浅析多层螺旋CT三维重建在累及关节面的复杂骨折中的应用

Application of Multi Slice Spiral CT 3D Reconstruction in Complex Fractures Involving the Articular Surface

目的研究分析累及关节面的复杂骨折患者接受多层螺旋CT三维重建诊断的应用效果。方法 2012年3月—2014年3月我院对49例累及关节面复杂骨折患者进行了研究分析,为患者使用多层螺旋CT扫描、X线扫描、常规CT扫描等检查方式,比较三种不同的检查方式的诊断效果。结果 X线检查有3例无移位裂缝骨折、2例塌陷骨折、4例髁间嵴骨折病例被遗漏,无法通过图像来判断骨折的大小、移位、塌陷情况;常规CT有2例髁间嵴骨折病例遗漏;多层螺旋CT没有遗漏,骨折形态和范围清晰,可以多角度观察。结论使用多层螺旋CT三维重建可以直观的对累及关节面的复杂骨折患者的骨折形态直观进行全面的观察,为手术入路提供参考。

Objective To study the application of three-dimensional reconstruction of multi-slice spiral CT in the diagnosis of complex fractures involving the articular surface. Methods From March 2012 to March 2014 in our hospital, 49 cases of complicated fractures involving the articular surface were analyzed for patients with multi-slice spiral CT scanning, X-ray scanning, conventional CT scan, to compare the diagnostic performance of these examinations. Results There were 3 cases with no displacement fracture, and 2 cases of collapse fracture, and the fracture of the intercondylar eminence in 4 cases. Conventional CT had 2 cases of intercondylar eminence fractures missing. Multi slice spiral CT was not missing, the fracture morphology and scope are clear, and can be observed in many angles. Conclusion Multi slice spiral CT three-dimensional reconstruction can visually observe the fracture morphology of patients with complex fractures involving the articular surface.
