RESUMEN
BACKGROUND: Recent advancements in cervical interlaminar epidural steroid injections have given rise to the modified paramedian interlaminar (mPIL) approach. The objective of this study was to perform an analysis of the contrast spread pattern within the cervical epidural space, taking into account different needle tip positions in the mPIL approach. METHODS: A total of 48 patients were included in the study and randomly assigned to either the medial or lateral group based on the needle tip's position in the anterior-posterior view. The primary outcome measured was the contrast flow under fluoroscopic visualization. As a secondary outcome, we analyzed the location of the needle tip position in both lateral and contralateral oblique views. Clinical effectiveness was assessed by measuring pain intensity and functional disability post-procedure. RESULTS: Significant disparities were noted in the ventral distribution of contrast between the medial and lateral groups. In the lateral images, needle tips in the lateral group were positioned more ventrally compared to those in the medial group. Both groups exhibited statistically significant improvements in neck and radicular pain, as well as functional status, 4 weeks after treatment, with no significant differences between them. CONCLUSIONS: Our results suggest that the ventral dispersion of contrast material during cervical interlaminar epidural steroid injections using the mPIL approach may vary depending on the needle tip location.
RESUMEN
Background and Objectives: Local infiltration analgesia (LIA) represents a potential approach to reducing pain in patients undergoing total hip arthroplasty (THA). The pericapsular nerve group (PENG) block also provides adequate analgesia for fractures and THA. As most hip surgeries use a lateral incision, affecting the cutaneous supply by branches of the lateral femoral cutaneous nerve (LFCN), the LFCN block can contribute to postoperative analgesia. However, no studies have investigated the effectiveness of supplemental PENG block combined with LFCN block in patients undergoing LIA after hip fracture surgery. Our study aimed to assess the effectiveness of PENG combined with LFCN block following hip fracture surgery in patients who underwent LIA. Materials and Methods: Forty-six patients were randomly assigned to LIA or PENG + LFCN + LIA groups. The primary outcome was the pain score at rest and during movement at 2, 6, 12, 24, and 48 h postoperatively. The total opioid dose for postoperative analgesia was also measured at the same time points. Secondary outcomes included postoperative cognitive function assessment. Results: The median pain scores at rest and during movement were lower in the PENG + LFCN + LIA group throughout the study periods compared to the LIA group, except at 2 h (at rest) and 48 h (during movement) after surgery. The total fentanyl dose was lower in the PENG + LFCN + LIA group at all time points after surgery when compared to the LIA group. Postoperative delirium incidence and the median abbreviated mental test scores were not significantly different between the two groups. Conclusions: The combination of PENG and LFCN blocks may contribute to enhanced recovery for patients undergoing LIA after hip fracture surgery. However, further well-controlled research is necessary to determine the effectiveness of supplemental PENG combined with LFCN block in addressing cognitive deficits in these patients.

