A study correlating the degree of medial rotational deformity of the distal humerus and the degree of cubitus varus deformity secondary to supracondylar fracture was performed in 23 patients who underwent corrective supracondylar osteotomy. The mean age of the patients at the time of operation was 10.9 years (range 5-14 years). The time interval from injury to operation averaged 3.2 years (range 1-6 years). A medial rotational deformity occurred in 20 cases. The degree of medial rotational deformity (MRD) averaged 16.2 degrees (range 0-34 degrees). Mean carrying angles (CA) of the deformed and normal sides were -19.6 degrees and 6.5 degrees, respectively. Mean humero-elbow-wrist (HEW) angles, measured from radiographs, of the deformed and normal sides, were -18.8 degrees and 7.7 degrees, respectively. There was no correlation between the degree of MRD and the degree of varus deformity, using as a comparison either the CA or the HEW angle of the deformed elbow or their differences from the normal side.
对23例行髁上截骨矫正术的患者进行了一项研究，该研究将肱骨远端内旋畸形程度与髁上骨折继发的肘内翻畸形程度进行了关联分析。患者手术时的平均年龄为10.9岁（范围5 - 14岁）。受伤至手术的时间间隔平均为3.2年（范围1 - 6年）。20例出现了内旋畸形。内旋畸形（MRD）程度平均为16.2度（范围0 - 34度）。畸形侧与正常侧的平均提携角（CA）分别为-19.6度和6.5度。从X线片测量的畸形侧与正常侧的平均肱骨-肘-腕（HEW）角分别为-18.8度和7.7度。使用畸形肘的CA或HEW角或它们与正常侧的差异作为比较，MRD程度与内翻畸形程度之间无相关性。
