To evaluate the effect of 3D printing in treating trimalleolar fractures and its roles in physician-patient communication, thirty patients with trimalleolar fractures were randomly divided into the 3D printing assisted-design operation group (Group A) and the no-3D printing assisted-design group (Group B). In Group A, 3D printing was used by the surgeons to produce a prototype of the actual fracture to guide the surgical treatment. All patients underwent open reduction and internal fixation. A questionnaire was designed for doctors and patients to verify the verisimilitude and effectiveness of the 3D-printed prototype. Meanwhile, the operation time and the intraoperative blood loss were compared between the two groups. The fracture prototypes were accurately printed, and the average overall score of the verisimilitude and effectiveness of the 3D-printed prototypes was relatively high. Both the operation time and the intraoperative blood loss in Group A were less than those in Group B (P < 0.05). Patient satisfaction using the 3D-printed prototype and the communication score were 9.3 ± 0.6 points. A 3D-printed prototype can faithfully reflect the anatomy of the fracture site; it can effectively help the doctors plan the operation and represent an effective tool for physician-patient communication.
为评估3D打印在治疗三踝骨折中的效果及其在医患沟通中的作用，将30例三踝骨折患者随机分为3D打印辅助设计手术组（A组）和非3D打印辅助设计组（B组）。A组中，外科医生使用3D打印制作实际骨折的模型以指导手术治疗。所有患者均接受切开复位内固定术。设计了一份针对医生和患者的问卷，以验证3D打印模型的逼真度和有效性。同时，比较两组的手术时间和术中出血量。骨折模型打印准确，3D打印模型逼真度和有效性的平均总分较高。A组的手术时间和术中出血量均少于B组（P<0.05）。使用3D打印模型的患者满意度和沟通得分为9.3±0.6分。3D打印模型能如实反映骨折部位的解剖结构；能有效帮助医生规划手术，是医患沟通的有效工具。
