CT在髋关节脱位中的诊断价值

目的探讨CT在髋关节脱位中的诊断价值.方法分析并比较17例经X线平片及CT检查的髋关节脱位病例.结果X线平片显示髋关节脱位15例、骨折10例、软组织肿胀9例、复位后关节间隙增宽6例及关节内碎骨片3例.CT显示脱位及骨折17例、软组织肿胀15例、复位后关节间隙增宽11例及关节内碎骨片10例.结论CT对显示髋关节脱位的方向和程度、髋臼骨折、复位前后关节内骨碎片及软组织改变均有明显优势,我们认为可以将CT检查作为髋关节脱位,尤其是复位后的一种常规检查.

Diagnostic Value of CT in the Hip Joint Dislocation

Objective To discuss the diagnostic value of CT in the hip joint dislocation.Methods We analyzed and compared 17 cases of the hip dislocation examined by X-ray and CT.Results X-ray plain film displayed hip joint dislocation in 15 cases,fractures in 10 cases,soft tissue swelling in 9 cases,widened hip joint space in 6 cases and bone fragment in 3 cases after restoration.CT showed hip joint dislocation and fractures in 17 cases,soft tissue swelling in 15 cases,widened hip joint space in 11 cases and bone fragment in 10 cases after restoration.Conclusion For the direction and the degree of hip joint dislocation,acetabulum fracture,bone fragment in articular space and soft tissue swelling,CT has distinct advantage.We find that CT may be one of a routine method in hip joint dislocation,especially after restoration.
