Description
本出願は、2019年4月25日に出願された米国仮特許出願第62/838,792号の優先権および利益を主張し、参照によりその全体が本明細書に組み込まれる。
肩関節形成術は、急性変形性関節症または肩関節骨折を治療するために使用される。肩関節形成術には、全肩関節形成術(TSA)と逆肩関節形成術(RSA)の2つの一般的な形態がある。TSAは、グレノイド上のポリエチレンカップに嵌合される、金属ボール構成要素を上腕骨頭に使用する。RSAは、上腕骨がカップとなり、グレノイドが頭部となるよう、頭部とカップの間で場所を切り替える。RSAは、TSAの改訂として実施され得、それにより、回旋筋腱板損傷の患者に対してより大きな機能性が可能になる。RSAは、患者の三角筋を利用して肩の動きを制御する。
