The distribution of transverse and longitudinal lamellae from osteons and interstitial bone of the two femurs from a woman aged between 25 and 30 was investigated. Exactly plane parallel cross-sections (100 micron) were prepared from the upper, middle and lower thirds of the two bones. The distributions of transverse and longitudinal lamellae was determined for both osteonic and interstitial bone, using circularly polarised light. The results show that (a) as in the male femur, the transverse and longitudinal lamellae in these female femurs have a characteristic rotational distribution along the shaft consistent with the distribution of the bending strains normally operative in bone; and (b) the rotational distribution of the two types of lamellae is slightly asymmetrical in the two female bones, probably because of imperfectly symmetrical use of the lower limbs.
对一名年龄在25至30岁女性的两根股骨中骨单位和骨间骨的横向和纵向骨板分布进行了研究。从两根骨头的上、中、下三分之一处制备了精确的平行平面横截面(100微米)。使用圆偏振光测定了骨单位骨和骨间骨中横向和纵向骨板的分布。结果表明:(a)与男性股骨一样,这些女性股骨中的横向和纵向骨板沿骨干具有特征性的旋转分布,这与正常作用于骨骼的弯曲应变分布一致;(b)在这两根女性骨头中,两种类型骨板的旋转分布略有不对称,可能是由于下肢使用不完全对称。
