目的:对16例腕关节外伤患者的X线平片、CT及三维CT3种检查进行对比研究,评估在临床诊断中的价值.材料与方法:16例中,男8例,女8例,平均年龄41岁.全部病例均经X线平片、常规CT和三维CT成像,X线平片包括常规位置和特殊位置.CT机为SOMATOMCRF.结果:16例中X线平片阳性15例18处,阴性1例.CT及三维CT全部阳性,共发现骨折及脱位32处.其中腕部复杂性骨折合并脱位10例,多发性骨折不合并脱位2例,单纯性骨折4例.16例中10例开放复位手术证实,4例手法复位,2例单纯石膏托固定治愈证实.结论:在腕关节外伤X线检查中,平片占有重要地位,CT优于平片,三维CT是平片和CT不可代替的补充“,”Objective: To evaluate plainfilm, CT and 3D CT in the diagnosing of wrist trauma by a comparison study in 16 cases.Materials and Methods:Plainfilm, routine CT and 3D CT were performed in 16 cases. The findings on different images were analyzed and compared.Results:All cases showed positive findings on CT and 3D CT, and the same was true for plainfilm except one case which showed no fracture sign. Fractures and dislocations were found in 32 sites altogether, including complicated wrist fractures with dislocation (n=10), multiple fractures without dislocation (n=2) and simple fractures (n=4). Of 16 cases, 10 were confirmed by open reduction, 4 by manual reduction and 2 by plaster support cure.Conclusion: This study indicates that the plainfilm plays an important role in the examination of wrist trauma, though CT is superior to it, while 3D CT is a helpful supplement to them.
