Neutron diffraction has been used to determine the preferred orientation of the hydroxyapatite crystals at the lower front edge of the tibia. The bones are compared for two Neolithic Orkney tribes. At Isbister, a muscular tribe on a hilly site engaged in heavy uphill work, whereas a tribe at Quanterness lived on level ground. The two sets are contrasted with the texture of present-day amputations. Values of 16, 8 and 3 are found for an 'index of manoeuvrability' for the Isbister, Quanterness and modern ankles, respectively.

人骨纹理对生活方式的依赖。

中子衍射已被用于确定在胫骨的下部前边缘处的羟基磷灰石晶体的优选取向。比较了两个新石器时代奥克尼部落的骨骼。在伊斯比斯特（Isbister），山丘上的一个肌肉发达的部落从事繁重的上坡工作，而昆特尼斯（Quanterness）的一个部落居住在平坦的地面上。两组与当前截肢的质地形成对比。分别为Isbister，Quantness和现代脚踝的“可操纵性指数”的值分​​别为16、8和3。
