螺旋CT三维成像对骨盆及髋臼骨折临床治疗的指导意义

Effect of Three-dimensional Computed Tomographin Pelvis and Acetabulum Fractures

目的 探讨用三维CT重建评价骨盆骨折及髋臼骨折的临床应用价值。方法 对 2 4例骨盆骨折及髋臼骨折患者的X线片、三维CT重建进行对比分析 ,对骨折进行分型 ,选择合适的治疗方案。结果 通过X线平片确诊 2 1例 ,漏诊 3例 (12 5 % )。三维CT重建使 2 4例均明确诊断 ,确诊率 10 0 %。并明确评价骨折形态和骨折移位方向。 2 1例均接受了手术治疗。结论 三维CT重建能多方位 ,立体显示骨盆及髋臼骨折的形态。帮助术者正确估计骨折类型及移位程度 ,选择合适的手术入径 ,准确复位 ,合理固定 。

Objectives To study the clinical significance of three dimensional computed tomograph reconatruction (3-D CT)in effect of pelvis and acetabulun fractures.Methods 24 cases of pelvis and acetabulum fractures were examined preoperatively under X-ray and 3-D CT.Based on the images,the fractures were comparative analyzed,classified and appropriately treated.Results 21 cases were made definite diagnosis by X-ray.All patients were made definite diagnosis by 3-D CT.The pattern displacement orientation and extent of fracture fragments were examined.According to 3-D CT images,21 cases underwent opration.Conclusions Through diferent views of pelvis and acetabulum,3-D CT helps to evaluate the pattern and degree of fractures,it plays an important role than X-ray and CT scan.It can supply the best choice of surgical approach and achieve good reduction and internal fixation.
