CT三维重建技术在复杂骨盆及髋臼骨折中的应用

Application of three-dimensional CT in complicated pelvis and acetabulum fractures

目的 :探讨CT三维重建技术在常见复杂骨折诊断中的临床应用价值。方法 :对 3 0例复杂骨盆及髋臼骨折患者进行CT三维重建分析 ,并常规X线片及CT二维成像观察病变的立体形态及其与周围结构的关系 ,其中 2 5例行手术 ,比较以上 3种方法的检查及术中情况。结果 :3种方法间诊断率有显著性差异 (P <0 0 0 1) ,二维CT与三维重建间无显著性差异 (P >0 0 5 )。结论 :CT三维重建清晰立体 ,可以根据需要从不同的方位显示损伤情况 ,指导临床诊断及手术意义重大。

Objective:To evaluate the clinical value of CT three-dimensional reconstruction in complicated pelvis and acetabulum fractures.Methods:Thirty cases of complicated fractures of pelvis and acetabulum were investigated by X-ray CT scan and CT three-dimensional reconstruction,25 of them underwent operative treatment.In order to show the relative merits of above 3 examinations,the results and intraoperative views were compared.Results:The positive rate of CT scan and CT three-dimensional reconstruction were relatively higher than X-ray ( P<0.01 ),there were no significant difference between CT scan and CT three-dimensional reconstruction ( P>0.05 ).Conclusion:With clear stereo,CT three-dimensional reconstruction can show the injury in different directions,which is of clinical significance in diagnosis and operation.
