Abstract
A 9- to 12-year follow-up review was conducted in 105 of 124 patients who were treated with chymopapain chemonucleolysis for herniated lumbar disc. The data were obtained from responses to a questionnaire. Seventy-nine patients (75.2%) reported marked improvement, six (5.7%) had slight improvement, and 20 (19.0%) had no improvement. Of the 87 patients not receiving workman's compensation, 70 patients (80.5%) had marked improvement; four (4.6%) had slight improvement; and 13 (14.9%) had no improvement. Of the 18 compensation cases, nine patients (50.0%) had marked improvement; two patients (11.1%) had slight improvement; and seven patients (38.9%) had no improvement. These results are comparable to those reported for surgical discectomy, and confirm that chymopapain chemonucleolysis is an alternative to surgery.
