Our study described a computer-assisted, three-dimensional (3-D), planned surgical technique of a radial shortening osteotomy. The osteotomy of the distal radius was planned with computer assistance on 3-D bone models based on computed tomography data. The objective was to maximize the contact zone of the sigmoid notch with the ulnar head. Between 2012 and 2020 we treated 14 wrists in 11 patients with symptomatic ulnar-minus variance with a mean follow-up of 44 months (range 8 to 98) and a mean age of 28 years (range 19 to 38). Postoperatively, patients showed a decrease in pain at rest and during effort (numeric rating scale from 4.4 to 0 and 7.5 to 4.5, respectively). The range of motion postoperatively was similar to the contralateral side. Grip strength increased from 24 kg to 30 kg. The Disability of the Arm, Shoulder, and Hand and the Patient-Rated Wrist Evaluation scores were 28 and 35 postoperatively, respectively. Our technique of 3-D computer-assisted distal radioulnar joint reconstruction led to a pain reduction and improvement of the hand function in patients with symptomatic ulnar-minus variance. IV.
我们描述了一种计算机辅助的三维（3-D）桡骨缩短截骨术的手术计划技术。根据计算机断层扫描数据，在 3-D 骨模型上进行计算机辅助的远端桡骨截骨术计划。目的是使乙状切迹与头状骨的接触区域最大化。2012 年至 2020 年，我们治疗了 11 名患者的 14 个腕关节，这些患者均有症状性尺骨负变异，平均随访 44 个月（8 至 98 个月），平均年龄 28 岁（19 至 38 岁）。术后，患者的静息和活动时疼痛均有所减轻（数字评分从 4.4 降至 0 和从 7.5 降至 4.5）。术后的活动范围与对侧相似。握力从 24 公斤增加到 30 公斤。术后患者的手臂、肩部和手的残疾程度和患者自评手腕评估评分分别为 28 和 35。我们的 3-D 计算机辅助桡尺远侧关节重建技术可减轻尺骨负变异患者的疼痛并改善手部功能。IV.
