UNASSIGNED: Pain management for spinal facet joint (SFJ) and sacroiliac joint (SIJ) pain is challenging, often requiring interventions like radiofrequency ablation (RFA) or corticosteroid injections (CI). This study aims to assess and compare the effectiveness of CI and RFA in treating SFJ and SIJ pain. We combine these treatments due to their shared pathophysiology, similar therapeutic interventions, and the necessity for an integrated approach to spinal pain management.
UNASSIGNED: Literature search from PubMed, Scopus, CENTRAL and Google Scholar for published studies upto 31st December 2023, and reporting data of patients who were treated using CI of RFA for SFJ and SIJ pain. Pooled standardized mean difference (SMD) with a 95% Confidence Interval (CI) was calculated.
UNASSIGNED: Our meta-analysis incorporated thirteen studies. Overall, patients, treated with CI had a higher pain intensity score compared to patients treated with RFA (SMD=0.92; 95% CI: 0.19 to 1.65) at 3 months, and at 6 months (SMD=1.53; 95% CI: 0.66 to 2.40) after the treatment. No significant association was reported at 12 months (SMD=1.47; 95% CI: -0.03 to 2.97). Subgroup analysis based on joint types revealed increased pain intensity scores in patients who were treated with CI for SIJ (SMD=1.25; 95% CI: 0.39 to 2.11) and SFJ (SMD=1.33; 95% CI: 0.09 to 2.57) pain. A negative but not significant effect was detected in patients, treated with CI for cervical joint pain (SMD=-0.40; 95% CI: -0.90 to 0.10). Patients treated with CI exhibited higher functional disability score compared to patients treated with RFA at 3 months (SMD=1.28; 95% CI: 0.20 to 2.35) post-treatment.
UNASSIGNED: This study suggests that RFA may offer superior pain relief with longer duration compared to steroid injections for spinal facet and sacroiliac joint pain. Decision regarding specific interventions should be individualized and consider patient preferences, clinical context, and potential risks.

UNASSIGNED: There were two primary objectives of the study: 1. assessment of the association between diagnostic sacral lateral branches (SLB) blocks and the ensuing numbness in the middle cluneal nerves (MCN) distribution, irrespective of whether the patients had positive or negative responses to blocks. 2. If the consistency of this causal relationship was established, we wanted to investigate a further correlation - hypoesthesia from local anesthetic blocks vs. hypoesthesia from radiofrequency neurotomy (RFN) vs. outcomes.
UNASSIGNED: This is a prospective observational study of sixty consecutive patients with sacroiliac (SI) joint complex pain and failure of previous intraarticular SI joint injection. The patients who had two positive diagnostic SLB blocks defined as ≥ 75% reduction in NRS scores were treated with cooled RFN of the L5 dorsal ramus and S1-S3 lateral branches. The patients were interviewed and evaluated at a one-month post-neurotomy follow-up appointment. Seven patients were also evaluated at a six-month follow-up visit after the procedure.
UNASSIGNED: The primary outcomes of the study were absence/presence of post-procedural buttock hypoesthesia after diagnostic blocks and absence/presence of post-procedural buttock hypoesthesia at one month after a cooled RFN procedure. The secondary outcome measures related to the effectiveness of this procedure and included: pre- and post-procedure NRS scores; ODI scores initially, and at post RFN follow-up; analgesic consumption initially, and at one-month RFN follow-up; patient satisfaction with the cooled RFN treatment. A procedure was considered categorically successful if the patient gained ≥50% pain relief and was satisfied with its results.
UNASSIGNED: 81/84 (96.4%; 95% CI [89.9%, 99.3%]) of the diagnostic SLB blocks lead to temporary sensory deficit to pinprick in the MCN distribution. If the block was positive, 58/58 (100.00%; 95% CI [93.8, 100.00%]) of the procedures led to hypoesthesia. For negative diagnostic blocks, 3/26 (11.5%; 95% CI [2.4%, 30.2%]) procedures lead to no hypoesthesia. The buttock hypoesthesia persisted in all patients with successful cooled RFN one month after this intervention. Among the patients with unsuccessful RFN, only 2/9 (22.2%, 95%CI [2.8%, 60.0]) still had hypoesthesia, but the rest of this group had no sensory deficit on pinprick examination. At 6-months follow-up buttock hypoesthesia had no association with the success of the procedure.The patients\' average NRS scores decreased from baseline 7.1 (SD 1.7) to 4.3 (SD 3.3) at 1-month follow-up after RFN. Categorical success, based on ≥50% pain relief coupled with patients\' satisfaction, was achieved in 12/21 (57.1%; 95% CI [34.0%, 78.2%]) of the subjects. Average ODI percentage score decreased from 41.7% (SD 15.1%) to 31.8% (SD 17.8%) at the primary endpoint of the study.
UNASSIGNED: MCNs provide regular and clinically detectable innervation to the skin area overlaying posterior-medial aspects of the gluteus maximums muscle. Therefore, any technically accurate diagnostic block, irrespective of whether the patients have positive or negative responses, should result in the development of hypoesthesia in the area supplied by the MCNs. Immediately after the completion of the diagnostic procedure, the adequacy of the block should be tested. Absence of hypoesthesia suggests that the block may have been technically inadequate. Numbness in the buttock area innervated by the MCNs may serve as a marker of an adequately performed RFN procedure. If this procedure is unsuccessful in patients who do not develop post-neurotomy numbness in the area supplied by the MCNs, the failure of the intervention may stem from its inaccurate implementation rather than from its inherent ineffectiveness.