Dexmedetomidine prevents postoperative cognitive dysfunction by inhibiting high-mobility group box 1 (HMGB1), which acts as an inflammatory marker. This study investigated the HMGB1 levels and the cognitive function using a Mini-Cog© score in elderly patients undergoing orthopedic surgery with dexmedetomidine infusion. In total, 128 patients aged ≥ 65 years were analyzed. The patients received saline in the control group and dexmedetomidine in the dexmedetomidine group until the end of surgery. Blood sampling and the Mini-Cog© test were performed before the surgery and on postoperative days 1 and 3. The primary outcomes were the effect of dexmedetomidine on the HMGB1 levels and the Mini-Cog© score in terms of postoperative cognitive function. The Mini-Cog© score over time differed significantly between the groups (p = 0.008), with an increase in the dexmedetomidine group. The postoperative HMGB1 levels increased over time in both groups; however, there was no significant difference between the groups (p = 0.969). The probability of perioperative neurocognitive disorders decreased by 0.48 times as the Mini-Cog© score on postoperative day 3 increased by 1 point. Intraoperative dexmedetomidine has shown an increase in the postoperative Mini-Cog© score. Thus, the Mini-Cog© score is a potential tool for evaluating cognitive function in elderly patients.
RESUMEN
The incidences of herpes zoster (HZ) and postherpetic neuralgia (PHN) are significantly influenced by age. As individuals age, the occurrence of spinal disorders increases, thereby raising the likelihood of HZ and PHN coexistence. Considering this, our study aimed to explore the potential impact of pre-existing spinal disorders at the nerve level where HZ developed, on the severity of zoster-associated pain (ZAP) and the incidence of PHN. For our investigation, we retrospectively analyzed a total of 237 patients who presented with HZ and ZAP at various sensory levels (cervical, thoracic, lumbar, and sacral) with or without pre-existing spinal disorders. The presence or absence of spinal disorders at the sensory level affected by HZ was determined using computed tomography or magnetic resonance imaging. Our study results revealed that the group with spinal disorders at the sensory level where HZ developed did not exhibit an increased incidence of PHN. However, 3-6 months after HZ onset, this same group showed significantly higher ZAP scores compared to the group without spinal disorders. It implies a need for heightened pain management, as the coexistence of these conditions can increase pain severity. This study furnishes an initial standpoint to delve into intricate interactions between two diseases.
RESUMEN
BACKGROUND: A variety of medications are available to manage painful diabetic peripheral neuropathy (DPN), but the proper treatment remains challenging. Accordingly, various neuromodulation modalities have been used. However, no prospective clinical trials have evaluated the use of scrambler therapy (ST) in painful DPN. This study aimed to explore the long-term effects of ST in managing painful DPN. METHODS: The patients received 10 consecutive STs of 45 minutes every 1 to 2 days. The primary outcome was pain score. We measured the visual analog scale (VAS) pain scores at baseline, during ST, immediately after ST, and at 1, 2, 3, and 6 months after ST. The secondary outcomes were Michigan Neuropathy Screening Instrument (MNSI), Semmes-Weinstein monofilament test, and Leeds Assessment of Neuropathic Symptoms and Signs pain scores, which were measured at baseline, immediately after ST, and at 1, 2, 3, and 6 months after ST. RESULTS: VAS scores showed significant improvement at the 8th, 9th, and 10th sessions during ST and 1 month after ST. The MNSI self-report component score was decreased 1 month after the ST. However, all other outcomes did not show significant differences compared to the baseline. CONCLUSION: ST may have short-term effects and limited long-term effects on painful DPN.

BACKGROUND: Erector spinae plane block (ESPB) is a new regional anesthesia. Unilateral biportal endoscopic (UBE) spine surgery, a minimal invasive technique, has been performed under not only general anesthesia (GA) but regional anesthesia including spinal anesthesia (SA). The aims of this study were to evaluate the efficacy of ESPB with sedation for UBE lumbar decompression and compare it with GA and SA. METHOD: A retrospective age matched case-control study design was performed. Three groups (20 patients in each group) of patients who underwent UBE lumbar decompressions under each anesthetic method (GA, SA, or ESPB) were formed. The total anesthesia time excluding operation time, postoperative analgesia effects, hospital days, and complications related to anesthetic methods were evaluated. RESULTS: In the ESPB group, all the operations were performed without change of anesthetic methods and without anesthetic complications. But there were no anesthetic effects in the epidural space, which resulted in additional intravenous fentanyl usage. The mean of time from initiation of anesthesia to completion of surgical preparation was 23.3 ± 4.7 min in the ESPB group, which was shorter than 32.3 ± 10.8 min in the GA (p value = 0.001) or 33.3 ± 6.7 min in the SA group (p < 0.001). The proportion of patients requiring first rescue analgesia within 30 min was 30% in the ESPB group, which was lower than 85% in the GA (p < 0.001), but no significant different with 10% in the SA (p = 0.11). The mean of total hospital days in the ESPB was 3.0 ± 0.8, shorter than 3.7 ± 1.8 in the GA (p = 0.02) or 3.8 ± 1.1 in the SA group (p = 0.01). There was no case of postoperative nausea and vomiting in the ESBB even without prophylactic antiemesis. CONCLUSION: ESPB with sedation is a viable anesthetic option for UBE lumbar decompression.

