Abstract：
UNASSIGNED: Various osteotomy methods have been proposed in the treatment of cubitus varus. We designed an improved stepped osteotomy to achieve improved deformity correction. We refer to this new approach as double-closed wedge broken-line osteotomy and report a series of clinical and imaging results (deformity correction, range of motion [ROM], function, osteotomy healing, and complications) of patients with cubitus varus treated with this technique.Between July 2014 and July 2019, we treated 9 cases of cubitus varus using the new technique. The study was conducted in accordance with the principles of the Declaration of Helsinki, and the study protocol was approved by the ethics committee of Shenzhen Children\'s Hospital. We obtained written parental consent for the minors before the study was begun. We compared preoperative and postoperative clinical and imaging parameters (humeral elbow-wrist angle, elbow ROM) in all patients. Postoperative evaluation was performed by telephone interview and outpatient review. The median follow-up was 23.2 months (range, 3-63 months).The median humeral elbow-wrist angle modified from -14.27 to 15.15. The median clinical and imaging parameters after correction of deformity were not different from that of the normal side. Using our rehabilitation program, all patients recovered preoperative elbow ROM at the last follow-up.Our double-closed wedge broken-line osteotomy has a larger cancellous bone contact surface. The deformity correction is satisfactory, the osteotomy healing is reliable, and the incidence of complications is low.Level of Evidence: Level IV.
摘要：
UASSIGNED：已经提出了各种截骨方法来治疗肘内翻。我们设计了一种改进的阶梯式截骨术，以实现改良的畸形矫正。我们将这种新方法称为双闭合楔形断线截骨术，并报告了一系列临床和影像学结果（畸形矫正，运动范围[ROM]，函数,截骨愈合，和并发症）用这种技术治疗的肘内翻患者。2014年7月至2019年7月，我们使用新技术治疗了9例肘内翻。这项研究是根据《赫尔辛基宣言》的原则进行的，研究方案获得深圳市儿童医院伦理委员会批准。在研究开始之前，我们获得了未成年人的父母书面同意。我们比较了术前和术后的临床和影像学参数（肱骨肘-腕部角度，所有患者的肘部ROM）。术后评估通过电话访谈和门诊复查进行。中位随访时间为23.2个月(范围,3-63个月）。肱骨肘部-腕部正中角度从-14.27修改为15.15。畸形矫正后的中位临床和影像学参数与正常侧无差异。利用我们的康复计划，所有患者在末次随访时恢复术前肘关节ROM.我们的双闭合楔形断线截骨术具有较大的松质骨接触面。畸形矫正令人满意，截骨愈合是可靠的，并发症发生率低。证据级别：IV级。