OBJECTIVE: Patients frequently complain of low back pain and sacroiliac joint pain (SIP) following total hip arthroplasty (THA). We hypothesized that patients with SIP would display different pelvic incidence (PI) values between standing and relaxed sitting positions, indicative of increased motion in the sacroiliac joints.
METHODS: In this retrospective case-control study, 94 patients who underwent unilateral THA and experienced SIP were compared with 94 control patients without SIP. SIP was confirmed through clinical tests and investigated using biplanar imaging in both standing and sitting positions. The key parameters analyzed included PI, sacral slope (SS), lumbar lordosis (LL), and limb length discrepancy (LLD).
RESULTS: Patients without SIP showed a mean difference in PI of -1.5° (-8°-5°) between standing-to-sitting positions, whereas those with SIP showed a difference of -3.3° (-12°-0°)(P < 0.0001), indicating more motion in the sacroiliac joint during daily activities in the latter group. Patients with SIP showed smaller change in LL between standing-to-sitting positions (mean:6.3°; range:-8°-27°) compared with those without SIP (mean:9.5°; range:-12°-28°)(P = 0.006). No significant differences were noted in functional leg length between patients with (mean:7 mm; range:0-12 mm) and without SIP (mean:7 mm; range:0-11 mm)(P = 0.973).
CONCLUSIONS: This study revealed significant sacroiliac joint motion in patients with SIP post-THA, as indicated by PI changes, increased posterior pelvic tilt, and reduced change in the LL. Contrary to common belief, SIP did not correlate with LLD.

Background: Adult spinal deformity (ASD) patients with concurrent sacroiliac joint (SIJ) pain are susceptible to worse postoperative outcomes. There is scarce literature on the impact of ASD realignment surgery on SIJ pain. Methods: Patients undergoing ASD realignment surgery were included and stratified by the presence of SIJ pain at the baseline (SIJP+) or SIJ pain absence (SIJP-). Mean comparison tests via ANOVA were used to assess baseline differences between both cohorts. Multivariable regression analyses analyzed factors associated with SIJ pain resolution/persistence, factoring in BMI, frailty, disability, and deformity. Results: A total of 464 patients were included, with 30.8% forming the SIJP+ cohort. At the baseline (BL), SIJP+ had worse disability scores, more severe deformity, higher BMI, higher frailty scores, and an increased magnitude of lower limb compensation. SIJP+ patients had higher mechanical complication (14.7 vs. 8.2%, p = 0.024) and reoperation rates (32.4 vs. 20.2%, p = 0.011) at 2 years. SIJP+ patients who subsequently underwent SI fusion achieved disability score outcomes similar to those of their SIJ- counterparts. Multivariable regression analysis revealed that SIJP+ patients who were aligned in the GAP lordosis distribution index were more likely to report symptom resolution at six weeks (OR 1.56, 95% CI: 1.02-2.37, p = 0.039), 1 year (OR 3.21, 2.49-5.33), and 2 years (OR 3.43, 2.41-7.12). SIJP- patients who did not report symptom resolution by 1 year and 2 years were more likely to demonstrate PI-LL > 5° (OR 1.36, 1.07-2.39, p = 0.045) and SVA > 20 mm (OR 1.62, 1.24-1.71 p = 0.017). Conclusions: SIJ pain in ASD patients may result in worsened pain and disability at presentation. Symptom resolution may be achieved in affected patients by adequate postoperative lumbar lordosis restoration.