BACKGROUND: Manubriosternal joint (MSJ) disease is a rare cause of anterior chest pain but can be a major sign of systemic arthritic involvement. In patients with ankylosing spondylitis (AS), a type of systemic arthritis, chest pain can be due to MSJ involvement and can be improved by ultrasound-guided corticosteroid injection into the joint. CASE SUMMARY: A 64-year-old man visited our pain clinic complaining of anterior chest pain. There were no abnormal findings on lateral sternum X-ray, but arthritic changes in the MSJ were observed on single-photon emission computed tomography-computed tomography. We performed additional laboratory tests, and he was finally diagnosed with AS. For pain relief, we performed ultrasound-guided intra-articular (IA) corticosteroid injections into the MSJ. After the injections, his pain nearly resolved. CONCLUSION: For patients complaining of anterior chest pain, AS should be considered, and single-photon emission computed tomography-computed tomography can be helpful in diagnosis. In addition, ultrasound-guided IA corticosteroid injections may be effective for pain relief.
RESUMEN
Complex regional pain syndrome (CRPS) is a condition associated with neuropathic pain that causes significant impairment of daily activities and functioning. Nuclear factor kappa B (NFκB) is thought to play an important role in the mechanism of CRPS. Recently, exosomes loaded with super-repressor inhibitory kappa B (Exo-srIκB, IκB; inhibitor of NFκB) have been shown to have potential anti-inflammatory effects in various inflammatory disease models. We investigated the therapeutic effect of Exo-srIκB on a rodent model with chronic post-ischemia pain (CPIP), a representative animal model of Type I CRPS. After intraperitoneal injection of a vehicle, Exo-srIκB, and pregabalin, the paw withdrawal threshold (PWT) was evaluated up to 48 h. Administration of Exo-srIκB increased PWT compared to the vehicle and pregabalin, and the relative densities of p-IκB and IκB showed significant changes compared to the vehicle 24 h after Exo-srIκB injection. The levels of several cytokines and chemokines were reduced by the administration of Exo-srIκB in mice with CPIP. In conclusion, our results showed more specifically the role of NFκB in the pathogenesis of CRPS and provided a theoretical background for novel treatment options for CRPS.
RESUMEN
BACKGROUND: Electromyography has advantages over mechanomyography and acceleromyography. Previously, agreement of the train-of-four counts between acceleromyography and electromyography was found to be fair. The objective of this study was to assess the agreement of posttetanic count including agreement of neuromuscular blockade status (intense block, posttetanic count equal to 0; or deep block, posttetanic count 1 or greater and train-of-four count equal to 0) between acceleromyography and electromyography. METHODS: Thirty-six patients, aged 20 to 65 yr, participated in this study. A dose of 0.6 mg/kg rocuronium, with additional dose of 0.3 mg/kg if required, was administered to the patients. The train-of-four and posttetanic counts were monitored in the contralateral arm using electromyography at the first dorsal interosseus or adductor pollicis, and acceleromyography at the adductor pollicis. Posttetanic count measurements were performed at 6-min intervals; the responses were recorded until the train-of-four count reached 1. The authors evaluated the agreement of degree of neuromuscular blockade (intense or deep block) and that of posttetanic count between acceleromyography and electromyography. RESULTS: The authors analyzed 226 pairs of measurements. The percentage agreement indicating the same neuromuscular blockade status (intense or deep block) between acceleromyography and electromyography was 73%. Cohen's kappa coefficient value was 0.26. After excluding data with acceleromyography-posttetanic counts greater than 15, a total of 184 pairs of posttetanic counts were used to evaluate the agreement between the two monitoring methods. For acceleromyography-posttetanic count, 42 (23%) pairs had the same electromyography-posttetanic count, and 93 (50%) pairs had more than the electromyography-posttetanic count. The mean posttetanic count on electromyography was 38% (95% CI, 20 to 51%) lower than that on acceleromyography (P = 0.0002). CONCLUSIONS: Acceleromyography frequently counted more twitches than electromyography in posttetanic count monitoring. Acceleromyography- and electromyography-posttetanic counts cannot be used interchangeably to assess the degree of neuromuscular blockade.

BACKGROUND: Lumbar transforaminal epidural steroid injections are used widely to alleviate low back radicular pain, but it requires real-time fluoroscopy, which can increase the risk of radiation exposure. Anteroposterior or lateral real-time fluoroscopy can be used during lumbar transforaminal epidural steroid injections, but there have been no comparative studies on the exposure of physicians to radiation from anteroposterior or lateral real-time fluoroscopy. The aim of this study was to compare the cumulative radiation exposure to each body part of the physician according to the method of real-time fluoroscopy when performing lumbar transforaminal epidural steroid injections. METHODS: A single physician performed lumbar transforaminal epidural steroid injections, and 2 groups of patients were formed based on the method used: group A (anteroposterior real-time fluoroscopy) and group L (lateral real-time fluoroscopy). Dosimeters were placed outside the chest, inside the chest, outside the thyroid collar, inside the thyroid collar, outside the groin, inside the groin, outside the lead gloves, and left rim of the glasses. RESULTS: A total of 200 lumbar transforaminal epidural steroid injections were analyzed, and the radiation exposure was measured by cumulative dose equivalents in mSv. The dose equivalents were lower at every level in group A compared with group L except for outside the groin. CONCLUSIONS: The cumulative radiation exposure at all the measurement sites was lower for anteroposterior real-time fluoroscopy compared with lateral real-time fluoroscopy when performing lumbar transforaminal epidural steroid injections, except for outside the groin.

