There is increasing evidence that proximal femoral geometry has an important role in the aetiology of hip fractures. We performed a simple radiological study to investigate the relationship between proximal femoral geometry and intracapsular and extracapsular fractures of the proximal femur. Measurements of proximal femoral geometry were made on pelvic radiographs on the contralateral hip of 50 consecutive patients with intracapsular and 50 with extracapsular fractures. The groups were matched for age and sex with a mean age of 79 and a female :male ratio of 4 :1. There were no statistical differences in head diameter, neck width or Head Trochanter Length between the two groups of fractures. Hip Axis Length, neck length and the neck length :width ratio were significantly greater in the intracapsular group, suggesting an aetiological link. This may have implications for future screening and prevention of proximal hip fractures, particularly intracapsular fractures.
越来越多的证据表明，股骨近端几何形状在髋部骨折的病因学中起着重要作用。我们进行了一项简单的放射学研究，以调查股骨近端几何形状与股骨近端囊内和囊外骨折之间的关系。对50例连续的囊内骨折患者和50例囊外骨折患者对侧髋部的骨盆X线片进行股骨近端几何形状测量。两组在年龄和性别上匹配，平均年龄为79岁，女性与男性比例为4:1。两组骨折的头直径、颈宽度或头转子长度无统计学差异。髋轴长度、颈长度和颈长度与宽度之比在囊内组显著更大，提示存在病因学联系。这可能对未来近端髋部骨折尤其是囊内骨折的筛查和预防具有启示意义。
