This may be interpreted as follows: 68% of examiners' findings for the most-fixated segment were [less than or equal to] 3.34cm apart, which is equivalent to 83.5% of the height of one lumbar vertebra. Thus the examiners had a 68% chance of agreeing on the most-fixated level, or at least the motion segment (consisting of 2 vertebra) including it.

According to our data, the so-called Johnson-Thompson index (ratio of the size of the sagittal spinal canal to the sagittal vertebral body size) from the first through fifth lumbar vertebral segment is in the range from 1:1.88 to 1:1.74 to the level of lumbar vertebra; i.e.

Abstract: The paper presents a finite element analysis of three insertion directions of pedicle screw in lumbar vertebra, the purpose being to investigate the impact of the implantation trajectory over the stability of vertebral pedicle-screw interface, by comparing the maximal displacements obtained for the same pull-out force.

The differences were significant at the femur and first lumbar vertebra, but not at the other lumbar measurements.
