In one hundred and thirteen cases of tuberculosis of the spine for the per o4 o.,thicty-two
I i.1 months, from October 1973 to Jane .1976, at the Department of Orthopedic Surgery, Seoul. Na tional University Hospital, the evaluation of radiological findingsl a_ nd bacteriological results was carried out and the following results-were obtained.
1. The incidence was,high under age of 10. But the shifting of the-prevalent age to. the older was found, especially in 3rd and 4th decades recently.
2. The site of infection was in the lumbar with 45 cases (39.8%), thorayc c 44. cases (39.0 %), thoracolumbar 8 cases (7.1%), lumbosacral 8 cases, and cervical 7 cases (6.2%). The frequent site of: infection was.found in the thoracic region under age of 17 and in the lumbar over age of 18. The average number of the involved vertebrae was .2.6 and the ratio of the affection of two adjacent vertebrae was 55.8%. The commonest mo_ nest site of the -infection cor related with the level of a vertebra was L4 and L5
3. Acid-fast bacilli was confirmed in 24 cases (29.4%) by concentrated direct smear and in 43 cases (52.4%) by culture. The positive finding of biochemical study was resulted in 45 cases (54.9%) by niacin test and in 43 cases (52.4%) by catalase activity.
4. The classical roentgenographic features of tuberculosis of the spine were narrowing of the intervertebral disc space, paravertebral shadow, and collapse of body. However, prior to the appearance of these, osteoporotic change and bone erosion were frequently showed.
