Description
図14および図15を次に参照すると、組立て時の本発明の手首プロテーゼ(1)の手根骨構成要素(200)、月状骨構成要素(300)、および橈骨構成要素(100)の横断面図が示されている。留意されるように、手根骨構成要素および月状骨構成要素を組み立てるために、月状骨構成要素(300)の空洞(302)の球形領域(304)の口(308)は、手根骨構成要素(200)のボール端(222)の直径(223)より狭いため、ボール端(222)は、定位置にパチンと嵌るまで、空洞(302)内へ押し込まなければならない。すなわち、月状骨構成要素は、一時的に変形するがすぐにその元の形状に戻り、ボール端(222)をその空洞(302)内に保持する。しかし、定位置に入った後、月状骨構成要素は、手根骨構成要素に対して固定して保持されるが、2つの構成要素は、互いに対して自由に回転および旋回する。
罹患した手首および皮膚の背側に長手方向に切開部が形成され、筋肉および腱が後退させられて、手根骨および橈骨の遠位端が、その関節面を含めて露出される。
月状骨構成要素(300)、手根骨構成要素(200)、および橈骨構成要素(100)はそれぞれ、任意選択で、1つまたは複数のサイズで提供される。各構成要素の適切なサイズは、患者の解剖学的構造によって決まる。任意選択で、この適切なサイズ設定は、それらの構成要素のそれぞれの様々なサイズの同等のモデル化版(図示せず)を選択して事前に組み立てることによって、手術中に実現してもよい。
位置合わせに関して残っているあらゆる問題が外科医によって補正され、満足のいく運動範囲が実現された後、標準的な外科的技法を使用して、切開部が閉じられる。
