【摘要】 目的 :测定中老年国人正常股骨近端形态解剖参数,为关节置换患者拟定术前计划和假体选择提供参考。方法:收集2017年2月～12月入住北京解放军总医院骨科医院,髋关节正常而膝关节退变行全膝置换病例共260人,用医学影像软件测定并记录股骨近端关键解剖数据,与其他测量结果比较其统计学差异,并探讨性别、年龄对股骨近端髓腔解剖结构的影响。结果 :中老年国人股骨近端解剖学参数除了股骨髓腔闪烁指数(CFI)值外,其他数据与西方人种差异均有统计学意义。在CFI分型中烟囱型髓腔比例较普通国人及西方人群高。年龄是CFI的影响因素,峡高比(峡部高度/股骨全长)均值为0.25。结论 :中老年国人和西方人群的股骨近端解剖参数存在明显差异,烟囱型髓腔比例较普通国人及西方人群高,假体选择时需要考虑年龄因素,股骨峡部多出现在股骨全长的近1/4处。更多还原

【Abstract】 Objective :The morphological and anatomical parameters of normal proximal femur in middle-aged and elderly Chinese were measured to provide reference for the preoperative planning and prosthesis selection of joint replacement patients. Methods :A total of 260 cases of total knee replacement with normal hip joint and degenerative knee joint were collected from February to December in 2017, and the key anatomical data of proximal femur were measured and recorded by medical imaging software. The statistical differences were compared with other measurement results, and the effects of gender and age on the anatomical structure of proximal femur medullary cavity were discussed. Results :The anatomical parameters of proximal femur of middle-aged and elderly Chinese were statistically different from those of Westerners except femoral marrow canal flare index( CFI). In CFI classification, the proportion of chimney-shaped medullary cavity was higher than that of Chinese and western people. Age was the factor influencing CFI, and the isthmus height ratio( isthmus height/femur length) was 0.25 on average. Conclusion : There are significant differences in anatomical parameters of proximal femur between middle-aged and elderly Chinese and Western people, and the proportion of chimney-shaped medullary cavity is higher than that of ordinary Chinese and Western people. Therefore, age should be taken into account when selecting prosthesis, and most of the femoral isthmus occurs in nearly a quarter of the length of the femur.更多还原
