Background: Chronic mid back and upper back pain caused by thoracic facet joints has been reported in 34% to 48% of patients based on responses to controlled diagnostic blocks. Systematic reviews have established moderate evidence for controlled comparative local anesthetic blocks of thoracic facet joints in the diagnosis of mid back and upper back pain, moderate evidence for therapeutic thoracic medial branch blocks, and limited evidence for radiofrequency neurotomy of thoracic medial branches. Study Design: Systematic review of therapeutic thoracic facet joint interventions. Objective: To determine the clinical utility of therapeutic thoracic facet joint interventions in the therapeutic management of chronic upper back and mid back pain. Methods: The available literature for the utility of facet joint interventions in the therapeutic management of thoracic facet joint 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. Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to March 2012, and manual searches of the bibliographies of known primary and review articles. Outcome Measures: The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status, psychological status, return to work, and reduction in opioid intake. Results: For this systematic review, 13 studies were identified. Of these, 7 studies were excluded, and a total of 4 studies (after removal of duplicate publication) met inclusion criteria for methodological quality assessment with one randomized trial and 3 non-randomized studies. The evidence is fair for therapeutic thoracic facet joint nerve blocks, limited for thoracic radiofrequency neurotomy, and not available for thoracic intraarticular injections. Limitations: The limitation of this systematic review includes a paucity of literature. The only positive studies were of medial branch blocks performed by the same group of authors. Conclusion: The evidence for therapeutic facet joint interventions is fair for medial branch blocks, whereas it is not available for intraarticular injections, and limited for radiofrequency neurotomy due to lack of literature. Key words: Chronic thoracic pain, mid back or upper back pain, thoracic facet or zygapophysial joint pain, facet joint nerve blocks, medial branch blocks, therapeutic thoracic medial branch blocks, thoracic radiofrequency neurotomy, thoracic intraarticular facet joint injections

Background: The prevalence of chronic, recurrent neck pain is approximately 15% of the adult general population. Controlled studies have supported the existence of cervical facet or zygapophysial joint pain in 36% to 67% of these patients, when disc herniation, radiculitis, and discogenic are not pathognomic. However, these studies also have shown false-positive results in 27% to 63% of the patients with a single diagnostic block. There is also a paucity of literature investigating therapeutic interventions of cervical facet joint pain. Study Design: Systematic review of therapeutic cervical facet joint interventions. Objective: To determine and update the clinical utility of therapeutic cervical facet joint interventions in the management of chronic neck pain. Methods: The available literature for utility of facet joint interventions in therapeutic management of cervical facet joint 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. 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: The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status, psychological status, return to work, and reduction in opioid intake. Results: In this systematic review, 32 manuscripts were considered for inclusion. For final analysis, 4 randomized trials and 6 observational studies met the inclusion criteria and were included in the evidence synthesis. Based on one randomized, sham-controlled, double-blind trial and 5 observational studies, the indicated evidence for cervical radiofrequency neurotomy is fair. Based on one randomized, double-blind, active-controlled trial and one prospective evaluation, the indicated evidence for cervical medial branch blocks is fair. Based on 2 randomized controlled trials, the evidence for cervical intraarticular injections is limited. Limitations: Paucity of the overall published literature and specifically lack of literature for intraarticular cervical facet joint injections. Conclusions: The indicated evidence for cervical radiofrequency neurotomy is fair. The indicated evidence for cervical medial branch blocks is fair. The indicated evidence for cervical intraarticular injections with local anesthetic and steroids is limited.

Background: Chronic mid back and upper back pain caused by thoracic facet joints has been reported in 34% to 48% of the patients based on their responses to controlled diagnostic blocks. Systematic reviews have established moderate evidence for controlled comparative local anesthetic blocks of thoracic facet joints in the diagnosis of mid back and upper back pain. Objective: To determine the diagnostic accuracy of thoracic facet joint nerve blocks in the assessment of chronic upper back and mid back pain. Study Design: Systematic review of the diagnostic accuracy of thoracic facet joint nerve blocks. 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 critically analyzed. 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 March 2012, and manual searches of the bibliographies of known primary and review articles. Outcome Measures: Controlled placebo or local anesthetic blocks were utilized using at least 50% pain relief as the reference standard. Results: Three studies were identified utilizing controlled comparative local anesthetic blocks, with ≥50% pain relief as the criterion standard. The evidence is good for the diagnosis of thoracic pain of facet joint origin with controlled diagnostic blocks. Limitations: The limitations of this systematic review include a paucity of literature for the diagnosis of thoracic facet joint pain, with all included manuscripts originating from one group of authors. Conclusions: Based on this systematic review, the evidence for the diagnostic accuracy of thoracic facet joint injections is good.

