[Personal experience with surgical treatment of the lumbo-ischiadic syndrome]

A prospective investigation of 200 patients with lumboischiadic syndrome, who were operated in the Regional Institute of National Health, Banska Bystrica. Before operation 176 patients had CT examinations and 70 perimyelographic examinations. Only patients where the clinical finding and CT or perimyelographic finding correlated were indicated for operation. Attention was focused on comparison of the findings on operation and findings of the CT examination. Noninvasive CT examinations which are aimed and follow a detailed clinical analysis and incl. sagittal reconstruction pictures give a reliable idea of morphological changes in the examined LS portion of the spine. They make it possible to localize herniation of intervertebral disc and to differentiate reliably compression of spinal roots by osseous structure in the area of facet, the narrow lateral recess or narrow spinal canal. Thus selective surgery is possible. Invasive perimyelographic examination is the method of choice where CT is not available or when the CT finding does not correlate with the clinical finding.
