BACKGROUND
This study was aimed to assess the feasibility and efficacy of 3D printing digital template for treatment of cubitus varus deformity.
METHODS
32 patients who underwent lateral closing osteotomy were evaluated between January 2018 and January 2020 in this retrospective study. Navigation templates were used in 17 cases, while conventional surgery in 15 cases. The carrying angles before and after surgery, operation time and elbow joint function were compared.
RESULTS
Navigation templates matched well with the anatomical markers of the lateral humerus. More accurate osteotomy degrees, shorter operation time and less radiation exposure were achieved in the navigation template group ( < 0.05). At the last follow-up time, significant difference was found based on the Bellemore criteria ( = 0.0288).
CONCLUSIONS
The novel navigation template can shorten operation time, improve the lateral closing osteotomy accuracy and improve postoperative elbow joint function.
背景
本研究旨在评估3D打印数字模板治疗肘内翻畸形的可行性和疗效。
方法
在这项回顾性研究中，对2018年1月至2020年1月期间接受外侧闭合截骨术的32例患者进行了评估。17例使用导航模板，15例采用传统手术。比较手术前后的提携角、手术时间和肘关节功能。
结果
导航模板与肱骨外侧的解剖标志匹配良好。导航模板组截骨角度更精确，手术时间更短，辐射暴露更少（<0.05）。在最后随访时，根据贝勒莫尔标准发现有显著差异（=0.0288）。
结论
新型导航模板可缩短手术时间，提高外侧闭合截骨的准确性，并改善术后肘关节功能。
