Objective: To develop evidence-based clinical practice guidelines for interventional techniquesin the diagnosis and treatment of chronic spinal pain.Methodology: Systematic assessment of the literature.Evidence:I. Lumbar Spine• The evidence for accuracy of diagnostic selective nerve root blocks is limited;whereas for lumbar provocation discography, it is fair.• The evidence for diagnostic lumbar facet joint nerve blocks and diagnosticsacroiliac intraarticular injections is good with 75% to 100% pain relief as criterionstandard with controlled local anesthetic or placebo blocks.• The evidence is good in managing disc herniation or radiculitis for caudal, interlaminar,and transforaminal epidural injections; fair for axial or discogenic pain withoutdisc herniation, radiculitis or facet joint pain with caudal, and interlaminar epiduralinjections, and limited for transforaminal epidural injections; fair for spinalstenosis with caudal, interlaminar, and transforaminal epidural injections;and fair for post surgery syndrome with caudal epidural injections and limited withtransforaminal epidural injections.• The evidence for therapeutic facet joint interventions is good for conventionalradiofrequency, limited for pulsed radiofrequency, fair to good for lumbar facetjoint nerve blocks, and limited for intraarticular injections.• For sacroiliac joint interventions, the evidence for cooled radiofrequency neurotomyis fair; limited for intraarticular injections and periarticular injections; and limitedfor both pulsed radiofrequency and conventional radiofrequency neurotomy.• For lumbar percutaneous adhesiolysis, the evidence is fair in managing chronic lowback and lower extremity pain secondary to post surgery syndrome and spinal stenosis.• For intradiscal procedures, the evidence for intradiscal electrothermal therapy(IDET) and biaculoplasty is limited to fair and is limited for discTRODE.• For percutaneous disc decompression, the evidence is limited for automatedpercutaneous lumbar discectomy (APLD), percutaneous lumbar laser disc decompression, and Dekompressor; and limited to fair for nucleoplasty for which the Centers for Medicareand Medicaid Services (CMS) has issued a noncoverage decision.II. Cervical Spine• The evidence for cervical provocation discography is limited; whereas the evidence for diagnostic cervicalfacet joint nerve blocks is good with a criterion standard of 75% or greater relief with controlled diagnosticblocks.• The evidence is good for cervical interlaminar epidural injections for cervical disc herniation or radiculitis;fair for axial or discogenic pain, spinal stenosis, and post cervical surgery syndrome.• The evidence for therapeutic cervical facet joint interventions is fair for conventional cervical radiofrequencyneurotomy and cervical medial branch blocks, and limited for cervical intraarticular injections.III. Thoracic Spine• The evidence is limited for thoracic provocation discography and is good for diagnostic accuracy of thoracicfacet joint nerve blocks with a criterion standard of at least 75% pain relief with controlled diagnostic blocks.• The evidence is fair for thoracic epidural injections in managing thoracic pain.• The evidence for therapeutic thoracic facet joint nerve blocks is fair, limited for radiofrequencyneurotomy, and not available for thoracic intraarticular injections.IV. Implantables• The evidence is fair for spinal cord stimulation (SCS) in managing patients with failed back surgery syndrome(FBSS) and limited for implantable intrathecal drug administration systems.V. Anticoagulation• There is good evidence for risk of thromboembolic phenomenon in patients with antithrombotic therapyif discontinued, spontaneous epidural hematomas with or without traumatic injury in patients with or withoutanticoagulant therapy to discontinue or normalize INR with warfarin therapy, and the lack of necessity ofdiscontinuation of nonsteroidal anti-inflammatory drugs (NSAIDs), including low dose aspirin prior to performinginterventional techniques.• There is fair evidence with excessive bleeding, including epidural hematoma formation with interventional techniqueswhen antithrombotic therapy is continued, the risk of higher thromboembolic phenomenon than epiduralhematomas with discontinuation of antiplatelet therapy prior to interventional techniques and to continuephosphodiesterase inhibitors (dipyridamole, cilostazol, and Aggrenox).• There is limited evidence to discontinue antiplatelet therapy with platelet aggregation inhibitors toavoid bleeding and epidural hematomas and/or to continue antiplatelet therapy (clopidogrel, ticlopidine, prasugrel)during interventional techniques to avoid cerebrovascular and cardiovascular thromboembolic fatalities.• There islimited evidence in reference to newer antithrombotic agents dabigatran (Pradaxa) and rivaroxan(Xarelto) to discontinue to avoid bleeding and epidural hematomas and are continued during interventionaltechniques to avoid cerebrovascular and cardiovascular thromboembolic events.Conclusion: Evidence is fair to good for 62% of diagnostic and 52% of therapeutic interventions assessed.Disclaimer: The authors are solely responsible for the content of this article.
