摘　　要：背景:足踝部解剖结构较为复杂,有多条伸屈肌腱通过并与多个血管、神经毗邻,在人类完成行走、跳跃及蹲起等活动中发挥重要作用。由于足踝部关节本身为肢体最远端的负重关节,因此通过传统的方法治疗复杂的踝关节周围骨折(如三踝重度粉碎性骨折、Pilon骨折等)或各类重度足踝部畸形(如马蹄内翻足、拇外翻、平足症等)往往很难达到满意的治疗效果。可喜的是,近年来利用3D打印技术显著提升了上述疾病的手术成功率及患者满意度。目的:归纳3D打印技术在足踝外科骨折及畸形类疾病中的治疗现状。方法:利用计算机检索CNKI、PubMed数据库,中文检索词为"3D打印技术,足踝外科,踝关节骨折,足踝部畸形,矫形术",英文检索词为"3D printing,foot and ankle surgery, ankle fracture,foot and ankle deformity,orthopedic surgery",检索时限为2000年1月至2020年2月。共检索到105篇文章,根据纳入与排除标准,最终纳入55篇文献进行综述。结果与结论:①通过在3D实物模型上进行足踝外科手术的术前模拟操作,可提高术者对手术的熟练度,同时可以根据需求,制作个体化手术器械,提高手术成功率;②相较于传统制作的足部矫形器,3D打印技术可以制作出更加符合人体结构的足部矫形器。BACKGROUND:The anatomical structure of the foot and ankle is complex.There are many extensor and flexor tendons passing through the foot and ankle,which is adjacent to many blood vessels and nerves.The foot and ankle play an important role in human walking,jumping and squatting.As the ankle joint itself is the most distal load-bearing joint of the limb,it is difficult to achieve satisfactory therapeutic effect by traditional methods to treat complex periankle fractures(such as severe comminuted trimalleolar fractures and Pilon fractures),or various severe ankle deformities(such as talipes equinovarus,hallux valgus,and flatfoot).Fortunately,in recent years,3D printing technology has significantly improved the success rate and patient satisfaction of the above diseases.OBJECTIVE:To summarize the current situation of 3D printing technology in the treatment of ankle fracture and deformity.METHODS:The computer was used to search CNKI,PubMed database.Chinese search terms were“3D printing technology,ankle surgery,ankle fracture,ankle deformity,orthopedics”.The English search terms were“3D printing,foot and ankle surgery,ankle fracture,foot and ankle deformity,orthopedic surgery”.The retrieval period was from January 2000 to February 2020. A total of 105 articles were retrieved. According to the inclusion and exclusion criteria, 55 articleswere finally included for review.RESULTS AND CONCLUSION: (1) Through the simulation operation of foot and ankle surgery on 3D physical model, the operator’s proficiency in the operationcan be improved. Simultaneously, according to the needs of the operation, individual surgical instruments can be made to improve the success rate of theoperation. (2) Compared with the traditional foot orthosis, 3D printing technology can make foot orthosis more suitable for human body structure.
