摘　　要：目的：探讨三维ＣＴ重建在评估胸腰椎骨折中的临床应用价值。方法：对１４例胸腰椎骨折患者行Ｘ线片、ＣＴ扫描和三维ＣＴ重建检查，评估胸腰椎骨折脱位的程度，拟定治疗方案。结果：１４例胸腰椎骨折Ｘ线片、ＣＴ扫描和三维ＣＴ重建诊断的创伤量分别为２９、４９和５０。其中１３例采取手术治疗。结论：三维ＣＴ重建能多角度立体显示椎体及附件的骨折，显示小关节水平方向的移位；能立体定位椎管内的碎骨块，显示继发性椎管狭窄的程度，指导术者对胸腰椎骨折准确分型，术中良好复位，解除骨块对脊髓的压迫。Objective:To study the clinical significance of three dimensional computed tomography (3 D CT) in thoracolumbar fractures.Method:14 cases of thoracolumbar fractures took the preoperative examination of X ray,CT scan and 3 D CT.Based on these images,appopriate treatment were selected.Result:Analyzing 3 D CT images of 14 cases of thoracolumbar fractures,the traumatic quantity was 50,while in X ray plains and axial CT was 29 and 49.13 cases had got surgical treatment.Conclusion:Through different views of spine,3 D CT can show the fractures of vertebral body and appendix clearly.And it is superior to CT scan in demonstrating the horizontal displacement of articular processes. It can help us locating the fragments in the vertebral canal spatially and evaluating the secondary narrowness of vertebral canal.So that the operator can evaluate fractures correctly,selecte the appropriate surgical approach.Remove the fragments in vertebral canal successfully and perform ideal reduction and fixation.
