Cubitus varus following supracondylar fracture of the humerus in children consists of varus, hyperextension, and internal rotation deformities of the distal bone fragment of the humerus. There has been no simple clinical method of measuring internal rotation deformity. The authors report here on a method of accurately measuring the internal rotation of the shoulder in a position with the elbow at 90 degrees flexion on the back and the shoulder held at the maximum extension. When a patient with developing cubitus varus attempts to rotate his shoulder internally, there is an apparent increase in the degree of internal rotation at the shoulder of the fractured side. The mean value of the angle formed between the horizontal plane of the back and the mid-line of the forearm was approximately 0 degrees in 217 normal children, whereas an increase of 35 degrees was seen in seven children with cubitus varus. When this angle was corrected successfully, the angle after surgical correction became approximately 0 degrees. In the treatment of cubitus varus deformity, it is necessary to simultaneously correct three-dimensional deformities.
儿童肱骨髁上骨折后出现的肘内翻包括肱骨远端骨块的内翻、过伸和内旋畸形。目前尚无简单的临床方法来测量内旋畸形。作者在此报告一种在背部将肘部屈曲90度且肩部保持最大伸展的体位下准确测量肩部内旋的方法。当患有正在发展的肘内翻的患者试图内旋其肩部时，骨折侧肩部的内旋程度会明显增加。在217名正常儿童中，背部水平面与前臂中线之间形成的角度平均值约为0度，而在7名肘内翻儿童中该角度增加了35度。当该角度成功矫正后，手术矫正后的角度变为约0度。在治疗肘内翻畸形时，有必要同时矫正三维畸形。
