摘要:

文题释义:
3D打印技术:作为一座连接虚拟与现实的桥梁,是近年来新兴发展和成熟的一种技术,又叫“快速成型技术”。需要进行3D打印的患者术前行CT扫描及三维重建,将扫描数据导入到Mimics软件,通过一些特殊的材料打印成3D模型。

背景:传统钢板内固定治疗胫骨平台骨折为临床常见标准术式,借助3D打印制作的术前实体模型不但可以有效复位骨折,而且与传统方法相比更加安全、精准及个体化。
目的:探讨3D打印辅助下内固定治疗复杂胫骨平台骨折的临床效果及应用价值。
方法:选择2017年6月至2019年6月在山东第一医科大学附属青岛医院诊断为单侧复杂胫骨平台骨折且需手术治疗的患者40例,根据手术方法不同为3D 组和对照组,每组20例。对照组采取传统手术钢板内固定方法,3D组在术前制作3D打印实体模型,结合模型进行术前手术模拟复位及钢板内固定,指导实际手术操作。术后随访12个月,比较两组患者的手术时间、术中出血量、术中透视次数、术后第3天膝关节Rasmussen放射学评分及术后12个月膝关节功能HSS评分。
结果与结论:①40例患者均顺利完成手术并获得有效随访,随访时间12个月以上,未出现血管神经损伤等并发症,未发生与内固定材料有关的排异反应;②3D组手术时间、术中出血量、术中透视次数均少于对照组(P﹤0.05),术后第3天膝关节Rasmussen放射学评分高于对照组(P﹤0.05);两组术后12个月的膝关节功能HSS评分比较差异无显著性意义(P﹥0.05);③结果表明,3D打印辅助下内固定治疗复杂胫骨平台骨折,在有效复位关节面的基础上可以缩短手术时间、减少术中出血量及透视次数,改善患者膝关节功能。

Abstract: BACKGROUND: Traditional steel plate internal fixation, the common clinical standard procedure, is nothing new in treating fracture of tibia. The preoperative solid model, however, produced by 3D printing technology, works better in resetting the fracture, and is much safe, accurate and individualized, in contrast to classical approach.  
OBJECTIVE: To explore the clinical effect and application value of 3D printing technology in healing complex tibial fractures.
METHODS:  Two groups, 3D group and control group, were divided by 40 cases of unilateral tibial fractures that accepted surgical treatment at Qingdao Hospital of Shandong First Medical University from June 2017 to June 2019. Traditional surgical fixation method was applied to the control group, while the 3D group, however, received operations guided by the preoperative operation of 3D printed solid models, combining the model to perform preoperative simulated reduction and plate internal fixation to guide the actual surgical operation. All patients accepted a 12-month follow-up of comparing the operation time, intraoperative blood loss, intraoperative fluoroscopy times, knee Rasmussen radiology performance on the 3rd day after surgery, and knee HSS score 12 months later.  
RESULTS AND CONCLUSION: (1) All 40 patients were treated ideally and received an effective follow-up visit for more than 12 months. There were no complications such as vascular and nerve injury, and no rejection reactions related to internal fixation materials. (2) Outcomes, such as operation time, intraoperative blood loss, and intraoperative fluoroscopy were less in the 3D group than those in the control group (P < 0.05). Knee Rasmussen radiology performance on the 3rd day after surgery was higher in the 3D group than that of the control group (P < 0.05). There was no significant difference in knee HSS score between the two groups at 12 months (P > 0.05). (3) Results indicate that in terms of complex tibial fractures treatment, 3D printing shines on significantly shortening the operation time, reducing intraoperative blood loss and fluoroscopy times, and enhancing knee function.
