目的 探讨CR系统在股骨颈骨折成像中的临床实用价值。方法 选择 108例股骨颈骨折病人进行CR检查,并与同时期常规X线屏 /胶平片进行对照分析。结果 本组 108例病人,在骨外科Garden4种分型中 [1],CR系统能全部清晰显示各型骨折线,而常规X线屏 /胶平片 3例Ⅰ型、5例Ⅱ型未见明显异常。2种方法阳性检出率,在统计学上有显著差异。结论 CR系统利用其后处理功能,可以及时诊断各型股骨颈骨折,尤其在Ⅰ、Ⅱ型方面,优于常规X线屏 /胶平片。
Objective To investigate the clinical value of CR system in the imaging of femoral neck fracture. Methods A total of 108 patients with femoral neck fracture were selected for CR examination and compared with conventional X-ray / plastic plain film in the same period. Results 108 cases of this group of patients in the orthopedic Garden4 kinds of classification [1], CR system can clearly show all types of fracture line, and conventional X-ray / plastic film in 3 cases of type Ⅰ, 5 cases of type Ⅱ did not see Obvious abnormalities. Positive detection rate of the two methods, statistically significant differences. Conclusion The CR system can diagnose all kinds of femoral neck fractures in time by using its post-processing function, especially in type Ⅰ and type Ⅱ, which is better than conventional X-ray and plastic sheeting.
