We studied the morphology of the contralateral femur in 10 patients with subcapital fractures, 10 with trochanteric fractures and 10 with unilateral osteoarthritis. We found that the patients with trochanteric fractures had a significantly shorter femoral neck (4.5 +/- 0.5 cm) than patients with subcapital fractures or osteoarthritis (5.4 +/- 0.4 cm). It may be that this difference in femoral neck length is related to the site at which a proximal femoral fracture occurs.
我们研究了10例股骨头下骨折患者、10例转子间骨折患者和10例单侧骨关节炎患者对侧股骨的形态。我们发现，转子间骨折患者的股骨颈（4.5±0.5厘米）明显短于股骨头下骨折患者或骨关节炎患者（5.4±0.4厘米）。股骨颈长度的这种差异可能与股骨近端骨折发生的部位有关。
