The usefulness of peridural and facet blocks has been controversial in the management of pain in patients with pathology of the spine, being used only as a last resort. For this work we collected 50 patients between January 2005 and January 2006 at the Hospital Universitario Clínica San Rafael de Bogotá. There were separated in 3 groups based on their pathology. The first group included 34 patients with a herniated disc and the second group 9 patients with a narrow lumbar canal who received epidural block, and the third group with facet disease received a facet block. To determine the result of the blocks, we evaluated the improvement in the pain, the return to laboral activity, the use of adjuvant analgesics and the need for surgical intervention. The pain improvement was 71,5% for those patients with facet disease, 77.7% for those patients with a narrow canal and 65% for those with a herniated disc. The percentage of return to laboral activity was similar in the three groups, 85,7% for patients with facet disease, 67% for patients with a narrow canal and 73,5% for patients with a herniated disc. Adjuvant analgesics were required by 42,9% of the patients with facet disease, 55,5% of the patients with a narrow lumbar canal and 29,5% of the patients with a herniated disc. Surgery was necessary in 11% of the patients with a narrow canal and 14% of the patients with a herniated disc. Patients with facet disease did not require surgery. In view of the efficacy of the blocks above 50% for all of the measured parameters, it is proposed that the blocks should always be attempted prior to the use of more invasive methods.
