Correlation of degenerative-dystrophic changes in VMS based on classic roentgen indexes of pre- and post-operation periods did not show any distinctions among the observed patients.
While applying DECT showed quite different picture.
Two patient groups had differences in post-operation period,
which we can see in table 1 and table 2.
The patients with dynamic stabilizing systems had minimal trabecular substance changes in vertebral bodies and articular processes or did not have any: Ca reduction per volume unit within [0- 10] ME 6mg,
increase of adipose tissue quantity [11-23] 16mg,
H2O reduction per volume unit in adjacent intervertebral disks also were minimal – [0- 45] ME 25.
Post-operation time for the patients with rigid VMS stabilization saw more evident DDC than pre-operation time: trabecular substance change of vertebral body and articular process- in Ca reduction per volume unit [12-22] ME 14mg,
increase of adipose tissue quantity [28-51] ME 38mg.
In adjacent intervetebral disks H2O is reduced [45-80] ME 60mg.
These changes prove much more sweeping DDC development and some signs of adjacent disk syndrome during early post-operation time.
