3D打印技术在严重骨盆髋臼骨折内固定手术中的应用

通过采集严重骨盆髋臼骨折患者的薄层CT扫描数据, 在Mimics中进行图像编辑、三维重建及分析总结, 探讨3D打印技术在严重骨盆髋臼骨折内固定手术中的应用. 结果表明, 3D打印技术有利于术前进行手术设计、术前预弯钢板, 有利于判断畸形及术中在确定截骨部位、复位的关键标记以及判断复位质量. 3D打印技术具有快速性、高仿真性、高成功率及通用性意义, 具有推广价值.

Application of internal fixation for severe pelvic acetabular fracture with 3D printing technique

The application of 3D printing in internal fixation of severe pelvic acetabular fracture was investigated in the current study. Thin-layer CT scan data of patients with severe pelvic acetabular fractures were collected and analyzed by image editing and three-dimensional reconstruction in Mimics. 3D printing is helpful for preoperative surgical design, prebending of plate prior to operation, and judge of deformity. The site of the osteotomy, the key marker of reset and the judge of reset quality could thus be determined intraoperatively. 3D printing has the advantages of rapidity, high simulation, high success rate and universality.