Background: Chronic, recurrent neck pain is common and is associated with high pain intensity and disability, which is seen in 14% of the adult general population. Controlled studies have supported the existence of cervical facet or zygapophysial joint pain in 36% to 67% of these patients. However, these studies also have shown false-positive results in 27% to 63% of the patients with a single diagnostic block. There is also a paucity of literature investigating therapeutic interventions of cervical facet joint pain. Study Design: A systematic review of cervical facet joint interventions. Objective: To evaluate the accuracy of diagnostic facet joint nerve blocks and the effectiveness of cervical facet joint interventions. Methods: Medical databases and journals were searched to locate all relevant literature from 1966 through December 2008 in the English language. A review of the literature of the utility of facet joint interventions in diagnosing and managing facet joint pain was performed according to the Agency for Healthcare Research and Quality (AHRQ) criteria for diagnostic studies and observational studies and the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials. Level of Evidence: The level of evidence was defined as Level I, II, or III based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF). Outcome Measures: For diagnostic interventions, studies must have been performed utilizing controlled local anesthetic blocks which achieve at minimum 80% relief of pain and the ability to perform previously painful movements. For therapeutic interventions, the primary outcome measure was pain relief (short-term relief up to 6 months and long-term relief greater than 6 months) with secondary outcome measures of improvement in functional status, psychological status, return to work, and reduction in opioid intake. Results: Based on the utilization of controlled comparative local anesthetic blocks, the evidence for the diagnosis of cervical facet joint pain is Level I or II-1. The indicated evidence for therapeutic cervical medial branch blocks is Level II-1. The indicated evidence for radiofrequency neurotomy in the cervical spine is Level II-1 or II-2, whereas the evidence is lacking for intraarticular injections. Limitations: A systematic review of cervical facet joint interventions is hindered by the paucity of published literature and lack of literature for intraarticular cervical facet joint injections. Conclusions: The evidence for diagnosis of cervical facet joint pain with controlled comparative local anesthetic blocks is Level I or II-1. The indicated evidence for therapeutic facet joint interventions is Level II-1 for medial branch blocks, and Level II-1 or II-2 for radiofrequency neurotomy. Key words: Chronic neck pain, cervical facet or zygapophysial joint pain, cervical medial branch blocks, controlled comparative local anesthetic blocks, cervical radiofrequency neurotomy, cervical intraarticular facet joint injections

