摘　　要：目的探讨128层螺旋CT三维重建成像在足部骨折、错位诊疗中的指导价值。方法 51例足部骨折、错位患者,分别行X线片和128层螺旋CT三维重建影像检查,对照术中所见,分析比较两者在诊断和手术治疗中的指导作用。结果 X线片检查10例无法明确诊断,后经手术证实诊断错误1例,128层螺旋CT临床诊断均正确,诊断正确率分别为78.43%和100%。128层螺旋CT与X线片在明确诊断(χ2=35.35,P<0.01)和手术指导方面(χ2=19.49,P<0.01)有显著性差异,128层螺旋CT明显优于X线片。结论 128层螺旋CT能立体、动态地显示足部骨折、错位的形态及程度,有助于明确诊断及手术中指导。Objective To evaluate the diagnosis and treatment evaluation in diseases of bones and joints of foot by 128-slice spiral CT and three-dimensional reconstruction. Methods Fifty-one cases with diseases of bones and joints of foot were undergone X-ray and three-dimensional reconstruction of 128-slice spiral CT. The results were compared with the findings in the operations. Then the function were explored for the diagnosis and therapies, lie- suits There was apparent difference in confirming diagnosis（;t2 35.35, P^0.01 ）and operative guidance（ X2 = 19.49, P^0.01 ）between X-ray and spiral 3-dimensional CT reconstruction, The spiral 3-dimensional CT recon- struction was significantly superior. Conclusion The image of spiral three-dimensional CT reconstruction could show the foot fracture and dislocation directly and stereoscopically, which is of great advantage to clinical diagnosis and treatment.
