Background: Lumbar facet joints have been implicated as the source of chronic pain in 15% to 45% of patients with chronic low back pain. Various therapeutic techniques including intraarticular injections, medial branch blocks, and radiofrequency neurotomy of lumbar facet joint nerves have been described in the alleviation of chronic low back pain of facet joint origin. Objective: The study was conducted to determine the clinical effectiveness of therapeutic local anesthetic lumbar facet joint nerve blocks with or without steroid in managing chronic function-limiting low back pain of facet joint origin. Design: A randomized, double-blind, controlled trial. Setting: An interventional pain management setting in the United States. Methods: This study included 60 patients in Group I with local anesthetic and 60 patients in Group II with local anesthetic and steroid. The inclusion criteria was based on the positive response to the diagnostic controlled comparative local anesthetic lumbar facet joint blocks. Outcome measures: Numeric pain scores, Oswestry Disability Index, opioid intake, and work status. All outcome assessments were performed at baseline, 3 months, 6 months, and 12 months. Results: Significant improvement with significant pain relief (> 50%) and functional improvement (> 40%) were observed in 82% and 85% in Group I, with significant pain relief in over 82% of the patients and improvement in functional status in 78% of the patients. Based on the results of the present study, it appears that patients may experience significant pain relief 44 to 45 weeks of 1 year, requiring approximately 3 to 4 treatments with an average relief of 15 weeks per episode of treatment. Conclusion: Therapeutic lumbar facet joint nerve blocks, with or without steroid, may provide a management option for chronic function-limiting low back pain of facet joint origin.

Background: Lumbar facet joints are a well recognized source of low back pain and referred pain in the lower extremity in patients with chronic low back pain. Conventional clinical features and other non-invasive diagnostic modalities are unreliable in diagnosing lumbar zygapophysial joint pain. Controlled diagnostic studies with at least 80% pain relief as the criterion standard have shown the prevalence of lumbar facet joint pain to be 16% to 41% of patients with chronic low back pain without disc displacement or radiculitis, with a false-positive rate of 17% to 49% with a single diagnostic block. Study Design: A systematic review of the diagnostic accuracy of lumbar facet joint nerve blocks. Objective: To determine and update the diagnostic accuracy of lumbar facet joint nerve blocks in the assessment of chronic low back pain. Methods: A methodological quality assessment of included studies was performed using Quality Appraisal of Reliability Studies (QAREL). Only diagnostic accuracy studies meeting at least 50% of the designated inclusion criteria were utilized for analysis. Studies scoring less than 50% are presented descriptively and analyzed critically. The level of evidence was classified as good, fair, and limited or poor based on the quality of evidence developed by the United States Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to June 2012, and manual searches of the bibliographies of known primary and review articles. Outcome Measures: Studies must have been performed utilizing controlled local anesthetic blocks. Pain relief was categorized as at least 50% pain relief from baseline pain and the ability to perform previously painful movements. Results: A total of 25 diagnostic accuracy studies were included. Of these, one study evaluated 50% to 74% relief as criterion standard with a single block with prevalence of 48%, 4 studies evaluated 75% to 100% relief as the criterion standard with a single block with a prevalence of 31% to 61%, 5 studies evaluated 50% to 74% relief as the criterion standard with controlled blocks with a prevalence of 15% to 61%, and 13 studies evaluated 75% to 100% relief as the criterion standard with controlled blocks with a prevalence of 25% to 45% in heterogenous populations. False-positive rates ranged from 17% to 66% in the 50% to 74% pain relief group and 27% to 49% with at least 75% relief as the criterion standard. Based on this evaluation, the evidence showed that there is good evidence for diagnostic facet joint nerve blocks with 75% to 100% pain relief as the criterion standard with dual blocks and fair evidence with 50% to 74% pain relief as the criterion standard with controlled diagnostic blocks; however, the evidence is poor with single diagnostic blocks of 50% to 74%, and limited for 75% or more pain relief as the criterion standard. Limitations: The shortcomings of this systematic review of the accuracy of diagnostic lumbar facet joint nerve blocks include a paucity of literature and continued debate on an appropriate gold standard. Conclusion: There is good evidence for diagnostic facet joint nerve blocks with 75% to 100% pain relief as the criterion standard with dual blocks, with fair evidence with 50% to 74% pain relief. Key words: Chronic low back pain, lumbar facet or zygapophysial joint pain, facet joint nerve blocks, medial branch blocks, controlled comparative local anesthetic blocks

