摘　　要：目的:探讨CT三维重建技术诊断闭合性胫骨骨折合并踝关节损伤的准确性。方法:对117例在复旦大学附属中山医院就诊的闭合性胫骨骨折患者术前常规行X线及三维CT检查。比较两种检查手段对胫骨骨折合并踝关节损伤的诊断价值。结果:术前X线检查发现19例胫骨骨折患者合并后踝骨折;而三维CT重建图像发现34例患者伴后踝骨折,比X线摄片多检查出15例。结论:对于胫骨骨折合并后踝关节损伤,三维CT重建技术较X线检查的诊断率更高,能降低漏诊率。Objective：To explore the accuracy of CT three dimensional reconstruction technique for the diagnosis of tibia shaft fracture accompanied by ankle injury.Methods：Both X-ray examination and three dimensional CT scanning were conducted for the 117 patients with closed tibia shaft fracture,who went to Zhongshan Hospital of Fudan University,before surgery.The numbers of patients,who were diagnosed with tibia shaft fracture accompanied by ankle injury,were compared between the two examination methods.Results： Nineteen patients with tibia shaft fracture were diagnosed with accompanied posterior malleolar fracture by X-ray examination before surgery.However,34 patients were diagnosed with accompanied posterior malleolar fracture by CT three dimensional reconstruction images.Thus,15 more patients were diagnosed by CT three dimensional reconstruction technique than that by X-ray imaging.Conclusions：Comparing with X-ray examination,three dimensional CT reconstruction technique could increase the diagnosis accuracy for posterior malleolar fracture associated with tibia shaft fracture and reduce the rate of missed diagnosis.
