摘要

目的探讨基于3D打印技术的数字化支具固定联合微创截骨手法整复术治疗母外翻（HAV）的效果。方法选取于2023年6月~2024年11月广州中医药大学第三附属医院收治的HAV患者作为研究对象，回顾性依据固定方法的不同按照1：1比例纳入A组和B组各39例，共78例。A组给予常规固定，B组给予基于3D打印技术的数字化支具固定。两组术后均随访6个月。比较两组治疗优良率、疼痛、足踝功能及影像学指标及并发症。结果术后3、6个月，B组视觉模拟量表（VAS）评分更低（P<0.05）。术后6个月，B组足踝功能评分更高，外翻角（HVA）、第1、2跖骨间角（IMA）、跖骨远端关节角（DMAA）更低，第一跖骨长度更长（P<0.05）。结论基于3D打印技术的数字化支具固定对HAV患者微创截骨手法整复术的治疗效果无明显影响，可能可减轻疼痛、改善影像学指标、提高足踝功能，安全性良好。

Abstract

Objective To explore the effect of digital support fixation combined with minimally invasive osteotomy technique based on 3D printing technology for the treatment of hallux valgus (HAV). Methods HAV patients admitted to the Third Affiliated Hospital of Guangzhou University of Chinese Medicine from June 2023 to November 2024 were selected as the research subjects. A retrospective analysis was conducted, and patients were divided into the group A and the group B in a 1:1 ratio based on different fixed methods, with 39 cases in each group, for a total of 78 cases. The patients of group A received conventional fixation, while the patients of group B received brace fixation based on 3D printing technology. Both groups of patients were followed up for 6 months after surgery. The excellent and good rate, pain levels, ankle function and radiographic indicators, as well as complications of two groups were compared. Results At 3 and 6 months after surgery, the visual analog scale (VAS) scores of the patients in group B were lower (P<0.05). At 6 months after surgery, the ankle function scores in the patients in group B was higher; The hallux valgus angle (HVA), first and second metatarsal angles (IMA), and distal metatarsal articular angle (DMAA) were lower. The length of the first metatarsal bone was longer (P<0.05). Conclusions The use of 3D printing technology-based braces for fixation had no significant impact on the therapeutic effect of minimally invasive osteotomy technique and manual reduction for patients with HAV. However, it might help to alleviate pain, improve imaging indicators, enhance ankle function, and have good safety and good safety.