OBJECTIVE: Interlaminar cervical epidural steroid injections (ICESIs) are commonly used to treat axial neck pain and cervical radicular pain. However, local anesthetics can spread to and block the phrenic nerve and upper segments of the thoracic spinal cord where the sympathetic innervation of the lungs emerges. Therefore, changes in lung function may occur following ICESIs. METHODS: The primary outcome measure was the pulmonary function test (PFT) result 30 minutes before and after ICESI with ropivacaine (0.1875% or 0.25%). The secondary outcome measure was the comparison of the pain scores and functional disability between the two concentrations of ropivacaine 4 weeks after the ICESIs. RESULTS: Fifty patients were randomly assigned to either the R1 (0.1875% ropivacaine) or R2 (0.25% ropivacaine) group. No significant difference was observed between the pre-ICESI and 30-minute post-ICESI PFT results within each group, and no difference was observed between the two groups. After 4 weeks of treatment, both groups showed a significant decrease in pain scores and functional disability; however, no significant differences were observed between the two groups. CONCLUSIONS: This study showed no significant change in lung function after ICESIs in either group and no local anesthetic concentration-based difference in the clinical efficacy of the ICESIs.

BACKGROUND: A cervical transforaminal epidural (TFE) steroid injection is a useful treatment option for cervical radicular pain, but it carries a small risk of catastrophic complications. Several studies have reported that cervical facet joint (FJ) steroid injection can reduce cervical radicular pain through an indirect epidural spread. The aim of this retrospective comparative study was to evaluate the pain scores and functional disability in subjects receiving cervical FJ or TFE steroid injection for the treatment of cervical radicular pain due to foraminal stenosis (FS). METHODS: We selected 278 patients 18 years of age and older who underwent cervical FJ (n = 130) or TFE (n= 148) steroid injection for cervical radicular pain. The primary outcomes included pain scores and functional disability during hospital visits one, three, and six months after the initial injection. Secondary outcomes were the proportion of responders and Medication Quantification Scale (MQS) scores. Adverse events and variables correlating with effectiveness one month after the initial injection were also evaluated. RESULTS: The Numeric Rating Scale and Neck Disability Index scores showed a significant improvement one, three, and six months after the initial injection in both groups, with no significant differences between the groups. No significant differences were observed in the success rates of the procedure one, three, and six months after the initial injection for either group. There were no significant differences in MQS between the groups during the follow-up period. Univariate and multivariate logistic regression analyses revealed that the injection method, age, sex, number of injections, FS severity, MQS, pain duration, and the presence of cervical disc herniation were not independent predictors of treatment success. CONCLUSION: The efficacy of FJ steroid injection may not be inferior to that of TFE steroid injection in patients with cervical radicular pain due to FS.

BACKGROUND: Lumbar transforaminal epidural block (TFEB) is an effective treatment modality for radicular pain due to lumbar disc herniation (LDH). The addition of steroids is more effective than local anesthetic alone in TFEBs for patients with LDH. Moreover, the efficacy of TFEBs has been reported to be positively correlated with the volume of injectate. We hypothesized that high-volume TFEBs without steroids effectively alleviate axial back and radicular pain associated with LDH. This study compared the efficacy of high-volume TFEBs with vs. without steroids for the management of the axial and radicular pain caused by LDH. METHODS: A total of 54 patients were randomly assigned to either group L or group D. Patients in group L received 8-mL injections of 0.33% lidocaine only. Patients in group D received 8-mL injections of 0.33% lidocaine with 5 mg of dexamethasone. The primary outcomes were pain intensity at baseline and 4 weeks after the procedure. The secondary outcomes included the change of functional disability between baseline and 4 weeks after the procedure, pain scores during injection, and adverse effects. RESULTS: Both groups showed a significant reduction in axial and radicular pain and improvement in the functional status at the outpatient visit 4 weeks after TFEB. However, there were no significant differences between the groups in terms of changes in back pain (10.00 [20.00] vs. 10.00 [22.50]; P = 0.896) or radicular pain (5.00 [20.00] vs. 10.00 [12.50]; P = 0.871). CONCLUSION: High-volume TFEBs with and without steroid administration yielded similar significant pain reductions and functional improvements among LDH patients 4 weeks after the procedure.

