Abstract |
健常肩関節の形態を評価した報告は数少なく, 特にアジア人を対象にした詳細な研究は未だなかった。本研究は健常日本人の肩関節形態をCT画像で調査および解析することにより, 関節置換および関節形成の治療成績向上に貢献することであった。
80名160肩の健常日本人に対して撮影された両側肩甲帯単純CT画像を三次元解析し, 肩甲骨および上腕骨のサイズおよび方向を評価した。男性・女性ともに値は比較的均一であったが, 過去の欧米における報告に比べて上腕骨頭および関節窩ともに全てのパラメーターが小さな値を示していた。このことより既存のインプラントでは日本人女性には対応しない可能性が示唆された。
An understanding of normal glenohumeral geometry is important for anatomical reconstruction in shoulder arthroplasty. Unfortunately, the details of the glenohumeral joint in Asian populations have not been sufficiently evaluated. The purpose of this study was to evaluate the 3-dimensional geometry of the glenohumeral joint in the normal Japanese population and to clarify its morphologic features. Anthropometric analysis of the glenohumeral joint was performed using computed tomography scans of 160 normal shoulders from healthy Japanese volunteers. The values of the glenohumeral dimensions were uniform in men and women. The glenohumeral size was well correlated between the 2 sides, and there were direct correlations among the heights, humeral length, humeral head size, and glenoid size. The present results would be useful to determine the size of implants and to improve the design of shoulder prostheses that reflect the normal anatomy of the Asian glenohumeral joint.
