Abstract：
UNASSIGNED: This study aimed to determine the functional and radiographic outcomes following corrective distal humeral osteotomies for the treatment of supracondylar fracture malunions in children. We hypothesized that such secondary reconstructive procedures could restore a reasonable and near-normal amount of functionality in a large patient cohort at a tertiary referral center.
UNASSIGNED: We retrospectively reviewed the clinical and radiological records of 38 children who underwent corrective osteotomy for posttraumatic supracondylar humeral malunion using K-wire fixation. All clinical data were extracted after chart review, including age, sex, dominant side whenever available, follow-up duration, and elbow range of motion preoperatively and at the final visit. Radiographic parameters, including Baumann\'s angle, humeroulnar angle, humerocondylar angle, and elbow range of motion were evaluated preoperatively, postoperatively, and at the final visit to identify the surgical correction outcomes.
UNASSIGNED: The mean age of the patients at fracture was 5.6 (±2.7) years, and the mean age at surgical intervention was 8.6 (±2.6) years. The mean follow-up period of the current series was 28.2 (±31.1) months. Baumann\'s angle, humeroulnar angle, and humerocondylar angle were successfully restored to physiological ranges (72.6°, 5.4°, and 36.1°, respectively). Postoperatively, elbow extension improved from -22° (±5.7) to -2.7° (±7.2) versus flexion from 115° (±13.2) to 128.2° (±11.1). Three revision surgeries (8%) were encountered.
UNASSIGNED: Corrective osteotomy of the distal humerus with K-wire fixation is a reliable method to efficiently correct malunion of the distal humerus in different planes, thereby improving elbow range of motion and appearance.
UNASSIGNED: level IV: Retrospective therapeutic study.

摘要：
■本研究旨在确定矫正性肱骨远端截骨术治疗儿童髁上骨折畸形后的功能和影像学结果。我们假设，在三级转诊中心的大型患者队列中，此类二级重建程序可以恢复合理且接近正常的功能。
■我们回顾性回顾了38例儿童的临床和影像学记录，这些儿童接受了使用K-wire固定术治疗创伤性肱骨髁上畸形的矫正截骨术。所有临床资料均经过图表回顾后提取，包括年龄,性别,只要有优势，随访持续时间,术前和最后一次访视时的肘关节活动范围。射线照相参数,包括鲍曼的角度,肱骨角,肱骨髁角,术前评估肘关节活动范围，术后,并在最后一次访视时确定手术矫正结果。
■骨折患者的平均年龄为5.6（±2.7）岁，手术时的平均年龄为8.6（±2.6）岁。当前系列的平均随访期为28.2（±31.1）个月。鲍曼的角度,肱骨角,肱骨髁角成功恢复到生理范围(72.6°，5.4°,和36.1°，分别)。术后,肘部伸展从-22°（±5.7）改善到-2.7°（±7.2），而屈曲从115°（±13.2）改善到128.2°（±11.1）。3次修正手术（8%）。
■采用K线固定的肱骨远端矫正截骨术是一种可靠的方法，可以有效地纠正不同平面的肱骨远端畸形，从而提高肘部的运动范围和外观。
■IV级：回顾性治疗研究。
