目的::了解性别、年龄对股骨髓腔形态的影响,以指导假体的选择和术中操作,提高假体的远期生存率。方法:选取骨科及放射科各年龄段男、女性病例共500例。采集标准髋关节正位片,应用Onis 2.3软件进行测量,测量股骨近端外部形态参数、髓腔近端径线参数、近端髓腔形态参数共计13个参数,将数据输入SPSS V18.0软件进行分析。结果:股骨近端相关参数与西方人种之间存在显著差异。与欧美人种相比,本组测得偏心距明显较小,而颈干角明显较大(P<0.05),大多数股骨近端髓腔径线参数比欧美人种明显较小(P<0.05)。CFI明显较欧美人种大(P<0.01),Noble分型香槟酒杯型所占比例明显较高,而正常型所占比例较低。31~50岁人群男女股骨近端形态相差最大(P<0.05);0岁以上人群股骨近端形态差异最小(P>0.05)。31~70岁人群男女差异主要表现在股骨头直径、偏心距、峡部位置、峡部内外径以及小结节水平髓腔内径上(P<0.05)。男、女性小粗隆中点下方20 mm水平髓腔内径、峡部髓腔内径、峡部髓腔外径与年龄之间均呈正相关关系(均P<0.01),而股骨近端髓腔形态参数与年龄存在负相关(均P<0.05),而且女性股骨近端髓腔形态参数与年龄的相关程度更高。结论:国人股骨近端相关参数与西方人种之间存在显著差异。男、女性,尤其是女性近端髓腔内径以及峡部内径随年龄增长均逐渐增宽而髓腔形态趋向变直。男女性股骨形态差异随年龄增长有减小的趋势,70岁以上人群男女股骨形态几乎没有差异,31~70岁男性股骨近端髓腔较女性宽而峡部位置较低。
目的::瞭解性彆、年齡對股骨髓腔形態的影響,以指導假體的選擇和術中操作,提高假體的遠期生存率。方法:選取骨科及放射科各年齡段男、女性病例共500例。採集標準髖關節正位片,應用Onis 2.3軟件進行測量,測量股骨近耑外部形態參數、髓腔近耑徑線參數、近耑髓腔形態參數共計13箇參數,將數據輸入SPSS V18.0軟件進行分析。結果:股骨近耑相關參數與西方人種之間存在顯著差異。與歐美人種相比,本組測得偏心距明顯較小,而頸榦角明顯較大(P<0.05),大多數股骨近耑髓腔徑線參數比歐美人種明顯較小(P<0.05)。CFI明顯較歐美人種大(P<0.01),Noble分型香檳酒杯型所佔比例明顯較高,而正常型所佔比例較低。31~50歲人群男女股骨近耑形態相差最大(P<0.05);0歲以上人群股骨近耑形態差異最小(P>0.05)。31~70歲人群男女差異主要錶現在股骨頭直徑、偏心距、峽部位置、峽部內外徑以及小結節水平髓腔內徑上(P<0.05)。男、女性小粗隆中點下方20 mm水平髓腔內徑、峽部髓腔內徑、峽部髓腔外徑與年齡之間均呈正相關關繫(均P<0.01),而股骨近耑髓腔形態參數與年齡存在負相關(均P<0.05),而且女性股骨近耑髓腔形態參數與年齡的相關程度更高。結論:國人股骨近耑相關參數與西方人種之間存在顯著差異。男、女性,尤其是女性近耑髓腔內徑以及峽部內徑隨年齡增長均逐漸增寬而髓腔形態趨嚮變直。男女性股骨形態差異隨年齡增長有減小的趨勢,70歲以上人群男女股骨形態幾乎沒有差異,31~70歲男性股骨近耑髓腔較女性寬而峽部位置較低。

Objective:To evaluate the effect of age and gender on the femoral morphology to guide prosthesis selection in operation and design. <br> Methods:A total of 500 females and males were collected from the departments of orthopedics and medical radiology, Second Xiangya Hospital, Central South University. Informed consent was obtained from all subjects. All patients underwent anteroposterior position scan of the left or right hip joint using Philips Digital Diagnost DR system. The shooting range included the hip joint and at least 2/3 of the proximal femur. The images were measured with Onis 2.3 software. We measured 13 parametersfromthepatients,includingtheexternalparamtersofthefemur,radius-lengthparameters of femoral medullary cavity, and morphological parameters of the femoral medullary cavity. Results:Compared with Westeners, the offset was smaller, while the neck shaft angle was signiifcantly larger in Chinese population (P<0.05). Most parameters of the proximal femoral medul ary cavity diameter were significantly smal er in Chinese population than those in Westerners (P<0.05). The canal lfare index in Chinese population was signiifcantly larger than that in the Westerners (P<0.01). According to the Noble classification, in Chinese population, the proportion of champagne lfute type was signiifcantly larger, while the proportion of standard type was significantly smaller than that in Westerners. There was significant difference in the proximal femur between Chinese population and Westerners. The largest difference of the proximal morphology was presented between males and females in the 31-50 years old people (P<0.05), while the smallest was in the over 70 years old population (P>0.05). The main differences between 31 and 70 years old were the diameter of femoral head, the offset of isthmus, the medullary cavity diameter and extracortical width at isthmus level and the medullary cavity diameter at the level of the lesser trochanter (P<0.05). The modullary transverse diameter at 20 mm below the lesser trochanter and isthmus and extracortical width of isthmus in the male and female group was positively correlated with age (P<0.01), while the parameters of the proximal femoral canal morphology in the female group were negatively correlated with age. The female canal parameters had a stronger correlation. Conclusion:Chinese proximal femoral parameters are signiifcantly different from Westerners. When people, especially females, get older, the medullary cavity diameter of the isthmus and proximal femur becomes wider and the morphology of the femur becomes straight. The difference in the femoral morphology between the male and female decline with the age. There is almost no difference for the over 70 years old. For the 31-70 years old, The male femoral cavity diameter is larger and the position of isthmus is lower than in the females.
