摘要：

背景：虽然目前已采用多种力学研究方法对骨盆的力学特性进行了大量的研究，但是该区域的确切应力分布仍不甚明了。
目的：观察髋臼区域骨小梁的大体分布状况并与现有生物力学研究结果对比。
方法：采用4具干燥骨盆标本，取其两侧髋骨分别按照髋臼边缘构成的平面及闭孔平面进行切割，观察其切面的骨小梁分布模式以了解了解髋臼区域骨小梁的大体分布状况。
结果与结论：髋骨骨小梁可分为：①骶耻束：从耳状面及髂后上棘髂后下棘发出沿弓状线到达耻骨联合，部分骨小梁终止于髋臼后上方。②髂臼束从从耳状面坐骨大切迹发出到达髋臼后上部，位于骶耻束浅层。③髂坐束：从髂结节发出到达坐骨结节，部分骨小梁终止于髋臼前上方。其中骶耻束与髂坐束相交于臼顶，在坐骨大切迹、髂耻隆起及骶耻束与髂坐束相交部位骨质致密。总体上人类髋骨骨小梁主要由髂臼束、骶耻束与髂坐束构成。在坐骨大切迹、髂耻隆起及骶耻束与髂坐束相交部位骨质致密。这与现有研究中髋臼区域的应力分布负荷基本吻合。

Abstract:

BACKGROUND: Although a variety of mechanics study on the mechanical characteristics of the pelvis has been performed, but the exact stress distribution in the region remains unclear.
ONJECTIVE: To observe the gross distribution of bone trabecula around acetabulum and compare with existing biomechanical research results.
METHODS: Four dry pelvic specimens were cut in accordance with the plane which composed of acetabular edge and the plane of obturator in order to observe the distribution patterns of trabecular bone on the cross-section, and to observe the gross distribution of trabecula around acetabulum.
RESULTS AND CONCLUSION: The trabeculae of hip bone were divided into three groups. ①Sacropubic bundle: It ran from the auricular surface, posterior superior iliac spine and posterior inferior iliac spine to pubic symphsis along the iliopectinal line, and part of the trabecula terminated in the posterior superior acetabular. ②Iliocotyloid bundle: It ran from the greater sciatic notch of the auricular surface to the superior posterior acetabular, and located in the shallow layer of the sacropubic bundle. ③Ilioischial bundle: From the region of the iliac crest to the ischial tuberosity, part of the trabecula terminated in the anterior superior acetabular. High-density trabecular net transversely located at the level of the sciatic notch, defined by a distinct saltire-shaped crossing over the acetabulum between the sacropubic and the ilioischial bundles. The human hip acetabulum was constituted by iliocotyloid bundle, sacropubic bundle and ilioischial bundle. High-density trabeculum net transversely located at the level of the sciatic notch, iliopubic eminence and the cross-section of sacropubic and the ilioischial bundles. This is consistent with the stress distribution and loading of the acetabular region in the current research.
