The orientation of the superior articular processes with regard to the upper end-plate of the sacrum does not depend on the inclination of the sacrum. This assertion can be made by interpreting certain angles already described in literature and may be confirmed by a research following strict biomechanic principles: The orientation of the articular processes is put in relation to the direction of the forward shear brought upon by the Vth lumbar vertebra and caused by the inclination of the sacrum. This is achieved by measuring the angle between the articular facet and a plane normal to the mentioned forward shear. The result is that the size of this angle does not at all depend on the degree of the inclination of the sacrum.
骶骨上关节突相对于骶骨上端板的方向并不取决于骶骨的倾斜度。这一论断可通过对文献中已描述的某些角度进行解读得出，并且可能会被一项遵循严格生物力学原理的研究所证实：关节突的方向与第五腰椎因骶骨倾斜而施加的向前剪切力的方向相关。这是通过测量关节面与垂直于上述向前剪切力的平面之间的角度来实现的。结果是，这个角度的大小完全不取决于骶骨的倾斜程度。
