The role of proximal femur morphology to the development of certain proximal femur fracture types both femoral neck and trochanteric fractures has been observed. However, the relavance of acetabular morphology to the development of proximal femur fractures is not extensively questioned. Therefore the aim of the study was to determine whether there is a correlation between acetabular morphology and pathogenesis of 2 different hip fracture types after low energy trauma.
This retrospective study includes 60 cases (41 women, 19 men) with a proximal femoral fracture after a low energy trauma between July 2012 and December 2014. Acetabular depth and acetabular index were measured on pelvic radiographs. Neck shaft angle, hip axis length and cortical index were measured on pelvic computed tomography scans. All measurements were performed on the contralateral hip.
Mean age was 77.56 ± 8.99 years (range 61-92 years). No statistically significant difference was found with regard to neck shaft angle, acetabular depth or cortical index measurements between patients with femoral neck fracture and patients with trochanteric femoral fractures (p>0.05). Acetabular index measurement was higher (p = 0.001) and hip axis length measurement was lower (p = 0.001) in trochanteric fracture group as compared to femoral neck fracture.
The rate of trochanteric femur fractures is higher in patients with high acetabular index, whereas the rate of femoral neck fractures is higher in patients with increased hip axis length.
已观察到股骨近端形态对某些股骨近端骨折类型（包括股骨颈骨折和转子间骨折）发生发展的作用。然而，髋臼形态与股骨近端骨折发生发展的相关性尚未受到广泛质疑。因此，本研究的目的是确定低能量创伤后髋臼形态与两种不同类型髋部骨折发病机制之间是否存在关联。
本回顾性研究纳入了2012年7月至2014年12月期间因低能量创伤导致股骨近端骨折的60例患者（41例女性，19例男性）。在骨盆X光片上测量髋臼深度和髋臼指数。在骨盆计算机断层扫描上测量颈干角、髋轴长度和皮质指数。所有测量均在对侧髋部进行。
平均年龄为77.56±8.99岁（范围61 - 92岁）。股骨颈骨折患者和转子间股骨骨折患者在颈干角、髋臼深度或皮质指数测量方面未发现统计学上的显著差异（p>0.05）。与股骨颈骨折相比，转子间骨折组的髋臼指数测量值更高（p = 0.001），髋轴长度测量值更低（p = 0.001）。
髋臼指数高的患者转子间股骨骨折发生率较高，而髋轴长度增加的患者股骨颈骨折发生率较高。
