To determine the effects of limb positioning on Baumann's angle, we made a controlled radiographic study of a 6-year-old cadaver upper extremity specimen. Radiographic measurement of Baumann's angle was obtained at 10 degrees increments of humeral rotation from 40 degrees of internal rotation to 40 degrees of external rotation. These measurements were obtained with the humerus parallel to the x-ray cassette and with the humerus flexed 30 degrees from the cassette. Measurement of Baumann's angle with radiographs obtained with the humerus parallel to the x-ray cassette was associated with less variation in the measured angle (6 degrees of change for every 10 degrees of rotation). The relevance of these findings in management of supracondylar fractures is discussed.
为确定肢体位置对鲍曼角的影响，我们对一具6岁尸体的上肢标本进行了对照放射学研究。在肱骨从内旋40度到外旋40度以10度增量进行旋转时，对鲍曼角进行放射学测量。这些测量是在肱骨与X线暗盒平行且肱骨相对于暗盒屈曲30度的情况下进行的。使用肱骨与X线暗盒平行时获得的X线片测量鲍曼角，所测角度的变化较小（每旋转10度变化6度）。讨论了这些发现对上髁骨折治疗的相关性。
