Abstract：
OBJECTIVE: To investigate the clinical efficacy of picture archiving and communication system (PACS) and Photoshop assisted isosceles triangle osteotomy and Kirschner wire fixation with tension band in the treatment of cubitus varus in children.
METHODS: The clinic data of 20 children with cubitus varus treated with isosceles triangle osteotomy of distal humerus and Kirschner wire fixation with tension band from October 2014 to October 2019, were retrospectively analyzed. There were 13 males and 7 females, aged from 3.2 to 13.5 years old, the median age was 6.65 years old. PACS system was applied for the osteotomy design preoperatively, simulating and measuring the side length of isosceles triangle osteotomy. Then, Photoshop system was used to simulate the preoperative and postoperative osteotomy graphics, which could guide precise osteotomy during operation.
RESULTS: All the 20 patients were followed up for 20 to 24 months, with a median of 22.5 months. At the last follow-up, the carrying angle of the affected limb was 5 ° to 13 °, with a median of 8.3 °. The clinical efficacy was evaluated according to the Flynn elbow function score:excellent in 16 cases, good in 2 cases, and fair in 2 cases.
CONCLUSIONS: The treatment of cubitus varus in children by isosceles triangle osteotomy and Kirschner wire fixation with tension band assisted by PACS and Photoshop system has shown good clinical outcome.

摘要：
目的：探讨图片存档与通信系统（PACS）和Photoshop辅助等腰三角形截骨术及克氏针张力带固定治疗儿童肘内翻的临床疗效。
方法：回顾性分析2014年10月至2019年10月采用肱骨远端等腰三角截骨加张力带克氏针固定治疗20例肘内翻患儿的临床资料。有13名男性和7名女性，年龄在3.2至13.5岁之间，中位年龄为6.65岁.术前采用PACS系统进行截骨设计,模拟并测量等腰三角形截骨的边长。然后，采用Photoshop系统模拟术前、术后截骨图形,可以在手术中指导精确的截骨。
结果：20例患者均获随访，随访时间20~24个月。中位数为22.5个月。在最后一次随访中，患肢的携带角度为5°至13°，中位数为8.3°。根据Flynn肘关节功能评分评价临床疗效：优16例，在两种情况下都很好，在两种情况下公平。
结论：在PACS和Photoshop系统的辅助下，采用等腰三角形截骨术和张力带克氏针固定治疗儿童肘内翻已显示出良好的临床效果。
