたネジ5が示される。
疑いなく、種々の変形形態、特に代替物による同等の技術手段によって実施される変形形態は、本発明の適用範囲に含まれるものである。

Claims (5)
- 外傷を受けた骨に対する、関節固定術による骨修復手段において、生体吸収性または非吸収性の、生体適合性の広幅網の網目繊維素材からなる柔軟なチューブ(1)を備え、このチューブ(1)は生体吸収性の被覆素材で被覆されて、一定期間硬化されており、その内部に移植骨(2)が挿入されることを特徴とする骨修復手段。
- 請求項1の骨修復手段で、チューブ(1)が、ネジ(4)により健康な各骨部(V)に固定されたプレート(3)により、所定位置に保持されることを特徴とする骨修復手段。
- 請求項2の骨修復手段で、チューブ(1)がまた、端部が移植骨(2)中に埋め込まれた少なくとも一つのネジ(5)により、保持されることを特徴とする骨修復手段。
- 請求項1から3のいずれかの骨修復手段で、前記移植骨(2)が、圧着湿布様の骨片および/または骨代替物の構成からなることを特徴とする骨修復手段。
- 請求項1から4のいずれかの骨修復手段で、生体吸収性の被覆素材がポリ‐L‐乳酸、および/またはポリグリコール酸および/またはそれらの共重合体であることを特徴とする骨修復手段。
