The authors' roentgenographic technique provides precise assessment of the glenohumeral relationship on the basis of two-plane examination. A group of 50 normal male subjects serve as the basis for determining normal values for the following angles or lines: projected and corrected cephalodiaphyseal angle, projected and corrected humeral retrotorsion, glenoid inclination, angle of attack, glenoid retroversion, dimension of glenoid, width of humeral head, and contact index. Two groups of patients suffering from recurrent anterior dislocation (RAD) are compared with the normal group. The shoulders with RAD do not differ significantly from the normal ones. Humeral retrotorsion, in particular, is identical. Significant differences are found between affected and unaffected sides in unilateral RAD. The diameter of the glenoid and the contact index are smaller on the dislocated side. Because the projected values seldom differ by more than 10 degrees from the calculated values, if the authors' roentgenographic technique is used, the figures can generally be accepted without correction.
作者的X线摄影技术可在双平面检查的基础上对盂肱关系进行精确评估。一组50名正常男性受试者作为确定以下角度或线的正常值的基础：投射和校正后的肱骨干骺端角、投射和校正后的肱骨后扭转、关节盂倾斜度、攻角、关节盂后倾、关节盂尺寸、肱骨头宽度和接触指数。将两组复发性前脱位（RAD）患者与正常组进行比较。患有RAD的肩部与正常肩部无显著差异。特别是肱骨后扭转是相同的。在单侧RAD中，患侧和未患侧之间存在显著差异。脱位侧的关节盂直径和接触指数较小。由于投射值与计算值的差异很少超过10度，因此如果使用作者的X线摄影技术，这些数据通常可以不经校正而被接受。
