3D打印技术在复杂胫骨平台骨折内固定术中的应用

Application of three-dimensional printing technology in internal fixation for complex tibial plateau fracture

目的探讨3D打印技术应用于复杂胫骨平台骨折内固定术中的治疗效果。方法选取2017年3月至2019年3月南阳市第二人民医院收治的110例复杂胫骨平台骨折患者为研究对象,按照电脑双盲法分为对照组(n=55)和观察组(n=55)。对照组接受传统切开复位内固定术,观察组开展3D打印技术辅助内固定术。比较两组患者的手术相关情况、骨折愈合及关节功能恢复情况。结果观察组手术时间、骨性愈合时间[(91.52±10.28)min,(3.15±0.51)ml]均短于对照组[(150.23±30.25)min,(4.12±0.72)ml],观察组术中出血量[(531.25±250.12)ml]少于对照组[(770.32±305.45)ml],差异有统计学意义(P<0.05)。观察组骨折愈合情况及膝关节功能恢复效果均优于对照组,差异有统计学意义(P<0.05)。结论在复杂胫骨平台骨折患者内固定术中利用3D打印技术辅助治疗,可有效缩短手术时间、减少术中出血,促进骨愈合及膝关节功能恢复,利于提升整体手术效果。

Objective To analyze the effects of three-dimensional(3D)printing technology in internal fixation for complex tibial plateau fracture.Methods A total of 110 patients with complex tibial plateau fracture who were treated in the Nanyang Second General Hospital from March 2017 to March 2019 were divided into control group(n=55)and observation group(n=55)by computer double blind method.Control group underwent open reduction and internal fixation,and observation group was given 3D printing technology assisted internal fixation.The surgical situations,fracture healing and recovery of joint function were compared between the two groups.Results The operation time and bone healing time in observation group were(91.52±10.28)min,(3.15±0.51)ml,respectively,shorter than(150.23±30.25)min and(4.12±0.72)ml in control group,and the intraoperative bleeding volume of observation group was(531.25±250.12)ml,less than(770.32±305.45)ml of control group(P<0.05).The fracture healing time and recovery of knee joint function in observation group were better than those in control group(P<0.05).Conclusions 3D printing technology assisted internal fixation in the treatment of complex tibial plateau fracture can shorten operation time,reduce intraoperative bleeding volume,promote bone healing and recovery of knee joint function,and improve surgical effects.