Chronic Spinal Pain

Background: The therapeutic spinal facet joint interventions generally used for the treatment of axial spinal pain of facet joint origin are intraarticular facet joint injections, facet joint nerve blocks, and radiofrequency neurotomy. Despite interventional procedures being common as treatment strategies for facet joint pathology, there is a paucity of literature investigating these therapeutic approaches. Systematic reviews assessing the effectiveness of various therapeutic facet joint interventions have shown there to be variable evidence based on the region and the modality of treatment utilized. Overall, the evidence ranges from limited to moderate. Objective: To evaluate and update the clinical utility of therapeutic lumbar, cervical, and thoracic facet joint interventions in managing chronic spinal pain. Study Design: A systematic review of therapeutic lumbar, cervical, and thoracic facet joint interventions for the treatment of chronic spinal pain. Methods: The available literature on lumbar, cervical, and thoracic facet joint interventions in managing chronic spinal pain was reviewed. The quality assessment criteria utilized were the Cochrane Musculoskeletal Review Group criteria and Interventional Pain Management Techniques – Quality Appraisal of Reliability and Risk of Bias Assessment (IPM – QRB) for randomized trials and Interventional Pain Management Techniques – Quality Appraisal of Reliability and Risk of Bias Assessment for Nonrandomized Studies (IPM – QRBNR) for observational studies. The level of evidence was classified at 5 levels from Level I to Level V. Data sources included relevant literature identified through searches on PubMed and EMBASE from 1966 through March 2015, and manual searches of the bibliographies of known primary and review articles. Outcome Measures: The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status, psychological status, return to work, and reduction in opioid intake consumption. Results: A total of 21 randomized controlled trials meeting appropriate inclusion criteria were assessed in this evaluation. A total of 5 observational studies were assessed. In the lumbar spine, for long-term effectiveness, there is Level II evidence for radiofrequency neurotomy and lumbar facet joint nerve blocks, whereas the evidence is Level III for lumbosacral intraarticular injections. In the cervical spine, for long-term improvement, there is Level II evidence for cervical radiofrequency neurotomy and cervical facet joint nerve blocks, and Level IV evidence for cervical intraarticular injections. In the thoracic spine there is Level II evidence for thoracic facet joint nerve blocks and Level IV evidence for radiofrequency neurotomy for long-term improvement. Limitations: The limitations of this systematic review include an overall paucity of high quality studies and more specifically the lack of investigations related to thoracic facet joint injections. Conclusion: Based on the present assessment for the management of spinal facet joint pain, the evidence for long-term improvement is Level II for lumbar and cervical radiofrequency neurotomy, and therapeutic facet joint nerve blocks in the cervical, thoracic, and lumbar spine; Level III for lumbar intraarticular injections; and Level IV for cervical intraarticular injections and thoracic radiofrequency neurotomy.

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.

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 have shown the prevalence of lumbar facet joint pain in 27% to 40% of the patients with chronic low back pain without disc displacement or radiculitis, with a false-positive rate of 27% to 47% with a single diagnostic block. Study Design: A systematic review of diagnostic and therapeutic lumbar facet joint interventions. Objective: To determine the clinical utility of diagnostic and therapeutic lumbar facet joint interventions in managing chronic low back pain of facet joint origin. Methods: Review of the literature for clinical studies on efficacy and utility of facet joint interventions in diagnosing and managing facet joint pain was performed according to the Agency for Healthcare Research and Quality (AHRQ) criteria for diagnostic studies and observational studies and the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials. Data sources included relevant literature of the English language identified through searches of Medline and EMBASE from 1966 to December 2008 and manual searches of bibliographies of known primary and review articles. Analysis results were performed for diagnostic and therapeutic interventions separately. Level of Evidence: The level of evidence was defined as Level I, II, or III with 3 subcategories in Level II based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF) for therapeutic interventions. Outcome Measures: For diagnostic interventions, studies must have been performed utilizing controlled local anesthetic blocks. Pain relief was categorized as at least 80% pain relief from baseline pain and ability to perform previously painful movements. For therapeutic interventions, the primary outcome measure was pain relief with secondary outcome measures of improvement in functional status, psychological status, return to work, and reduction in opioid intake. For therapeutic interventions, short-term pain relief was defined as relief lasting 6 months or less and long-term relief as longer than 6 months. Results: Based on USPSTF criteria, evidence showed Level I or II-1 for diagnostic facet joint nerve blocks. Based on the review of included therapeutic studies, Level II-1 to II-2 evidence was indicated for lumbar facet joint nerve blocks with indicated level of evidence of Level II-2 to II-3 for lumbar radiofrequency neurotomy. Limitations: The shortcoming of this systematic review of lumbar facet joint interventions is the paucity of published literature. Conclusion: The evidence for diagnosis of lumbar facet joint pain with controlled local anesthetic blocks is Level I or II-1. The indicated level of evidence for therapeutic lumbar facet joint interventions is Level II1 or II-2 for lumbar facet joint nerve blocks, Level II-2 or II-3 evidence for radiofrequency neurotomy, and Level III (limited) evidence for intraarticular injections.

