Abstract
【解決手段】椎弓形成術プレートは、脊柱管に対して望ましい間隔を維持するために、分割された椎弓板の少なくとも一部分に係合可能である。椎弓形成術プレートは、少なくとも1つの分割された椎弓板部分によって形成された隙間に架ける第1端部と第2端部とを有するスペーサ部分810を含んでいる。椎弓形成術プレートは、分割された椎弓板部分との係合のために、一方の端部に椎弓板係合部分815を含んでいてもよい。
【選択図】図8
Description
毎年、多くの人が外傷による頚部、背部、及び/又は脊椎の重大な損傷に苦しんでいる(人の典型的な脊柱については、頚部110、胸部120、腰部130、仙骨140、及び尾骨150の部位を含む図1の斜視図の脊柱100を参照のこと)。それら損傷としては、頚部骨折、骨折転位と円板の後方突進との合併症、及びその他主要な損傷を挙げることができる。更に、毎年、多くの人々が変性疾患、特に変性脊柱管狭窄症の手術を受けている。脊柱管狭窄症では、脊髄及び神経根が中に入っていてそれらを保護している脊柱管が狭くなり、その結果、脊髄と神経が圧迫されることになる。外科処置の目的には、脊柱の圧迫された全てのレベルに減圧を施してしっかりとした固定(Solid Fusion)で安定を図ることが挙げられる。
本発明の原理の理解を促すことを目的として、これより図面に示す実施形態を参照してゆくが、説明に当たっては特定の言語を使用する。但し、それにより本発明の範囲を限定する意図はない。記載の装置に加えられるあらゆる変更及び修正、及びここに記載する本発明の原理のこの他の適用の全てについては、本発明が関係する分野の当業者であれば普通に考案できるものと考えられる。
