The angle of humeral torsion may be determined in living subjects by computerised axial tomography, in conjunction with immobilisation of the arm on a rigid board. Transverse scans of each humerus through the proximal and distal ends were obtained in 28 control subjects. The mean angle of torsion was found to be 62.8 degrees with a range of 40 degrees (minimal value 42 degrees, maximal value 82 degrees). These figures were comparable to results obtained by other authors. The wide spread of the measured values allows the clinical application of the humeral torsions exclusively in relation with the contra-lateral side for preoperative planning.
肱骨扭转角度可通过计算机断层扫描在活体受试者中确定，同时将手臂固定在硬板上。对28名对照受试者的每根肱骨近端和远端进行横向扫描。发现平均扭转角度为62.8度，范围为40度（最小值42度，最大值82度）。这些数据与其他作者获得的结果相当。测量值的广泛分布使得肱骨扭转仅在术前规划中与对侧相关时才可临床应用。
