The transepicondylar axis of different position has no effect on volume rendering technique measuring the humeral head retroversion angle with multi slice spiral CT.The top view at which lateral epicondyle of the humerus showing minitriangulum and the anterior surface of the distal humerus articulation with the forearm being shaded is more simple,faster and precise for the volume rendering technique measuring the humeral head retroversion angle with multi slice spiral CT.

结论］肱骨头扭转角变异较大，肩关节假体扭转角设计应个性化；肱骨远端不同位置内外上髁轴线对多层螺旋CT容积再现测量肱骨头扭转角没有影响；俯视位观察肱骨，当外上髁露出呈小三角形、肱骨远端前关节面被肱骨头遮盖重叠的位置是多层螺旋CT三维重建测量肱骨头扭转角的更简单、更快捷而且准确的测量位置。
