四肢骨关节隐匿骨折的CT检查

Application of CT Diagnosis in Extremital Bone and Joint Occult Fracture

目的:探讨CT对四肢骨关节隐匿性骨折的诊断价值。方法:36例急性四肢外伤患者均行X线摄片检查,对X线摄片有怀疑、临床体征明显或随访仍有怀疑、或软组织肿胀明显的病例做CT检查,共检出骨关节隐隐性骨折29例。结果:所选病例外伤X线平片均未显示明显骨折线,隐匿性骨折阳性率达80.6%(29/36)。CT检均清楚显示骨折线。结论:四肢骨创伤性病变影像诊断中,CT对X线平片不易发现或临床体征、症状不能除外的骨关节隐匿骨折,是有效的检查手段。

Objective： To investigate the value of CT in detecting extremitat bone and joint obscure fractures. Methods： Thirty-six cases with acute extremital bone and joint trauma were examined using radiography, CT when plain films failed to reveal suspected fractures, suggestive clinic symptoms or follow up, or soft tissues in evident swelled,29 cases were found obscure fractures. Results： All 36cases had normal radiographic results, the detective rates were 80.6%（29/36）.29 cases were studied using CT, fraetural lines were found without exception. Conclusion： In the image diagnosis of extremital bone and joint trauma, CT is the effective way of diagnosing means when plain films fail to reveal fractures in the setting of suggestive symptoms and positive physical examination.
