Objectives. To study kinematics of the lumbosacral spine according to radiometric parameters of the intervertebral joints in patients at the third stage of degenerative-dystrophic process.
Methods. 25 patients with spinal osteochondrosis at the third stage were enrolled in the study. According to the level of localization of the intervertebral discs hernia the main group was divided into two subgroups. In the 1st subgroup 14 (56%) patients with hernia at the level of L4-L5 were included, in the 2nd subgroup – 11 (44%) patients – with lesions of the segment L5-S1. The control group consisted of 12 persons without clinical and anamnestic data about the degenerative process. To study kinematics of the lumbosacral spinal level (LSL) the roentgenography in the lateral projection in the horizontal and vertical position has been performed.
Results. In the 1st subgroup in assessing of radiometric indicators of the intervertebral joints the height reduction of the anterior and posterior sections of the intervertebral disc (IVD) at the level L4-L5 (p<0,05), and the wedge angle of IVD from 9,60 (3,10; 11,10)º to 6,15 (3,10; 9,30)º as well as in the horizontal and vertical positions have been registrered. In the 2nd subgroup the values of the wedge angle of IVD L5-S1 in the horizontal position is significantly lower than in the control group (p=0,04), and verticalization the height of the ventral part of IVD L5-S1 (p<0,05) decreases. Analysis of differences of mean values of the parameters studied showed a reduction of the anterior size of IVD and an increase of interspinous angles in the 1st subgroup at L4-L5 and L5-S1 (p=0,03 and p<0,006, respectively), and in the 2nd subgroup – at L5-S1 (p=0,001 and p=0,04, respectively).
Conclusion. In patients with spinal osteochondrosis in the III stage of the degenerative process the decrease of height was established as well as of the wedge angle of IVD at the the required level. The radiometric patterns of biomechanics disturbances were determined at the radiography of LSL in horizontal and vertical positions.
