Right Lower Extremity Pain With Full Bladder--pilates/dance

Background: Intervertebral disc herniation, spinal stenosis, intervertebral disc degeneration without disc herniation, and post lumbar surgery syndrome are the most common diagnoses of chronic persistent low back and lower extremity symptoms, resulting in significant economic, societal, and health care impact. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back pain. However the evidence is highly variable among different techniques utilized – namely interlaminar, caudal, and transforaminal – and for various conditions, namely – intervertebral disc herniation, spinal stenosis, and discogenic pain without disc herniation or radiculitis. Multiple systematic reviews conducted in the evaluation of the effectiveness of interlaminar epidural injections have been marred with controversy. Consequently, the debate continues with regards to the effectiveness, indications, and medical necessity of interlaminar epidural injections. Study Design: A systematic review of lumbar interlaminar epidural injections with or without steroids. Objective: To evaluate the effect of lumbar interlaminar epidural injections with or without steroids in managing various types of chronic low back and lower extremity pain emanating as a result of disc herniation or radiculitis, spinal stenosis, and chronic discogenic pain. Methods: The available literature on lumbar interlaminar epidural injections with or without steroids in managing various types of chronic low back pain with or without lower extremity 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, or limited 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 December 2011, 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: Overall, 82 lumbar interlaminar trials were identified. All non-randomized studies without fluoroscopy and randomized trials not meeting the inclusion criteria were excluded. Overall, 15 randomized trials and 11 non-randomized studies were included in the analysis. Analysis was derived mainly from fluoroscopically-guided randomized trials and non-randomized studies. The evidence is good for radiculitis secondary to disc herniation with local anesthetics and steroids, fair with local anesthetic only; whereas it is fair for radiculitis secondary to spinal stenosis with local anesthetic and steroids, and fair for axial pain without disc herniation with local anesthetic with or without steroids, with fluoroscopically-guided epidural injections. Limitations: The limitations of this study include that we were unable to perform meta-analysis for disc herniation, and the paucity of evidence for discogenic pain and spinal stenosis. Further, methodological criteria have been highly variable along with sample sizes. The studies were heterogenous. Conclusion: The evidence based on this systematic review is good for lumbar epidural injections under fluoroscopy for radiculitis secondary to disc herniation with local anesthetic and steroids, fair with local anesthetic only; whereas it is fair for radiculitis secondary to spinal stenosis with local anesthetic and steroids, and fair for axial pain without disc herniation with local anesthetic with or without steroids. Key words: Chronic low back pain, lower extremity pain, disc herniation, radiculitis, spinal stenosis, discogenic pain, lumbar interlaminar epidural injections, fluoroscopy

Team Evaluation

Patients with persistent complex limb pain represent a substantial diagnostic challenge. Physical exam, and tests such as nerve conduction, are often normal even though the patient suffers from severe pain. In 2015, we initiated a team-based approach to evaluate such patients. The approach included physicians from several specialties (Anesthesiology/Pain Medicine, Radiology, Plastic Surgery, Neurosurgery) combined with the use of advanced imaging with Magnetic Resonance Neurography (MRN). This preliminary case series discusses MRN findings identified in patients with previously difficult-to-diagnose peripheral limb pain and describes how this combination of approaches influenced our diagnosis and treatment plans. We extracted demographics, patient characteristics, presenting features, diagnostic tests performed, treatments provided, referral diagnosis and the diagnosis after interdisciplinary team evaluation from patient charts. We evaluated MRN and electrodiagnostic studies (EDX) ability to identify injured nerves. We compared abnormal findings from these diagnostics to patient reported outcome after ultrasound-guided nerve block. A total of 58 patients, 17 males and 41 females, were identified. The majority of patients presented with lower extremity pain (75%) and had prior surgery (43%). The most commonly identified abnormality on MRN was nerve signal alteration on fluid sensitive sequences, followed by caliber change and impingement. Comparing the outcome of diagnostic nerve blocks with abnormal nerve findings on MRN or EDX, we found that MRN had a sensitivity of 67% and specificity of 100% while for EDX it was 45 and 0%, respectively. After interdisciplinary discussion and imaging review, a more specific diagnosis was produced in 78% of evaluated cases opening up additional treatment pathways such as nerve-targeted surgery, which was performed in 36% cases. This descriptive case series demonstrates that a majority of patients evaluated by our team for complex limb pain were women with lower extremity pain resulting from surgery. In addition, an interdisciplinary team evaluation and the use of the moderately sensitive but highly specific MRN imaging modality resulted in a change in diagnosis for a majority of patients with complex limb pain. Future studies investigating patient outcomes after diagnosis change are currently underway based on the findings of this preliminary study.

Lower Extremity Pain

Background: Low back pain with or without lower extremity pain is the most common problem among chronic pain disorders with significant economic, societal, and health impact. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back pain. However the evidence is highly variable among different techniques utilized – namely interlaminar, caudal, transforaminal – and for various conditions, namely – intervertebral disc herniation, spinal stenosis, and discogenic pain without disc herniation or radiculitis. Study Design: A systematic review of lumbar interlaminar epidural injections with or without steroids. Objective: To evaluate the effect of lumbar interlaminar epidural injections with or without steroids in managing various types of chronic low back and lower extremity pain emanating as a result of disc herniation or radiculitis, spinal stenosis, and chronic discogenic pain. Methods: Review of the literature and methodologic quality assessment were performed according to the Cochrane Musculoskeletal Review Group Criteria as utilized for interventional techniques for randomized trials and the Agency for Healthcare Research and Quality (AHRQ) criteria for observational studies. The level of evidence was classified as Level I, II, or III based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF) for therapeutic interventions. Data sources included relevant literature of the English language identified through searches of PubMed and EMBASE from 1966 to November 2008, and manual searches of bibliographies of known primary and review articles. Results of analysis were performed for multiple conditions separately. 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: The available literature included only blind epidural injections without fluoroscopy. The indicated evidence is positive (Level II-2) for short-term relief of pain of disc herniation or radiculitis utilizing blind interlaminar epidural steroid injections with lacking of evidence with Level III for long-term relief for disc herniation and radiculitis. The evidence is lacking with Level III for short and long-term relief for spinal stenosis and discogenic pain without radiculitis or disc herniation utilizing blind epidural injections. Limitations: The limitations of this study include paucity of literature, lack of quality evidence, lack of fluoroscopic procedures, and lack of applicable evidence in contemporary interventional pain management practices. Conclusion: The evidence based on this systematic review is limited for blind interlaminar epidurals in managing all types of pain except for short-term relief of pain secondary to disc herniation and radiculitis. This evidence does not represent contemporary interventional pain management practices and also the evidence may not be extrapolated to fluoroscopically directed lumbar interlaminar epidural injections.
