To study results of surgical treatment for spinal canal stenosis in patients with degenerative-dystrophic diseases of the cervical and lumbar spine. Material and Methods. Complex pre-and postoperative examination of 56 patients with congenital and/or acquired spinal canal narrowing was performed. Clinical diagnosis was based on findings of neurological and orthopedic examination, X-ray investigation, spiral CT, MRI, Doppler sonography, and electroneuromyography. Treatment results were assessed at discharge and at 6 months after surgery. Immediate and longterm indices of pain syndrome intensity, vertebroneurological semiology, and scores of Oswestry Low Back Pain Disability Questionnaire and of Neck Disability Index were compared. Results. We succeeded in significant decrease in pain intensity in most patients; the score of pain sense at discharge was 1 to 3. At follow-up after 6 months 30 patients had no radicular pain, 26-had unpleasant pain senses, though transient, with intensity score of 3 to 4. Conclusion. The choice of access, volume and nature of surgical exposure should be planned based on consideration of all factors promoting development of myeloradiculopathy. The cervical spine is operated using predominantly anterior decompression and stabilizing procedures, the lumbar spine-using posterior procedures. The choice of spine stabilization method depends on instability causes, degree of displacement and mobility of vertebrae.

To measure the volumes of health and degenerated intervertebral foramina and to analyze correlation between the obtained data and clinical presentation of disease. Material and Methods. Intervertebral foramen volume was measured in 227 patients with bilateral degenerative disease in the cervical (89), thoracic (28), and lumbar (110) spine, using spiral computed tomography. Bone and soft tissue components of the foramen determined the volume loss in comparison with the opposite side. The loss was considered moderate if the volume decreased by 15��0 �� as evidenced by at least ��0 �� as evidenced by at least �0 �� as evidenced by at least one component, marked � by �1��0 �� and significant � by ��0 �� and significant � by �0 �� and significant � by more than �0 ��. Results. The volume of intervertebral foramina at all spinal levels in men exceeded that in women. Essential and statistically reliable differences between indicators at both sides were revealed neither in men, nor in women. Correlation between a foramen volume and a patient's height was revealed: height increase was associated with volume accrual. Direct correlation between indices of intervertebral foramen volume, pain syndrome intensity, and radiculopathy severity was observed. Conclusions. CT-assisted measurement of intervertebral foramen volume enables determining the rate of its loss from both bone and soft-tissue components. As well as any other results of additional investigation, digital parameters should be estimated in a complex, taking into account clinical presentation of disease.