UNASSIGNED: The most effective injective treatment approach for sacroiliac joint (SIJ) pain remains unclear. Aim of this study was to quantify the safety and effectiveness of the available injective strategies to address SIJ pain.
UNASSIGNED: A systematic review and meta-analysis of the literature was conducted on PubMed, Scopus, and Embase databases from inception until January 2023. Inclusion criteria were studies written in English, comparative and non-comparative studies regardless of the minimum follow-up, and case series on SIJ injections. Safety and efficacy of the different injection therapies for the SIJ were quantified. A meta-analysis was conducted on the available data of the documented injective therapies. The \"Checklist for Measuring Quality\" by Downs and Black was used to assess the risk of bias and the quality of papers.
UNASSIGNED: The literature search retrieved 43 papers (2431 patients): 16 retrospective case series, 2 retrospective comparative studies, 17 prospective case series, 3 prospective comparative studies, and 5 randomized controlled trials. Of the selected studies, 63% examined the effect of steroid injections, 16% of PRP injections, while 21% reported other heterogeneous treatments. The failure rate was 26% in steroid injections and 14% in PRP injections. The meta-analysis showed a statistically significant reduction in pain with the VAS score for both steroids and PRP: steroids improvement at mid-term 3.4 points (p < 0.05), at long-term 3.0 (p < 0.05), PRP improvement at mid-term 2.2 (p = 0.007), at long-term 2.3 points of the VAS pain scale (p = 0.02).
UNASSIGNED: Steroids are the most documented injective approach, with studies showing an overall safety and effectiveness. Still, the high number of failures underlined by some studies suggest the need for alternative procedures. Early PRP data showed promise, but the limitations of the current literature do not allow to clearly define the most suitable injective approach, and further studies are needed to identify the best injective treatment for SIJ patients.

BACKGROUND: Acute injury to the sacroiliac joint (SIJ) can result from high-energy external forces that cause a combination of axial loading and sudden rotational movements, resulting in severe pain that cannot be relieved by regular nonsteroidal anti-inflammatory drugs. The treatment includes injections of steroids and local anesthetics to reduce pain and promote healing. Here, we report the case of a patient with acute sacroiliac pain who did not respond to conventional injection therapy.
METHODS: A 58-year-old male patient who did not exercise regularly experienced pain in his left groin and difficulty walking while kicking on his right leg. He received two injections and manual therapy at a local orthopedic clinic; however, his symptoms did not improve despite taking painkillers.
METHODS: Radiographic images showed no abnormalities. After confirming the cause of onset, pain pattern, physical examination, and tenderness, the patient was diagnosed with an acute SIJ sprain (static blood).
METHODS: At the first visit, a single acupotomy was performed on the seven treatment points identified during the physical examination, and immediate improvement in symptoms was confirmed. From then on, Korean medicine (KM) treatments, such as acupuncture, cupping, chuna, and bee venom pharmacopuncture, were performed.
RESULTS: Immediately after acupotomy, groin pain improved by 80 %, gait immediately normalized, and the patient showed no symptoms at the 9th visit.
CONCLUSIONS: For SIJ-type groin pain that does not respond to existing treatments, immediate relief is achieved after a single acupotomy at the exact treatment point. Therefore, in the future, the importance of identifying a precise treatment point for SIJ pain should be recognized, and the use of Korean medicine treatment techniques, including acupotomy, should be considered.

