目的探讨CT与X线平片检查在髋臼骨折诊断中的临床应用价值。方法对照分析18例髋臼骨折CT、X线平片及临床治疗随访资料。结果18例髋臼骨折中前壁骨折4例,前柱骨折4例,后壁骨折2例,后柱骨折2例,复杂骨折6例。伴有盆腔内软组织肿胀11例。其中X线平片误漏诊4例。CT检出骨碎片27块,X线平片检出12块,其中关节腔内游离骨碎片CT检出17块,X线平片检出4块。股骨头脱位7例,伴股骨头骨折3例,其中X线平片漏诊1例。结论CT显示关节腔内碎骨片,确定骨折分型及了解盆腔软组织受损情况优于X线平片检查。
Objective To investigate the clinical value of CT and X-ray plain film in the diagnosis of acetabular fractures. Methods 18 cases of acetabulum fracture CT, X-ray and clinical follow-up data were analyzed. Results In the 18 cases of acetabular fractures, anterior wall fracture in 4 cases, anterior column fracture in 4 cases, posterior wall fracture in 2 cases, posterior column fracture in 2 cases and complex fracture in 6 cases. Accompanied by pelvic soft tissue swelling in 11 cases. One X-ray film misdiagnosis in 4 cases. Twenty-seven bone fragments were detected by CT and 12 were detected by X-ray. Among them, 17 were detected by CT in the joint cavity and 4 by X-ray. Femoral head dislocation in 7 cases, with femoral head fracture in 3 cases, of which 1 case of missed diagnosis of X-ray. Conclusion CT showed broken pieces in the articular cavity to determine the fracture type and to understand the pelvic soft tissue damage better than the X-ray examination.
