[摘要] 目的 探討个性化3D打印对小儿肱骨髁上骨折进行外固定治疗的效果，为临床提供参考。 方法 选择2019年3月至2020年3月江西省新余市中医院骨科接受治疗的60例患为研究对象，随机分为两组，观察组采用单纯中医手法复位联合个性化3D打印的支具固定骨折断端治疗，对照组采用单纯中医手法复位联合小夹板固定治疗，分别观察两组患者的治愈率、并发症发生率，进行比较。 结果 观察组患儿治疗总有效率为96.67%，显著高于对照组73.33%，差异有统计学意义（χ2=6.065，P<0.05）;观察组患儿并发症发生率为6.67%，显著低于对照组的26.67%，差异有统计学意义（χ2=6.309，P<0.05）。 结论 单纯中医手法复位联合个性化3D打印的支具固定骨折断端治疗肱骨髁上骨折患儿疗效显著，可显著改善患者临床症状，同时显著降低并发症的发生，值得临床推广。

[Abstract] Objective To explore the effect of personalized 3D printing on external fixation of supracondylar fracture of humerus in children， and to provide a reference for clinical practice. Methods Sixty patients who were treated in the Department of Orthopedics of Xinyu Hospital of Traditional Chinese Medicine in Jiangxi Province from March 2019 to March 2020 were selected as the research objects. 60 patients were randomly divided into the observation group（n=30） and the control group（n=30）. The observation group was treated with manual reduction of traditional Chinese medicine combined with personalized 3D printed brace to fix the broken end of fracture，while the control group was treated with traditional Chinese medicine manual reduction combined with small splints for fixation. The cure rate and complication rate of the two groups were observed and compared. Results The total effective rate in the observation group was 96.67%， which was significantly higher than that in the control group（73.33%）， and the difference was statistically significant（χ2=6.065， P<0.05）. The incidence of complications in the observation group was 6.67%， which was significantly lower than that in the control group（26.67%）（χ2=6.309， P<0.05）. Conclusion Manual reduction of traditional Chinese medicine combined with personalized 3D printed brace for fixation of broken ends is effective in treating patients with supracondylar fracture of humerus， which can significantly improve patients′ clinical symptoms and significantly reduce the occurrence of complications.Thus it is worthy of clinical promotion.

在小儿骨折中，肘部的骨折，最常见的是肱骨髁上骨折，通常骨折的部位为肱骨远端，每10个肘部骨折的儿童患者，就有5～6个肱骨髁上骨折，以5～12岁的儿童最为多见[1]。若对此疾病处理不及时，不正确，则患者易出现肘内翻畸形、神经损伤以及缺血性肌肉痉挛等疾病，给患儿的生活质量带来不利影响，严重影响患儿家庭的日常生活[2]。所以，给患儿寻找一种更加有效，更加安全的外固定手段是非常有必要的。随着科学技术的发展，3D打印技术在骨科得到了越来越完善的应用，其效果也令人满意。本次研究目的是分析中医手法复位联合个性化3D打印的支具固定骨折断端对儿童肱骨髁上骨折外固定的效果，将选取在2019年3月至2020年3月之间60例骨科的病例进行观察，现报道如下。
