Abstract

OBJECTIVE

Tibial plateau fractures are common intra-articular fractures that pose classification and treatment challenges for orthopedic surgeons.

OBJECTIVE

This study examines the value of 3D printing for classifying and planning surgery for complex tibial plateau fractures.

METHODS

We reviewed 54 complex tibial plateau fractures treated at our hospital from January 2017 to January 2019. Patients underwent preoperative spiral CT scans, with DICOM data processed using Mimics software. 3D printing technology created accurate 1:1 scale models of the fractures. These models helped subdivide the fractures into seven types based on the tibial plateau's geometric planes. Surgical approaches and simulated operations, including fracture reduction and plate placement, were planned using these models.

RESULTS

The 3D models accurately depicted the direction and extent of fracture displacement and plateau collapse. They facilitated the preoperative planning, allowing for precise reconstruction strategies and matching intraoperative details with the pre-printed models. Post-surgery, the anatomical structure of the tibial plateau was significantly improved in all 54 cases.

CONCLUSION

3D printing effectively aids in the classification and preoperative planning of complex tibial plateau fractures, enhancing surgical outcomes and anatomical restoration.

摘要

目的

胫骨平台骨折是常见的关节内骨折，给骨科医生带来了分类和治疗方面的挑战。

目的

本研究探讨3D打印在复杂胫骨平台骨折分类及手术规划中的价值。

方法

回顾性分析我院2017年1月至2019年1月收治的54例复杂胫骨平台骨折患者。患者术前行螺旋CT扫描，利用Mimics软件处理DICOM数据。通过3D打印技术制作出精确的1:1比例骨折模型。这些模型有助于根据胫骨平台的几何平面将骨折细分为七种类型。利用这些模型规划手术入路及模拟手术，包括骨折复位和钢板置入。

结果

3D模型准确描绘了骨折移位方向及平台塌陷程度。它们有助于术前规划，能制定精确的重建策略，并使术中细节与预打印模型相匹配。术后，54例患者胫骨平台的解剖结构均有明显改善。

结论

3D打印能有效辅助复杂胫骨平台骨折的分类及术前规划，提高手术效果及解剖复位程度。