BACKGROUND: Cerebrospinal fluid (CSF) leakage at C1/2 in spontaneous intracranial hypotension (SIH) is rare. Subdural hematoma (SDH), a serious complication of SIH, may lead to neurological deficits. This report presents a case of SDH after spontaneous C1/2 CSF leakage, which was treated with a targeted epidural blood patch (EBP). CASE SUMMARY: A 60-year-old man with no history of trauma was admitted to our hospital with orthostatic headache, nausea, and vomiting. Brain computed tomography imaging revealed bilateral, subacute to chronic SDH. Brain magnetic resonance imaging (MRI) findings were SDH with dural enhancement in the bilateral cerebral convexity and posterior fossa and mild sagging, suggesting SIH. Although the patient underwent burr hole trephination, the patient's orthostatic headache was aggravated. MR myelography led to a suspicion of CSF leakage at C1/2. Therefore, we performed a targeted cervical EBP using an epidural catheter under fluoroscopic guidance. At 5 d after EBP, a follow-up MR myelography revealed a decrease in the interval size of the CSF collected. Although his symptoms improved, the patient still complained of headaches; therefore, we repeated the targeted cervical EBP 6 d after the initial EBP. Subsequently, his headache had almost disappeared on the 8th day after the repeated EBP. CONCLUSION: Targeted EBP is an effective treatment for SDH in patients with SIH due to CSF leakage at C1/2.
RESUMEN
PURPOSE: Breast-conserving surgery (BCS) is a surgical method designed to minimize intraoperative tissue injury. Although this technique is minimally invasive, it can cause significant postoperative pain and may be a risk factor for persistent pain. Erector spinae plane block (ESPB) is an easy interfascial plane block for analgesia in patients undergoing breast surgery. The primary outcome was the numeric rating scale scores measured separately on the breast and axilla. Secondary outcomes included correlation between pain score and skin sensitivity test. METHODS: Forty patients were divided into 2 groups (ESPB group and control group). Patients in the ESPB group received an ESPB 30 minutes before the induction of general anesthesia, whereas patients in the control group did not receive any regional analgesia during the perioperative period. RESULTS: Median pain scores of the breast were significantly lower in the ESPB group than that in the control group at 12, 24, and 48 hours after surgery. However, the median pain scores of the axilla were not significantly different between the groups, and the pain score was unrelated to skin sensitivity. CONCLUSION: ESPB can effectively alleviate acute postoperative pain with an opioid-sparing analgesic technique in patients undergoing BCS, and a strong correlation is lacking between pain scores and skin sensitivity test.
RESUMEN
RATIONALE: Recently, collagen therapy has been made available for treating rotator cuff tendon injuries. However, to our knowledge, there are no clinical studies objectively investigating the effect of collagen therapy. PATIENT CONCERNS: A 53-year-old female patient visited our pain clinic because of pain in the right shoulder. Although she had never experienced trauma and had not overused her shoulder and arm, the patient showed limited range of motion with painful arc syndrome. Moreover, the Neer test and Hawkins-Kennedy test were positive with subacromial tenderness. DIAGNOSES: The MRI findings revealed partial tears on the articular surface of the anterior supraspinatus tendon in the rotator cuff. INTERVENTIONS: The patient was treated with injections of exogenous collagen at the site of the partial tear under ultrasound guidance. OUTCOMES: Follow-up MRI after injection of collagen revealed healing of the previous partial rupture of the tendon without any complications. Moreover, the patient reported reduction in pain and improvement in the movement of her shoulder during the follow-up period. LESSONS: In this report, we demonstrate healing of a partial tear of the supraspinatus tendon in the rotator cuff after injection of exogenous collagen, as confirmed by MRI.

