Abstract
Description
本発明は、二つの短側および二つの細長側を形成して貫通路を有する概ね細長い構造を画定する壁を含む脊椎インプラントを提供する。前記インプラントを設置する背骨の運動により前記インプラントに加わる力によって、二つの前記細長側の少なくとも一つの細長側は前記貫通路へ弾性圧縮可能、または前記貫通路から離れる方向へ弾性膨張可能である。圧縮可能な少なくとも一つの前記細長側は前記力が除去されるときに静止位置に復帰移動可能である。
本発明は、二つの短側および二つの細長側を形成して貫通路を有する概ね細長い構造を画定する壁を含む脊椎インプラントを提供する。前記インプラントを設置する背骨の運動により前記インプラントに加わる力によって、二つの前記細長側の少なくとも一つの細長側は前記貫通路へ弾性圧縮可能、または前記貫通路から離れる方向へ弾性膨張可能である。側の精確な運動は、背骨の特定の物理的運動に依存する。背骨の付勢に対向する弾性は、運動が弛緩した後に装置を静止位置へ復帰させ、それにより背骨を通常位置へ復帰させ、それにより背骨を適正に整列させる。好適には、装置は、前記壁により形成された概ねループ形態の可撓性本体を含み、前記壁の材料および厚みは、装置が適宜程度の可撓性および強度を有するように選択される。
