摘要

目的研究3D打印技术联合计算机辅助下Taylor空间外固定架治疗下肢复杂畸形的临床效果。方法回顾性分析2016 年1月至2020年1月在青海大学附属医院治疗的13例下肢畸形患者，其中男性5例，女性8例，年龄18~41岁，平均(31.62±8.99)岁。13例患者中足畸形患者12例(3例双足)和小腿畸形患者1例，患者通过3D打印技术重建畸形模型，辅助Taylor空间外固定架进行矫形手术治疗，术后评价主要根据Paley标准，足畸形患者采用美国足踝外科协会(American orthopedic foot ankle society，AOFAS)踝-后足评分系统及曼彻斯特-牛津足部问卷(Manchester-Oxford Foot Questionnaire，MOXFQ)评分量表进行术前和术后的评价。结果术后患者随访时间46~132周，平均(79.76±32.68)周。拆除外架后患肢进行Paley评价，优6例次，良7例次，一般3例次，手术前后AOFAS及MOXFQ评分比较，差异有统计学意义(P＜0.05)。结论 3D打印技术联合计算机辅助下Taylor空间外固定架治疗下肢复杂畸形具有数据精准、可控性强的特点，具有良好的临床效果。

Abstract：Objective To study the clinical effect of 3D printing technology combined with computer-assisted Taylor space external fixator in the treatment of complex deformities of lower limbs.Methods A retrospective analysis was conducted on 13 patients with lower extremity deformities treated in the Affiliated Hospital of Qinghai University from January 2016 to January 2020，including 5 males and 8 females，with an average age of (31.62±8.99)years.And 12 patients with foot deformities (15 feet) and 1 patient with tibial deformity.The patients were received orthopedic surgeries of 3D printing technology and Taylor space external fixator.Postoperative evaluation according to the standards of Paley.Patients with foot deformities before and after surgery were evaluated using the American Society of Foot and Ankle Surgery (AOFAS) Ankle-Hindfoot Score System and Manchester-Oxford Foot Questionnaire (MOXFQ) score scale.Results The postoperative follow-up time was (79.76±32.68)weeks.After the external frame removed，Paley evaluation of the limb showed that 6 cases were excellent，7 cases were good and 3 cases were general.AOFAS and MOXFQ scores showed significant differences in preoperative and postoperative patient scores (P＜0.05).Conclusion The combination of 3D printing technology and computer-assisted Taylor space external fixation has the characteristics of accurate data and strong controllability and it has good clinical effects in the treatment of complex deformities of the lower limbs.
