| 目的 探讨CT对股骨近端几何形态的评估价值,以及股骨近端几何形态与髋部脆性骨折的相关性.方法 对33例股骨颈骨折和38例粗隆间骨折老年妇女,应用CT扫描股骨近端,并测量颈干角、股骨颈轴长、股骨头直径和股骨颈直径.结果 在不同骨折组间,颈干角差异有显著相关性(P＜0.01).股骨颈轴长、股骨头直径与股颈直径呈正相关(P均＜0.01),在不同的骨折组间三者差异没有显著相关性(P＞0.05).结论 利用CT分析股骨近端几何形态,操作简单、精确性高.颈干角与髋部骨折的类型有显著相关性,颈干角越小易发生股骨颈骨折,而颈干角越大更易发生粗隆间骨折. |

| Abstract：0bjective To explore the value of computerized tomography(CT)for the assessment of proximal femoral geometry，and to investigate the relationship between proximal femoral geometry and the hip fragility fractures．Methods The proximal femur was screened using CT in 33 cases of the femoral neck fractures and 38 cases of the trochanteric fractures in elder women.The neck-shaft angle(NSA),hip axis length(HAL),femoral head diameter (FHD),and femoral neck diameter(FND)were measured.Results Significant differences in NSA were found among the fracture groups(P<0.01).HAL and FHD were positively correlated with FND(P<0.01).There was no significant difference of the three parameters among the fracture groups (P>0.05) .Conclusion CT assessment for proximal femora geometry was simple and precise．NSA was significantly correlated with the type of hip fracture．The less the NSA，the more femoral neck fractures might happen．The larger the NSA，the more trochanteric fractures might happen． |
