| 目的 通过测量内蒙古地区蒙古族、汉族健康人群股骨近端骨密度及骨结构相关几何力学参数，探讨本地区蒙古族、汉族股骨近端骨密度及骨结构相关几何力学参数随性别、年龄变化的规律。方法 从DXA工作站中选出本次研究需要的1000人次骨密度检查报告，其中蒙古族500例，汉族500例，利用DXA系统中配置的骨科高级专用软件分析股骨近端几何力学参数。结果 蒙古族、汉族男女性别各部位出现骨峰值的年龄段略有不同，二者均表现为年龄愈大，骨密度值愈低(p<0.01)，蒙古族男、女股骨近端CSMI、CSI随年龄增长均逐渐降低(p<0.05)，HAL 、FNW未见与年龄和性别的变化有关(p>0.05)，女性FSI和NSA随年龄增高而下降(p<0.05)，而男性的FSI和NSA未见年龄性变化(p>0.05)。汉族男性股骨近端几何力学参数同当地蒙古族无显著差异，汉族女性股骨近端几何力学参数与当地蒙古族女性有显著性差异(p<0.05)，即随年龄增高NSA略大，HAL略长，FNW略宽。结论 蒙古族、汉族股骨近端骨密度随性别、年龄变化各有其特点，但随年龄增长骨密度值均逐渐降低，股骨近端几何力学参数随性别、年龄变化有差异性。 |

| Objective To explore the rule of the changes of bone mineral density (BMD) and the related geometric and mechanical parameters of the proximal femur by gender and age in Mongolian and Han people in the area, by measuring their BMD and geometric and mechanical parameters of the proximal femur. Methods BMD results of 1000 people from the DXA work station were selected, including 500 cases of Mongolian and 500 cases of Han nationality. Geometric and mechanical parameters of the proximal femur were analyzed using advanced orthopedics software configured in the DXA system. Results The peak bone mass appeared in Mongolian and Han were different in age. The older the age was, the lower the BMD (P<0.01). CSMI and CSI of the proximal femur decreased along with aging in Mongolian males and females. HAL and FNW appeared no change in gender and age (P>0.05). FSI and NSA decreased with aging in the female (P<0.05) but not in the male (P>0.05). The geometric mechanics parameters of the proximal femur were not different in males between Han and local Mongolian. They were significantly different in females between Han and local Mongolian (P<0.05). NSA, HAL, and FNW slightly increased along with aging. Conclusion BMD of the proximal femur in Mongolian and Han has its own characteristics in gender and age. BMD decreases with the growth of age. The geometry parameters of the proximal femur are different in gender and age. |
