The myelography is a important diagnostic measure for the lumbar intervertebral disc herniation but it´s reliability is not absolute. So we attempted to find any correlation between the clinical, radiological and operative findings in the 114 patients who underwent operation following myelography in this hospital for 4 years. The
results were as follows;
1. The rate of male to female was about 2.2 to 1 and the maximum incidence was at the 3rd decade of male and at the 2nd to 4th decade of female.
2. The rate of L4-5 H. N. P. to L5-SI H. N. P. was 3.9 : 1 and this rate is coincident with other reports about korean patients of lumbar intervertebral disc herniation.
3. The positive S. L. R. test was the most frequent neurological finding in these patients.
4. In myelogram, total blocks were 16.7% whereas partial indentation were 83.3% and unilateral filling defect
of smooth round shaped was most frequent(28. 1%). The patient with marked positive S. L. R. test showed
the marked degree of the filling defect in the myelogram.
5. The protruded type was most frequent (67%) in the operative finding. In general the degree of filling defect of myelogram was proportional to the degree of protrusion of disc in the operative findings, with small exception.
6. The filling defect of bilateral wedge shape and unilateral smooth round shape were most frequent in the protruded type and the filling defect of total block and unilateral smooth round shape were most frequent in the extruded type. The shape of filling defect in myelogram do not have any correlation with the degree of protrusion of discs in the operative finding.
7. The degree of positive S. L. R. test was proportional to the degree of protrusion of discs in these patients. 8. In general, the degree of protrusion of disc in operative finding was proportional to both the severity of clinical finding and the degree of filling defect in myelogram.
Therefore the operative indication of lumbar intervertebral disc herniation should be based upon both the clinical and myelographic findings.
