Abstract

Background: The aim of this study is to quantify the changes of the physiological lordosis in the different positions, standing and in ventral decubitus, on a Spinal Surgery Table (SST), and indirectly evaluate the changes in diameter of the different foramina, and measuring the interpedicular distance.
Methods: The study included 20 patients from 20 to 40 years old. X-rays were taken in standing position and on the SST. Lumbar lordosis was measured using the X-rays in the standing position, and on the SST in two positions (low/high), as well as the interpedicular distance of the foramina of each segment.
Results: A loss of lordosis was found in the first position of 22.65º (37.00%) and in the second position of 28.75º (49.14%). An increase was found in the interpedicular distance at all levels in both the low and high position of the SST. The foramina with the greatest opening were the L4-L5 segments, followed by L5-S1.
Discussion: A mean loss of 37.00% and 49.14%, respectively, was found in the physiological lordosis with the use the SST in the two positions used. In all cases there was an increase in the interpedicular distance, which varied between 10% and 15%. The foramina with the greatest openness in the different positions were segments L4-L5 followed by L5-S1. The kyphotisation of the mobile segments would allow a better sacrum-radicular release when increasing the diameter of the channel and the foramina.
