Foraminal changes with distraction and compression of the L4/5 and L5/S1 segments.

Abstract

The width of the foramen in the lumbar spine is directly related to the position of the vertebrae. In an MRI study the measurements of the cross-sectional area of the neuroforamen of L4/5 and L5/S1 in neutral position, segmental distraction and compression were calculated. Nine cadaver specimens were investigated and the foraminal width of L4/5 and L5/S1 was measured. In both segments of all specimens the foraminal space significantly enlarged under distraction and decreased under compression. In the L4/5 segment the average relative difference between distraction and compression was 27%.
