Roentgenometry characteristic of thoracic and lumbar spinal fractures according to ct data at different stages of treatment by transpedicular fixation technique

The work is based on analyzing the results of thoracic and lumbar spine roentgen computer tomography, performed in 67 patients at the age of 14-52 years, who were treated at neurosurgery department of Federal State Science Institution -«Russian Ilizarov Scientific Center "Restorative Traumatology and Orthopaedics" of Russian Health Service» for traumatic disease of spinal cord. Computer tomography was performed in 67 patients before treatment, in 54 patients during treatment; there were 31 patients after removal of the device for external transpedicular fixation and 32 patients in the long-term period. The studies made demonstrated as a result that in the long-term period the greatest height decrease was observed in the ventral areas of the intervertebral disc, located caudally relative to the vertebra damaged. There was 60 % deficit of the measurement in comparison with that got by measuring intervertebral disc height in the ventral areas before treatment. In its middle areas the intervertebral disc located cranially relative to the vertebra damaged was second by the degree of height change and deficit (48,3 % decrease of the height before treatment). In the ventral areas the height of the intervertebral disc located cranially relative to the vertebra damaged changed to a lesser extent (46,9 % deficit of the data before treatment). The least changes were determined in the middle areas of the intervertebral disc located caudally relative to the vertebra damaged (26,1 % change).
