Outline of Research at the Start

2014年より反転型人工肩関節が本邦でも使用できるようになり、その使用頻度は増加している。本邦で行われている人工肩関節置換術の9割が反転型である。単純X線でどの程度上腕骨を延長するかを計測することができる一方、三角筋の延長や緊張をどの程度にするか術前に決める方法はない。本研究ではひずみセンサーならびに超音波エラストグラフィを使用し三角筋の長さと緊張を新鮮遺体肩を用いて評価する方法を確立することを第一の目的とし、次に術後良好な可動域獲得のために適した至適な長さと緊張を求めることを調査することである。

Outline of Final Research Achievements

By using fresh frozen cadaveric shoulders, we measured the elasticity of the deltoid muscle with use of ultrasound elastography. Also, we measured the strain of the deltoid using micro strain sensor (DVRT sensor). Our data showed that the appropriate land mark was demonstrated to the acromion, coracoid process, and scapular spinatus. We could confirm that we were able to measure in the various arm positions.

Academic Significance and Societal Importance of the Research Achievements

近年、反転型人工肩関節置換術は本邦でも広く行われるようになってきている。その特徴は肩関節の回転中心を内側かつ遠位に変位させて、挙上を可能にする仕組みとなっている。しかし、どの程度、内側、遠位に変位させるかは術者によって異なっている。本研究によって、どの程度、遠位に変位させるかの指標となる数字が得られた。