Background: A 2-year review of literature from October 2004 to December 2006 was completed to update current scientific evidence on diagnostic utility of facet joint injections. Diagnostic injections are employed to diagnose facet joint pain because available techniques cannot identify the pain generating structure in patients with chronic spinal pain. There is no physical examination technique, laboratory test, or imaging modality that can precisely identify the spinal structure causing pain, distinguish the culprit from a variety of potential targets, and predict response to a therapeutic intervention. Zygapophysial joint injections, commonly called facet injections (intra-articular joint injections and medial branch blocks) are local anesthetic injections of the facet joint or its nerve supply. These are diagnostic procedures used to determine if pain is arising from facet joints, distinguish painful from nonpainful joints and prognosticate response to therapeutic facet joint interventions. Diagnostic injections must meet the cardinal features of a diagnostic test i.e., accuracy, safety, and reproducibility. Accuracy is based on comparison with a “gold standard” to confirm presence or absence of a disease. There is, however, no available gold standard to measure presence or absence of pain. Hence, there is a degree of uncertainty concerning the accuracy of diagnostic facet joint injections. Objectives: Evaluate and update available evidence (2004 to 2006) relating to clinical utility of facet joint injections (intraarticular and medial branch blocks) in diagnosing chronic spinal pain of facet joint origin. Study Design: Review of the literature for clinical studies on efficacy and utility of facet joint/nerve injections in diagnosing facet joint pain according to Agency for Healthcare Research and Quality (AHRQ) and Quality Assessment Studies of Diagnostic Accuracy (QUADAS) criteria. The level of evidence was classified as conclusive (Level I), strong (Level II), moderate (Level III), or limited (Level IV). Methods: Computerized database search (2004 to 2006) of PUBMED, EMBASE, CINAHL, and Web of Knowledge was conducted to identify studies on facet joint pain and diagnostic interventions. Abstracts, reviews, book chapters, case reports, studies based on single blocks or blocks without radiologic control, and studies describing techniques were excluded. Prospective studies were given priority over retrospective studies. Results: There is no change in the strength of evidence for facet joint diagnostic injections. There is strong evidence for controlled comparative local anesthetic facet joint injections or medial branch blocks in the diagnosis of neck and low back pain and moderate evidence in the diagnosis of pain arising from thoracic facet joints. Conclusion: The evidence obtained from literature review suggests that controlled comparative local anesthetic blocks of facet joints (medial branch or dorsal ramus) are reproducible, reasonably accurate and safe. The sensitivity, specificity, false-positive rates, and predictive values of these diagnostic tests for neck and low back pain have been validated and reproduced in multiple studies.

We report 2 cases of successful treatment of neck and back pain with bipolar radiofrequency ablation (RFA) of the cervical and lumbar facet joints in patients with an automatic implantable cardioverter defibrillator (AICD). Two patients with complex cardiac histories and AICD devices were treated with bipolar RFA of the facet joints. One presented with axial neck pain and the other with axial back pain. The histories and physical examinations were consistent with facetogenic pain. Diagnostic medial branch block resulted in more than 70% pain relief lasting for several days, allowing patients to perform routine daily activities without significant pain. However, we were concerned about the use of conventional RFA of the medial branches of nerves for the fear of interference with the function of AICD by the RF currents and energy. We took advantage of the localized and limited current of bipolar RFA to perform this procedure for the cervical or lumbar facet joints avoiding any interference with the function of AICD. The procedures provided long-term pain relief to the patients, and marked improvement in their functional status without any evident complications related to the function of their AICD. This case report describes the safe and successful completion of bipolar RFA of the medial branch nerves to treat cervical and lumbar facetogenic pain in patients with AICD. This modality of treatment may be considered in patients with AICD. We are finding it to be increasingly common that patients who present with chronic neck and back pain have AICDs in place.

Background: The prevalence of implantable electronic devices, particularly deep brain stimulators (DBS), is increasing worldwide. To date, there has been limited research on the safety of radiofrequency neurotomy for lumbar facet joint pain in patients with implanted DBS. Furthermore, there are no clear guidelines on the management of DBS prior to radiofreqeuency neurotomy. Case Report: We present the case of a patient with Parkinson’s disease status post implantation of DBS for management of symptoms. Appropriate safety precautions were taken prior to and following the treatment procedure for the patient. Prior to the procedure, consultation with a device technical representative took place and the patient’s device was switched to “surgery mode.” This patient then underwent bipolar radiofrequency denervation of the bilateral lumbar medial branches with significant improvement in her pain and without any adverse effects upon postprocedure exam. Conclusion: We propose several steps and precautions when employing radiofrequency denervation in a patient with history of prior DBS implantation. By taking these precautions, radiofrequency denervation can safely be used in patients with DBS for the management of lower back pain.
