摘要:

背景:CT重建骨折三维模型不能进行虚拟复位、内固定,不能制定合理的修复方案,无法完全满足临床骨科医师的需要。
目的:应用医用软件Mimics、Solidworks在胫骨近端骨折中三维重建、复位并设计内固定方案,指导临床修复手术,并观察其修复效果。
方法:纳入40例胫骨近端骨折患者,进行高速CT薄层扫描,在Mimics中对骨折进行重建、复位,以Solidworks进行内固定钢板、螺钉的选择和设计,并在骨折复位三维模型上进行虚拟内固定。临床据此方案进行骨折修复手术,术后观察患者的骨折愈合及自我评价情况(MacNab标准)。
结果与结论:所有骨折均进行了三维重建、复位,以准确的内固定钢板及螺钉进行了虚拟内固定。临床骨折修复过程顺利,按术前设计的数字化方案成功完成,效果满意。40 例患者获随访12-24 个月,骨折愈合时间12-18周,平均13.6周;完全负重时间15-17周,平均15.8周。患者自我评价依据MacNab标准:优29例,良9例,可2例,差0例,优良率95%。术中钢板和螺钉规格、进钉长度、直径、位置、角度等与术前高度一致。提示应用Mimics及Solidworks可在个人电脑上设计出胫骨近端骨折内固定的数字化方案,可以为现实手术提供良好参考。

Abstract:

BACKGROUND: On CT reconstruction of three-dimensional model, fracture virtual reduction and internal fixation cannot be achieved, so reasonable operation scheme cannot be formulated. It cannot fully meet the needs of clinical orthopedics physicians.
OBJECTIVE: To explore the methods to perform three-dimensional reconstruction, reduction on proximal tibial fracture and designing digital internal fixation using Mimics and Solidworks software, and to guide the operation and to observe the clinical efficacy.
METHODS: A total of 40 cases of proximal tibial fracture patients were enrolled and treated with high-speed CT scan. Three-dimensional reconstruction and reduction were performed in Mimics. The plates and screws were designed and selected in Solidworks. Virtual internal fixation on the reduced three-dimensional models was performed. This operation scheme was prepared and applied. Union of fracture and self-evaluation (MacNab standard) were observed after surgery.
RESULTS AND CONCLUSION: Three-dimensional reconstruction, reduction and accurate fixation of plates and screws were conducted in all bone fracture models. The clinical operation was smoothly going, completed successfully according to the digital scheme of the preoperative design. The curative effect is satisfied. A total of 40 patients were followed up for 12-24 months. The time of fracture union was 12-18 weeks, averagely 13.6 weeks. The time of complete weight loading was 15-17 weeks, averagely 15.8 weeks. In accordance with MacNab standard, there were excellent in 29 cases, good in 9 cases, average in 2 cases, poor in 0 case, with the excellent and good rate of 95%. Plate and screw specifications, screw length, diameter, position, and angle were consistent with preoperative data. These findings show that the digital scheme of internal fixation for proximal tibial fracture could be designed in Mimics and Solidworks with a personal computer. Our experience can provide a good reference for the practical operation
