Clinical and ultrastructural analysis of failures in chemonucleolysis.
A series of 12 patients with failed chemonucleolysis were analyzed to determine the various causes of such failures. The ultrastructural findings observed in laminectomy specimens did not account for the failure in the enzyme treatment. The findings suggested deficient cellular nutrition secondary to enzymatic histolysis of the nucleus pulposus.
