We have experienced the 43 cases of HIVD patient treated with chemonucleolysis from July, 1987 to december, 1992. The evaluation Criteria for final outcome was Marked. Slight, and Un-improvement by Van Leeuwen et al. We analysed the data by
symptom
duration, and by number of criteria by McCulloch.
Among the patients with symptom duration below 6 months, the symptom improvement was achived in 96%, and the patients who have 4 or 5 diagnosis criteria gained symptom improvement in 90%, Symptom improvement was observed in 81% of cases with the
follow
up period more than one year.
As compaired with conventional laminectomy, the chemonucleolysis is noninvasive, and has low morbidity & mortality rate than laminectomy, and nearly equal success rate, when the procedure is done by experienced surgeon, and by accurate mothed in
proper
candidate.