BACKGROUND: Spine interventionists frequently employ fluoroscopy to guide injection procedures. The increase in fluoroscopically guided procedures in recent years has led to a growing concern about radiation exposure. A new method of covering the C-arm tube with a lead apron has been suggested to reduce radiation exposure. This study aimed to compare the radiation exposure when performing lumbar transforaminal epidural steroid injections (TFESIs) using this new method to a control group. METHODS: A total of 200 patients who underwent lumbar TFESIs by a single physician were recruited. Patients were divided into 2 groups, the new method group (group A) and the control group (groupâC), and the amount of radiation exposure was compared. The dosimetry badge locations were marked as outside of apron, inside of apron, outside of thyroid collar, inside of thyroid collar, ring, and glasses. RESULTS: The cumulative dose equivalents of all the measurement sites were reduced in group A compared with group C, and the most reduced site was inside the thyroid collar. CONCLUSIONS: Covering the C-arm tube with a lead apron can be effective in reducing the cumulative radiation exposure when performing fluoroscopically guided TFESIs.

PURPOSE: Studies have demonstrated that chronic kidney disease (CKD) is significantly associated with the increased risk of functional difficulty in daily activity and mobility. However, data are less available for association between CKD and functional disability in Asians. METHODS: Using a data from Korea National Health and Nutrition Examination Survey III, we investigated the association of CKD with functional disability in 882 subjects over the age of 65. Disability was identified in activity of daily living (ADL), instrumental ADL (IADL), and visual, hearing, and walking function. The prevalence of disability was evaluated according to the stage of CKD, and multivariate logistic regression analysis was used to calculate the adjusted odds ratios (ORs) and 95% confidence interval (CI) [adjusted ORs (95% CI)] of CKD stage 3a for disability in ADL, IADL, visual, hearing, and walking function. RESULTS: Individuals with CKD stage 3-4 had the higher prevalence of disability ADL, IADL, visual, hearing, and walking function than individuals without CKD. CKD stage 3a was significantly associated with abnormal ADL [1.63 (1.04-2.54)] and visual impairment [1.39 (1.01-1.93)] even after adjusting for DM, hypertension, education, income, marital status, age, and sex. CONCLUSION: The presence of mild CKD was significantly associated with disability in daily activity and multiple function.

BACKGROUND: Vascular calcification (VC) is a risk factor for cardiovascular disease in end-stage renal disease (ESRD) patients undergoing maintenance haemodialysis (MHD). However, evidence is still insufficient about the association between dialysis parameters and VC. Thus, this study was to evaluate association of dialysis parameters with VC. METHODS: We enrolled 297 ESRD patients undergoing MHD at six distinct centers in Korea. Study participants were categorized into 3 groups by the scoring system of abdominal aortic calcification based on lateral lumbar radiography (no VC group: 0, mild VC group: 1-7 and advanced VC group: 8-24). We compared the features of dialysis parameters according to the severity of VC. Multivariate logistic regression analysis was used to calculate adjusted odd ratios (ORs) and 95% confidence interval (CI) for mild and advanced VC in each haemodialysis parameter (adjusted OR [95% CI]). RESULTS: Pooled Kt/V (spKt/V), equilibrated Kt/V (eKt/V), standard Kt/V (stdKt/V) and the proportion of haemodiafiltration were increased along with the severity of VC. Multivariate regression analysis indicated that advanced VC was positively associated with spKt/V (5.27 [1.51-18.41]), eKt/V (6.16 [1.45-26.10]), stdKt/V (10.67 [1.74-65.52]) and haemodiafiltration (3.27 [1.74 to 6.16]). CONCLUSION: High dose dialysis and haemodiafiltration were significantly associated with advanced VC.

BACKGROUND: Pulsed radiofrequency (PRF) is a treatment modality that alleviates radicular pain by intermittently applying high-frequency currents adjacent to the dorsal root ganglion. There has been no comparative study on analgesic effect according to the position of the needle tip in PRF treatment. The objective of this study is to evaluate the clinical outcomes of PRF according to the needle tip position. METHODS: Patients were classified into 2 groups (group IP [group inside of pedicle] and group OP [group outside of pedicle]) based on needle tip position in the anteroposterior view of fluoroscopy. In the anteroposterior view, the needle tip was advanced medially further than the lateral aspect of the corresponding pedicle in group IP; however, in group OP, the needle tip was not advanced. The treatment outcomes and pain scores were evaluated at 4, 8, and 12 weeks after applying PRF. RESULTS: At 4, 8, and 12 weeks, there were no significant differences between the successful response rate and numerical rating scale score ratio. CONCLUSIONS: The analgesic efficacy of PRF treatment did not differ with the needle tip position.
