不同物种髋臼的骨小梁方向

背景：有研究认为骨的形态结构与其所处的应力环境密切相关。由于人类直立行走的运动方式，可能会影响髋臼骨小梁的方向。 目的：观察不同物种髋臼骨小梁方向的差异。 方法：X射线观察由解放军第二军医大学解剖教研室和山东大学生命科学院提供的成人双侧髋骨干燥标本和成年恒河猴髋骨标本，将采集到的图像输入Imagine pro plus 6.0，经快速傅里叶变换后，得出0°-180°的频谱值，计量不同的角度骨小梁的数量。 结果与结论：人类髋骨在0°及90°频谱值最大，与骶耻束与髂坐束的方向符合。而恒河猴髋骨的频谱值分布较为弥散，没有明显的峰值。说明人类髋臼区域骨小梁主要沿90°及180°方向分布，与特化的骶耻束与髂坐束的方向符合，说明髂坐束的出现是与直立行走密切相关的。

Acetabular trabecular direction between different species

BACKGROUND: Some studies have shown that the morphological structure of bone is closely related with the stress environment. But the human walking upright movement may affect the direction of the acetabular trabecular bone. OBJECTIVE: To observe the differences of acetabular bone direction between different species. METHODS:Hip bones of human and rhesus monkey selected from Department of Anatomy, Second Military Medical University and the Shandong University School of Life Science were scanned by X-ray under the same conditions of shooting. The images were imported into Imagine pro plus 6.0 and transferred by fast fourier transform, then obtained the spectrum value of 0°-180° to calculate the number of trabeculae in a certain direction.    RESULTS AND CONCLUSION:The human had highest spectrum value in 0° and 90° which were in accordance with Ilioischial bundle and sacropubic bundle. Rhesus monkeys distributed dispersedly and there was no obvious peak. The human trabecular in acetabular region mainly distributed along 90°-180° which were in accordance with Ilioischial bundle and sacropubic bundle, this indicated that there was relationship between Ilioischial bundle and human walking pattern.
