64排螺旋CT对股骨颈骨折分型的临床价值

目的评价64排螺旋CT在股骨颈骨折分型中的临床价值。方法回顾分析46例股骨颈骨折行X线检查及CT容积扫描的影像学资料,分别进行Garden分型;按照修正的分型方法（移位型与非移位型）,比较两种影像学检查方法的差异。结果 X线检查组GardenⅠ型2例,Ⅱ型10例,Ⅲ型22例,Ⅳ型12例;CT检查组GardenⅠ型1例,Ⅱ型4例,Ⅲ型26例,Ⅳ型15例。46例股骨颈骨折的CT组与手术所见符合率为100%。以修正的分型方法为依据,CT组Garden分型优于X线组（P〈0.05）。结论以64排螺旋CT为基础的Garden分型提高了分型的准确性,具有更好的临床应用价值。

Clinical Value of 64-Slice Spiral CT for Classification of Femoral Neck Fracture

Objective To evaluate the clinical application of 64-slice spiral CT for classification of femoral neck fracture.Methods The survey was comprised of 46 patients with femoral neck fractures detected with plain radiographs and CT images.Cases were randomly presented in 2 formats：plain radiographs and CT.Garden classification was queried.Modification of garden classification（nondisplaced vs displaced） was taken to compare with plain radiographs and CT in the study.Results The results of classification for plain radiographs were 2 cases of Garden Ⅰ,10 cases of Ⅱ,22 cases of Ⅲ,and 12 cases of Ⅳ.Those for CT were 1 cases of Garden Ⅰ,4 cases of Ⅱ,26 cases of Ⅲ,and 15 cases of Ⅳ.CT improved the accuracy of Garden Classification（P0.05）.Conclusion Garden classification using CT images showes good conformation with results of surgey.64-Slic CT is better than plain radiographs for Garden classification of femoral neck fracture.
