Abstract:

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.
