To report our method of computer-planned rotational corrective osteotomy for malunited distal diaphyseal radius fractures in children and adolescents using a custom jig and to review the results of 4 cases.
Four patients (mean age, 13 years; range, 11-16 years) underwent computer-planned rotational corrective osteotomy for malunited distal diaphyseal radius fracture using a custom jig. We retrospectively evaluated their radiographic and clinical data.
In patients who had marked restriction of forearm supination before osteotomy, the mean arc of forearm supination improved from 5° before surgery to 79° after surgery. Angular deformity on x-ray, range of forearm rotation, and grip strength all improved after surgery. Mild and moderate pain reported by 1 and 2 patients, respectively, was resolved after surgery.
Computer-planned rotational corrective osteotomy for malunited distal diaphyseal radius fracture in children and adolescents using a custom jig is a strategy that facilitates the surgical procedure by accurately correcting both rotational and angular deformities on 1 plane in a single procedure.

报告我们使用定制夹具对儿童和青少年桡骨远端骨干骨折畸形愈合进行计算机辅助计划旋转截骨矫形的方法，并回顾4例患者的治疗结果。
4例患者（平均年龄13岁；范围11 - 16岁）使用定制夹具对桡骨远端骨干骨折畸形愈合进行计算机辅助计划旋转截骨矫形。我们回顾性评估了他们的影像学和临床资料。
术前前臂旋后明显受限的患者，前臂旋后平均弧度从术前的5°改善至术后的79°。术后X线显示的角畸形、前臂旋转范围和握力均有改善。分别有1例和2例患者术后出现的轻、中度疼痛症状消失。
使用定制夹具对儿童和青少年桡骨远端骨干骨折畸形愈合进行计算机辅助计划旋转截骨矫形，是一种通过在单一手术中精确矫正同一平面上的旋转和角畸形来简化手术过程的策略。
