Distal humeral extension-type malunions may occur as a complication following improper reduction of supracondylar humerus fractures. We evaluated results after distal humeral flexion osteotomies for sagittal realignment of the humeral condyle in children. Medical records and radiographs of all patients younger than 18 years of age, who underwent this procedure because of a clinically relevant lack of elbow flexion, were evaluated. In a cohort of 18 children with a mean age of 8 years at the time of surgery and a mean follow-up duration of 1 year, elbow flexion increased significantly from a mean of 101° preoperatively to 126° at the final follow-up; established radiographic parameters (e.g. anterior humeral line, humerocondylar angle) were normalized as well. The distal humeral flexion osteotomy is a reliable method to efficiently correct extension-type malunions and improve impaired elbow flexion in children.
肱骨远端伸展型畸形愈合可能作为肱骨髁上骨折复位不当后的一种并发症出现。我们评估了儿童肱骨远端屈曲截骨术用于肱骨髁矢状面重新对线后的结果。对所有因临床相关的肘关节屈曲功能缺失而接受该手术的18岁以下患者的病历和X线片进行了评估。在一组18名儿童中，手术时平均年龄为8岁，平均随访时间为1年，肘关节屈曲角度从术前平均101°显著增加到最终随访时的126°；既定的影像学参数（如肱骨前线、肱骨髁角）也恢复正常。肱骨远端屈曲截骨术是一种有效纠正伸展型畸形愈合并改善儿童受损肘关节屈曲功能的可靠方法。
