Object The authors assessed the effectiveness of percutaneous pulsed radiofrequency treatment for providing pain relief in patients with chronic low-back pain with or without lower-limb pain. Methods Data were obtained in 127 patients who had chronic low-back pain with or without lower-limb pain due to a herniated intervertebral disc or previous failed back surgery and who underwent pulsed radiofrequency treatment. Their conditions were proven by clinical features, physical examination, and imaging studies. Low-back pain was treated with pulsed radiofrequency applied to the L-2 dorsal root ganglion (DRG) and lower-limb pain was treated with pulsed radiofrequency applied to the L3–S1 DRG. Patients underwent uni- or bilateral treatment depending on whether their low-back pain was unilateral or bilateral. A visual analog scale was used to assess pain. The patients were followed up for 3 years postoperatively. Results In patients without lower-limb pain (Group A), 27 (55.10%) of 49 patients had initial improvement ≥ 50% at 3-month follow-up. At 1-year follow-up, 20 (44.44%) of 45 patients in Group A had pain relief ≥ 50%. An analysis of patients with pain relief ≥ 50% for at least 1 month showed that the greatest effect was at 3 months after treatment. In patients with low-back pain and lower-limb pain (Group B), 37 (47.44%) of 78 patients had initial improvement ≥ 50% at 3-month follow-up. At 1-year follow-up, 34 (45.95%) of 74 patients had pain relief effect ≥ 50%. An analysis of patients in Group B with pain relief ≥ 50% for at least 1 month showed that the greatest effect was at 1 month after treatment. Conclusions The results of this prospective analysis showed that treatment with pulsed radiofrequency applied at the L-2 DRG is safe and effective for treating for chronic low-back pain. Satisfactory pain relief was obtained in the majority of patients in Group A with the effect persisting for at least 3 months. The results indicate that pulsed radiofrequency provided intermediate-term relief of low-back pain. Further studies with long-term follow-up are necessary.

Background: Epidural injections (EI) are the most commonly performed minimally invasive intervention to manage chronic low back pain (CLBP) with lumbosacral radicular pain (LRP). Local anesthetic (LA) and/ or steroids are frequently used injectates for EI and are reported with variable effectiveness. The majority of earlier studies have used either caudal, transforaminal (TF), or undefined interlaminar approaches for EI. The parasaggital interlaminar (PIL) approach route is reported to have good ventral epidural spread and comparable effectiveness to the TF route. However, there is a lack of head-to-head comparative effectiveness research of LA with or without steroid for managing CLBP with LRP using a PIL approach. Objective: To compare the effectiveness of EI of LA alone and LA with steroid using a PIL approach for managing CLBP with LRP. Study Design: Randomized, double blind, active control one year follow-up study. Setting: Interventional pain management clinic in a tertiary care center in India. Methods: Sixty-nine patients were randomized to receive fluoroscopic guided EI of either 8 mL of 0.5% lidocaine (group L, n = 34) or 6 mL of 0.5% lidocaine mixed with 80 mg (2 mL) of methylprednisolone acetate (group LS, n = 35). Patients were evaluated for pain intensity using 0 – 10 numerical rating scale (NRS) and functional disability using Modified Oswestry Disability Questionnaire (MODQ) at baseline; and 2 weeks, one, 2, 3, 6, 9, and 12 months after injection. Patients with inefficacy with the initial injection or response deterioration received an additional injection of the same injectate and dose. Patients were evaluated for achieving effective pain relief (EPR, i.e., ≥ 50% from baseline), overall NRS and MODQ, number of injections, and presence of ventral and perineural spread over one year follow-up. Primary outcome was proportion of patients achieving EPR at 3 months. Results: A significantly higher proportion of patients achieved EPR at 3 months in group LS [30 (86%, 90% CI 73% – 93%)] as compared to group L [17 (50%, 90% CI 36% – 64%)] (P = 0.02). Similar results were obtained at 6, 9, and 12 months, respectively. The probability of achieving EPR was significantly higher in group LS at various time-points during the one year follow-up as compared to group L (P = 0.01) A significant reduction in NRS and improvement in MODQ were observed at all time-points post-intervention compared to baseline (P < 0.001) in both groups. NRS and MODQ scores were significantly lower in group LS as compared to group L at all time intervals post baseline. On average patients in group L received 2.0 (0.85) and group LS received 1.7 (0.71) injections annually (P = 0.07). Ventral epidural spread was comparable in both groups (97%). No major complications were encountered in either group; however, intravascular spread of contrast was noted during 2 injections (one in each group) requiring relocation. Limitations: A single center study, lack of documentation of adjuvant therapies like individual analgesic medication, and lack of placebo group. Conclusions: Using a PIL approach and the addition of steroid to LA for EI may provide superior effectiveness in terms of extent and duration of pain relief for managing CLBP with unilateral LRP, even though, local anesthetic alone also was effective.