OBJECTIVE: To evaluate the effectiveness of radiofrequency neurotomy in managing sacroiliac joint pain utilizing a systematic review with meta-analysis of randomized controlled trials (RCTs) and observational studies.
RESULTS: The prevalence of sacroiliac joint pain is estimated at around 25% of low back pain cases, and its diagnosis lacks a gold standard. Treatments include exercise therapy, injections, ablation, and fusion, with variable effectiveness. COVID-19 altered utilization patterns of interventions, including sacroiliac joint procedures, and the evidence for these interventions remains inconclusive. Recently, Medicare has issued its local coverage determinations (LCDs) in the United States, which provides noncoverage of sacroiliac joint radiofrequency neurotomy. Additionally, a recent systematic review of sacroiliac joint injections showed Level III or fair evidence. The sacroiliac joint, a critical axial joint linking the spine and pelvis, contributes to low back pain. Its complex innervation pattern varies among individuals. Sacroiliac joint dysfunction, causing pain and stiffness, arises from diverse factors.The present systematic review and meta-analysis aimed to evaluate radiofrequency neurotomy\'s effectiveness for sacroiliac joint pain management by applying rigorous methodology, considering both RCTs and observational studies. Despite methodological disparities, the evidence from this review, supported by changes in pain scores and functional improvement, suggests Level III evidence with fair recommendation for radiofrequency neurotomy as a treatment option. The review\'s strengths include its comprehensive approach and quality assessment. However, limitations persist, including variations in criteria and technical factors, underscoring the need for further high-quality studies in real-world scenarios.

UNASSIGNED: To formulate the most current, evidence-based recommendations for the clinical and radiologic diagnosis of acute low back pain lasting <4 weeks.
UNASSIGNED: A systematic literature search in PubMed and Google Scholar databases was performed from 2012 to 2022 using the search terms \"acute back pain AND clinical diagnosis\" and \"acute back pain AND radiologic diagnosis\". Screening criteria resulted in a total of 97 papers analyzed. Using the Delphi method and two rounds of voting, the WFNS (World Federation of Neurosurgical Societies) Spine Committee generated ten final consensus statements.
UNASSIGNED: Ten final consensus statements address the clinical diagnosis of acute LBP, including which clinical conditions cause acute LBP and how we can distinguish between the different causes of LBP, including discogenic, facet joint, sacroiliac joint, and myofascial pain. The most important step for the radiologic diagnosis of acute LBP is to evaluate the necessity of radiologic investigation, as well as its timing and the most appropriate type of imaging modality. Importantly, imaging should not be a routine diagnostic tool, unless red flag signs are present. In fact, routine imaging for acute LBP can actually have a negative effect as it may reveal incidental radiographic findings that exacerbate patient fear and anxiety.
UNASSIGNED: Overall, the quality of evidence is not high for most of our consensus statements, and further studies are needed to validate the WFNS Spine Committee recommendations on the clinical and radiographic diagnosis of acute LBP.

UNASSIGNED: Minimally invasive fusion of the sacroiliac joint as treatment for low back pain may reduce pain and improve function compared to non-operative treatment, although clear evidence is lacking. The aim of this trial was to evaluate the effect of minimally invasive sacroiliac joint fusion compared to sham surgery on sacroiliac joint pain reduction.
UNASSIGNED: In this double-blind randomized sham surgery-controlled trial patients with clinical diagnosis of sacroiliac joint pain confirmed with sacroiliac joint injection were included at two university hospitals in Sweden and Norway. Patients were randomized by the operating surgeon at each site to minimally invasive sacroiliac joint fusion or sham surgery. The primary endpoint was group difference in sacroiliac joint pain on the operated side at six months postoperatively, measured by the Numeric Rating Scale (0-10). Un-blinding and primary analysis were performed when all patients had completed six months follow-up. The trial is closed for new participants and was registered at clinicaltrials.gov: NCT03507049.
UNASSIGNED: Between September 1st, 2018 and October 22nd, 2021, 63 patients were randomized, 32 to the surgical group, 31 to the sham group. Mean age was 45 years (range 26-63) and 59 of 63 (94%) patients were female. The mean reduction in the operated sacroiliac joint from baseline to six months postoperative was 2.6 Numeric Rating Scale points in the surgical group and 1.7 points in the sham group (mean between groups difference -1.0 points; 95% CI, -2.2 to 0.3; p = 0.13).
UNASSIGNED: This double-blind randomized controlled trial could not prove that minimally invasive fusion of the sacroiliac joint was superior to sham surgery at six months postoperative.
