| 目的 探讨应用3D打印技术辅助手术治疗复杂胫骨平台骨折的临床效果。方法 选取2014年1月至2017年3月我院收治的复杂胫骨平台骨折病人29例，随机分为观察组（15例）及对照组（14例）进行队列分析比较。观察组胫骨平台经Mimics软件处理，3D打印成1∶1骨折模型，将骨折及健侧模型进行镜像对比，设定手术方案；对照组常规参照术前X线片及CT制定修复方案。术后观察并对两组的手术时间、出血量、术后关节塌陷纠正情况、术后12个月膝关节Rasmussen功能评分进行比较。结果 本研究29例病人的随防时间为（12.55±2.46）个月。观察组的手术时间、出血量明显小于对照组，术后关节塌陷纠正情况优于对照组，差异均有统计学意义（t=2.297，P=0.029；t=2.674，P=0.013；t=2.658，P=0.020）；术后12个月两组膝关节Rasmussen评分差异无统计学意义（P＞0.05）；观察组膝关节功能恢复优良率（93.33%）高于对照组（78.57%）。结论 针对复杂胫骨平台骨折，应用3D打印技术制作骨折模型，通过模拟手术操作可以有效缩短手术时间，减少术中出血，纠正关节面塌陷程度。 |

| Objective To investigate the clinical effect of 3D printing technique in the surgical treatment of complex tibial plateau fractures. Methods Twenty-nine patients with tibial plateau fracture in our hospital from January 2014 to March 2017 were selected, and randomly divided into observation group (15 cases) and control group (14 cases) for cohort study and comparison. The tibial plateau of the observation group was processed by Mimics software, and the fracture model was printed in 3D to 1∶1. The fracture model and the healthy side model were compared, and the surgical plan was set up. The control group routinely drew up the repair plan with preoperative X-ray and CT. The operation time, bleeding volume, correction of joint collapse and Rasmussen functional score of knee joint at 12th month after operation were observed and compared between the two groups. Results The follow-up time was (12.55±2.46) months. The operation time was shorter and bleeding volume was less, and the correction of joint collapse after operation was better in the observation group than in the control group (t=2.297, P=0.029; t=2.674, P=0.013; t=2.658, P=0.020). There was no significant difference in Rasmussen score between the two groups at 12th month after operation (P＞0.05). The excellent and good rate of knee joint function recovery in the observation group (93.33%) was higher than that in the control group (78.57%). Conclusion For complex tibial plateau fractures, using 3D printing technology to establish fracture models and simulate operation can effectively shorten the operation time, reduce intraoperative bleeding, and correct the degree of articular surface collapse. |