Many treatment options for chronic low back pain are available, including varied forms of electric stimulation. But little is known about the electricity effect between electro-acupuncture and pulsed radiofrequency. The objective of this study is to assess the difference in effectiveness of pain relief between pulsed radiofrequency and electro-acupuncture. Visual analog score (VAS) pain score, the Oswestry disability index (ODI) to measure a patient's permanent functional disability, and Short form 36 (SF-36) which is a survey used in health assessment to determine the cost-effectiveness of a health treatment, were used as rating systems to measure the pain relief and functional improvement effect of pulsed radiofrequency and electro-acupuncture, based on the methodological quality of the randomized controlled trials, the relevance between the study groups, and the consistency of the outcome evaluation. First, the baseline status before therapy shows no age and gender influence in the SF-36 and VAS score but it is significant in the ODI questionnaire. From ANOVA analyses, it is apparent that radiofrequency therapy is a significant improvement over electro-acupuncture therapy after one month. But electro-acupuncture also showed functional improvement in the lumbar spine from the ODI. This study provides sufficient evidence of the superiority of pulsed radiofrequency (PRF) therapy for low back pain relief compared with both electro-acupuncture (EA) therapy and the control group. But the functional improvement of the lumbar spine was proved under EA therapy only. Both therapies are related to electricity effects.

The Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) was created to evaluate specific treatment outcomes in terms of physical functioning, social ability, and mental health in patients with back pain-related diseases. In this study, we investigated whether the JOABPEQ could be used to construct a regression model to quantify low back pain and lower limb symptoms in patients with lumbar disc herniation (LDH). We reviewed 114 patients with LDH scheduled to undergo surgery at our hospital. We measured the degrees of 1) lower back pain, 2) lower limb pain, and 3) lower limb numbness using the visual analog scale before the surgery. All answers and physical function data were subjected to partial least squares regression analysis. The degrees of lower back and lower limb pain could be used as a regression model from the JOABPEQ and had a significant causal relationship with them. However, the degree of lower limb numbness could not be used for the same. Based on our results, the questions of the JOABPEQ can be used to multilaterally understand the degree of lower back pain and lower limb pain in patients with LDH. However, the degree of lower limb numbness has no causal relationship, so actual measurement is essential.

AbstractSince pseudoarthrosis or screw loosening is frequently seen in lumbosacral stabilizations ending in S1, S2 screws are used more frequently to support S1 screws. This study aims to describe a new screw placement technique and location from S2. Revision surgery was applied to the patient who had previously undergone surgery with the rigid instrumentation system and encountered pseudoarthrosis during the follow-up period. Instrumentation was performed from S2 to the promontorium. The patient’s chronic low back pain arising due to pseudoarthrosis was reduced and a strong lumbosacral dynamic instrumentation was performed to the patient. Dual screw placement from S2 and/or screw placement in the S2-promontorium direction is a new alternative to provide a powerful instrumentation.

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.

Abstract Background: Chronic low back pain (cLBP) is a major health problem and the most common pain condition among those 60 years of age or older in the US. Despite the development of pharmacological and nonpharmacological interventions, cLBP outcomes have not improved and disability rates continue to rise. This study aims to test auricular point acupressure (APA) as a non-invasive, nonpharmacological self-management strategy to manage cLBP and to address current shortcomings of cLBP treatment. Methods: For this prospective randomized controlled study, participants will be randomly assigned into three groups: (1) APA (active points related to cLBP), (2) Comparison Group -1 (non-active points, unrelated to cLBP), (3) Comparison Group-2 (enhanced educational control, an educational booklet on cLBP will be given and the treatment used by participants for their cLBP will be recorded). The ecological momentary assessment smartphone app will be used to collect real-time cLBP outcomes and adherence to APA practice. Treatment and nonspecific psychological placebo effects will be measured via questionnaires for all participants. This proposed trial will evaluate the APA sustained effects for cLBP at 12-month follow-up. Monthly phone follow-up will be used to collect study outcomes. Blood will be collected during study visits at baseline, post-APA treatment, and follow-up study visits at 1-, 3-, 6-, 9- and 12-months post-completion of treatment for a total of 7 assessments. Appointments will start between 9 and 11 am to control for circadian variation in cytokine levels. Discussion: This study is expected to provide vital information on the efficacy, sustainability, and underlying mechanism of APA on cLBP necessary for APA to gain acceptance from both healthcare providers and patients, which would provide a strong impetus for including APA as part of cLBP management in clinical and home settings.
