The authors carried out measurements of 168 intervertebral foramina on the level L4 to L5 and L5 to S1 as well as the thickness of the spinal nerve, and examined their form. They certified that the measurements of the intervertebral foramen L5 to S1 are really statistically lower as the measurements of the intervertebral foramen L4 to L5 at relatively the same average thickness of the spinal nerve.
作者对L4至L5以及L5至S1水平的168个椎间孔进行了测量，并测量了脊神经的厚度，同时检查了它们的形态。他们证实，在脊神经平均厚度相对相同的情况下，L5至S1椎间孔的测量值在统计学上确实低于L4至L5椎间孔的测量值。
