OBJECTIVE: The authors retrospectively evaluate the benefits of the various pain procedures for the treatment of low back pain unresponsive to conservative management. METHODS: Over a period of 2 years from May 2002 and June 2004, the authors had performed various pain procedures on 106 patients with low back pain. Epidural block, facet joint block, sacroiliac joint block, and myofascial block were included among various pain procedures. The pain improvement, period of analgesic use, and degree of satisfaction were evaluated 1 day, 4 weeks, and 6 months after injections. The outcome of pain procedures was analyzed by using a modified Macnab criteria. RESULTS: Sixty-four patients had a single procedure with no combination and 42 patients (39.6%) received the combination of the various pain procedure. Regardless of the single or combination cases of procedure, combination of appropriate spinal level on each procedure was conducted in 104 (98.1%). Mean follow up period was 12.2 months. Eighty-two patients (77.4%) experienced significant pain relief and overall analgesic medication was reduced in 91 patients (85.8%) at 6 months after procedure. Unfavorable results were demonstrated in 10 patients. Permanent procedural complications did not occur. CONCLUSION: The various pain procedures are the possible therapeutic option for low back pain unresponsive to conservative management including medication or physical therapy.
