Abstract:
The were studied 168 intervertebral foramina on the levels L4 to L5 and L5 to S1 as well as the thickness of the spinal nerve by application of the planimetric method. An index of the tightness of the intervertebral foramina has been established. The narrowness of intervertebral foramina has been found to occur much more frequently on the right side of both of the tested levels, what is the reason of increased occurrence of lumbosacral syndrome of pain on this side.
