摘　　要：目的 :探讨 CT三维重建在复杂关节骨折中的指导作用。方法 :收集累及复杂关节的骨折病例 2 7例 ,患者术前均接受 X线、CT平扫和三维重建检查 ,比较三者结果 ,结合术中所见 ,评价螺旋 CT及三维技术在复杂关节骨折中的价值。结果 :依靠螺旋 CT及三维重建技术 ,术前更改诊断 1 1例 ,三维重建逼真地显示了关节的立体表面形态 ,而对显示骨折块之间、关节各部分之间的相互位置关系 ,三维重建明显优于 X线片和 CT平扫。结论 :CT三维重建技术可提高复杂关节骨折的诊疗水平。Objective:To evaluate the useful value of spiral CT and 3 dimensional reconstruction in complicated joint fracture.Methods:Twenty seven patients with complicated joint fracture received preoperative radiography and spiral CT.The results of radiography,CT plain scan and 3 dimensional reconstruction were compared each other according to the operative finding.Results:There were 11 patients whose diagnoses were corrected preoperatively on the basis of the results of spiral CT and 3 dimensional reconstruction.Compared with radiography and CT plain scan,3 dimensional reconstruction clearly exhibited the stereoscopy of injured joint,such as the position of fracture pieces and different parts of the joint.Conclusion:The use of spiral CT and 3 dimensional reconstruction could improve the level of diagnosis and treatment of complicated joint fracture.
