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.

BACKGROUND: Chronic low back pain (CLBP) is an extremely prevalent disease, whose etiology is often multifactorial. Facet joint arthropathy is one of the most common causes of CLBP. Facet joints are innervated by the medial branches of the primary and adjacent level dorsal rami and are, therefore, key potential targets for the symptomatic management of CLBP. A lumbar medial branch nerve block (MBB) procedure is often used to assist in the diagnosis of facet mediated CLBP. For unclear reasons, some patients experience protracted relief of CLBP after diagnostic MBBs alone. OBJECTIVE: To describe the phenomenon of protracted relief of CLBP after diagnostic MBBs and search for predictors of this response. STUDY DESIGN: A retrospective chart review of patients who underwent MBB procedures by a single practitioner, over a 2 year period, was conducted. SETTING: All patients were seen at the Montefiore Multidisciplinary Pain Program, Bronx, NY. METHODS: Data from follow up visits was used to categorize patient’s response to MBBs as having no relief (NR), transient relief (TR) or protracted relief (PR). Patient demographics and characteristics were collected, and a multivariate analysis investigating associations with PR was conducted. RESULTS: 146 patients met inclusion criteria. 41 patients (28%) had NR, 54 (37%) had TR, and 51 (35%) had PR. CLBP symptom duration of < 6 months (P = 0.013) and unilateral back pain symptoms (P = 0.0253) were significantly associated with PR after MBB. LIMITATION: This is a retrospective study with a relatively small sample size conducted on patients belonging to a single practitioner. Outcomes were based largely on subjective patient satisfaction scores. CONCLUSIONS: In select patients, MBB may produce protracted relief of CLBP symptoms. The authors present distinct hypotheses which may help explain the therapeutic effects of diagnostic MBB procedures. KEY WORDS: Chronic low back pain, facet joint, medial branch nerve block

Study design: Cross-sectional study. Background: Neuromuscular electrical stimulation (NMES) is an effective tool for stimulating multifidus muscle contractions. Ultrasound imaging (USI) is valid and reliable for quantifying multifidus activity represented by percent thickness change from a resting to contracted state. Thus, USI may be used to help determine optimal NMES intensity. Objectives: To explore NMES intensity effects on multifidus thickening in adults with chronic low back pain (CLBP). Methods: Sixty patients with CLBP participated. L4/5 multifidus ultrasound images were obtained and percent thickness change from a resting to a contracted state was determined at baseline with a limb lift and during NMES application. During NMES, the examiner recorded the intensity, in milliampere, when the multifidus first started to thicken as observed with USI. The examiner also recorded the NMES intensity that resulted in no further multifidus thickening (ie, high-tolerance group) or, in cases where maximal thickening was not observed, the NMES intensity of the submaximal contraction (ie, low-tolerance group). Differences between participants with high versus low NMES tolerance were evaluated. Results: During NMES, the multifidus began thickening at a higher intensity for the high-tolerance group (n = 39), that is, 34 mA, compared with the low-tolerance group (n = 21), that is, 32 mA ( P = .001). A greater mean intensity in the high-tolerance group, that is, 62 mA, as compared to 45 mA in the low-tolerance group, resulted in a larger percent thickness change, that is, 30.89% compared to 20.60%, respectively ( P < .001). Conclusions: Results provide clinicians with NMES intensity targets to facilitate multifidus muscle thickening, which provides insight into muscle activity.

Recent studies show that vitamin D deficiency may be responsible for muscle atrophy. The purpose of this study was to investigate markers of muscle atrophy, signalling proteins, and mitochondrial capacity in patients with chronic low back pain with a focus on gender and serum vitamin D level. The study involved patients with chronic low back pain (LBP) qualified for posterior lumbar interbody fusion (PLIF). Patients were divided into three groups: supplemented (SUPL) with vitamin D (3200 IU/day for 5 weeks), placebo with normal levels of vitamin D (SUF), and the placebo group with vitamin D deficiency (DEF). The marker of muscle atrophy including atrogin-1 and protein content for IGF-1, Akt, FOXO3a, PGC-1α, and citrate synthase (CS) activity were determined in collected multifidus muscle. In the paraspinal muscle, IGF-1 levels were higher in the SUF group as compared to both the SUPL and DEF groups (p<0.05). In the SUPL group, we found significantly increased protein content for pAkt (p<0.05) and decreased level of FOXO3a (p<0.05). Atrogin-1 content was significantly different between men and women (p<0.05). The protein content of PGC-1α was significantly higher in the SUF group as compared to the DEF group (p<0.05). CS activity in the paraspinal muscle was higher in the SUPL group than in the DEF group (p<0.05). Our results suggest that vitamin D deficiency is associated with elevated oxidative stress, muscle atrophy, and reduced mitochondrial function in the multifidus muscle. Therefore, vitamin D-deficient LBP patients might have reduced possibilities on early and effective rehabilitation after PLIF surgery.
