3DX线透视影像导航治疗关节内和近关节骨折——早期经验报告

Navigation on 3D fluoro-images for articular and juxta-articular fractures -A report of the early experience

目的利用术中获得的3D透视影像导航关节内和近关节骨折的复位与固定。方法根据标准X线片和3DCT扫描重建图像,进行术前骨折分析。用Stryker导航系统导航胫骨平台骨折、胫骨远端关节内和近关节骨折的复位和固定。结果共治疗了11例胫骨平台骨折、5例Pilon骨折和1例股骨髁部骨折。所有骨折均可经小切口中空螺钉固定主要骨折块。结论联合应用术中3D透视影像和CT的导航系统有助于减少微创技术固定关节内骨折时的X线暴露,其准确性可接受。

Objective To use 3D fluoro-images for reduction and fixation of articular and juxta-articular fractures. Methods Presurgical analysis was carried out based on standard plan X-rays and 3D fluoro-images. Stryker 3D Fluoro-navigation system was used for reduction and fixation of articular and juxta-articular fractures at the tibial plateau and distal tibia. Results A total of 11 tibial plateau fractures, 5 Pilon fractures and 1 femoral condyle fracture were treated. All the main fracture frangments were fixed via a small incision with canulated screws. Conclusion Navigation surgery based on the combined use of 3D fluoro-and CT-images is helpful in reducing the X-ray exposure in a minimally invasive surgery for articular fractures with acceptable accuracy.