Background: The prevalence of persistent low back pain with the involvement of lumbar facet or zygapophysial joints has been described in controlled studies as varying from 15% to 45% based on the criteria of the International Association for the Study of Pain. Therapeutic interventions utilized in managing chronic low back pain of facet joint origin include intraarticular injections, medial branch nerve blocks, and neurolysis of medial branch nerves. Objective: To determine the clinical effectiveness of therapeutic lumbar facet joint nerve blocks in managing chronic low back pain of facet joint origin. Design: A prospective, randomized, double-blind trial. Setting: An interventional pain management setting in the United States. Methods: In this preliminary analysis, data from a total of 60 patients were included, with 15 patients in each of 4 groups. Thirty patients were in a non-steroid group consisting of Groups I (control, with lumbar facet joint nerve blocks using bupivacaine ) and II (with lumbar facet joint nerve blocks using bupivacaine and Sarapin); another 30 patients were in a steroid group consisting of Groups III (with lumbar facet joint nerve blocks using bupivacaine and steroids) and IV (with lumbar facet joint nerve blocks using bupivacaine, Sarapin, and steroids). All patients met the diagnostic criteria of lumbar facet joint pain by means of comparative, controlled diagnostic blocks. Outcome Measures: Numeric Rating Scale (NRS) pain scale, the Oswestry Disability Index 2.0 (ODI), employment status, and opioid intake. Results: Significant improvement in pain and functional status were observed at 3 months, 6 months, and 12 months, compared to baseline measurements. The average number of treatments for 1 year was 3.7 with no significant differences among the groups. Duration of average pain relief with each procedure was 14.8 ± 7.9 weeks in the non-steroid group, and 12.5 ± 3.3 weeks in the steroid group, with no significant differences among the groups. Conclusion: Therapeutic lumbar facet joint nerve blocks with local anesthetic, with or without Sarapin or steroids, may be effective in the treatment of chronic low back pain of facet joint origin. Key words: Chronic back pain, lumbar facet joint pain, lumbar zygapophysial joint pain, medial branch blocks, therapeutic lumbar facet joint nerve blocks, local anesthetic.

Background: Therapeutic lumbar facet joint interventions are implemented to provide long-term pain relief after the facet joint has been identified as the basis for low back pain. The therapeutic lumbar facet joint interventions generally used for the treatment of low back pain of facet joint origin are intraarticular facet joint injections, lumbar facet joint nerve blocks, and radiofrequency neurotomy. Objective: To evaluate and update the effect of therapeutic lumbar facet joint interventions in managing chronic low back pain. Study Design: A systematic review of therapeutic lumbar facet joint interventions for the treatment of chronic low back pain. Methods: The available literature on lumbar facet joint interventions in managing chronic low back pain was reviewed. The quality assessment and clinical relevance criteria utilized were the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials and the criteria developed by the Newcastle-Ottawa Scale criteria for observational studies. The level of evidence was classified as good, fair, and limited or poor based on the quality of evidence developed by the U.S. Preventative Services Task Force. Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 through June 2012, and manual searches of the bibliographies of known primary and review articles. Outcome Measures: The primary outcome measure was pain relief with short-term relief defined as up to 6 months and long-term relief as 12 months. Secondary outcome measures were improvement in functional status, psychological status, return to work, and reduction in opioid intake. Results: For this systematic review, 122 studies were identified. Of these, 11 randomized trials and 14 observational studies met inclusion criteria for methodological quality assessment. The evidence for radiofrequency neurotomy is good and fair to good for lumbar facet joint nerve blocks for short- and long-term improvement; whereas the evidence for intraarticular injections and pulsed radiofrequency neurotomy is limited. Limitations: The limitations of this systematic review include the continued paucity of evidence, specifically for intraarticular injection therapy. Conclusion: In summary, there is good evidence for the use of conventional radiofrequency neurotomy, and fair to good evidence for lumbar facet joint nerve blocks for the treatment of chronic lumbar facet joint pain resulting in short-term and long-term pain relief and functional improvement. There is limited evidence for intraarticular facet joint injections and pulsed radiofrequency thermoneurolysis. Key Words: Spinal pain, chronic low back pain, lumbar intraarticular facet joint blocks, lumbar facet joint nerve blocks, lumbar conventional radiofrequency neurotomy, pulsed radiofrequency neurolysis
