Abstract
PURPOSE OF REVIEW Lumbar facet pain is generally considered to be one of the major causes of chronic low back pain. Each lumbar facet joint is innervated by the medial branch of the posterior spinal nerve from its own level and above. Radiofrequency (RF) of the medial branch of the posterior branch of the spinal nerve is an effective method for the treatment of lumbar facet pain. RF technology is diverse, including traditional radiofrequency (TRF), pulsed radiofrequency (PRF), cooled radiofrequency (CRF), low-temperature plasma radiofrequency ablation (CA), and other treatment methods. The purpose of this paper is to compare the efficacy of different radiofrequency techniques and to analyze the reasons for this in the context of anatomy. RECENT FINDINGS There have been studies confirming the differences in efficacy of different RF techniques. However, most of the studies only compared two RF techniques, not four techniques, TRF, CRF, PRF, and CA, and did not analyze the reasons for the differences in efficacy. This article reviews the differences in the efficacy of the above four RF techniques, clarifies that the differences are mainly due to the inability to precisely localize the medial branch of the posterior branch of the spinal nerve, analyzes the reasons for the inability to precisely localize the posterior branch of the spinal nerve in conjunction with anatomy, and proposes that the development of RF technology for lumbar facet pain requires more in-depth anatomical, imaging, and clinical studies.

Image-Guided Minimally Invasive Treatment Options for Degenerative Lumbar Spine Disease: A Practical Overview of Current Possibilities. Diagnostics (Basel) 2024; 14:1147. [PMID: 38893672 PMCID: PMC11171713 DOI: 10.3390/diagnostics14111147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 05/20/2024] [Accepted: 05/24/2024] [Indexed: 06/21/2024] Open
Abstract
Lumbar back pain is one of the main causes of disability around the world. Most patients will complain of back pain at least once in their lifetime. The degenerative spine is considered the main cause and is extremely common in the elderly population. Consequently, treatment-related costs are a major burden to the healthcare system in developed and undeveloped countries. After the failure of conservative treatments or to avoid daily chronic drug intake, invasive treatments should be suggested. In a world where many patients reject surgery and prefer minimally invasive procedures, interventional radiology is pivotal in pain management and could represent a bridge between medical therapy and surgical treatment. We herein report the different image-guided procedures that can be used to manage degenerative spine-related low back pain. Particularly, we will focus on indications, different techniques, and treatment outcomes reported in the literature. This literature review focuses on the different minimally invasive percutaneous treatments currently available, underlining the central role of radiologists having the capability to use high-end imaging technology for diagnosis and subsequent treatment, allowing a global approach, reducing unnecessary surgeries and prolonged pain-reliever drug intake with their consequent related complications, improving patients' quality of life, and reducing the economic burden.

Abstract
BACKGROUND Lumbosacral radicular syndrome (LRS) is probably the most frequent neuropathic pain syndrome, exaggerating medical and economy burden on developing countries, such as Vietnam. As a result, the urgence to find an approach which is both affordable and effective always puts great demand on medical researchers. OBJECTIVES Evaluate the effectiveness of transforaminal pulsed radiofrequency (PRF) stimulation on the dorsal root ganglion (DRG) and epidural steroid injection (ESI) in management of chronic lumbosacral radiculopathy. METHODS Seventy-six patients with chronic radicular pain were performed transforaminal PRF + ESI by neurosurgeons. Demographic characteristics and surgical outcomes were recorded on admission, pre-procedural and post-procedural for 1-month, 3-month, 6-month and 12-month follow-up. Primary outcome was measured by using Visual Analogue Scale (VAS), Oswestry disability index (ODI) and Straight Leg Raising Test (SLRT). Secondary outcome was subjectively collected based on short assessment of patients' satisfaction (SAPS). RESULTS Patients who received transforaminal PRF and ESI showed significant improvements on all three evaluation tools (VAS, ODI, SLRT), compared to that before treatment (p<0.001). Pain relief was achievable and long-lasting, which met patients' expectation. No significant complications were observed for 12 months follow-up. CONCLUSION Transforaminal PRF combined with ESI in management of lumbosacral radiculopathy should be a good method of choice for its effectiveness and safety in management of pain.

Abstract
(1) Background: Osteoarthritis (OA) is a debilitating joint disease. The are several therapies available for OA. According to current knowledge, the combination of Platelet-Rich Plasma (PRP) and Pulsed Radiofrequency (PRF) can be applied in the treatment of pain of nociceptive origin due to peripheral tissue damage. (2) Methods: We performed a narrative review identifying the articles by searching electronic databases. A retrospective analysis of patients with OA treated with PRF and PRP in "Vito Fazzi" Hospital (Lecce, Italy) was performed. (3) Results: A total of four publications on the use of PRP and PRF in degenerative joint arthritis were included in our review. In our experience, two patients with OA were treated with PRP and PRF after unsuccessful conservative treatment. Patient pain score, daily activity ability, active range of activity, and muscle strength improved after treatment. Patients reported a higher level of satisfaction. No major adverse events were reported. (4) Conclusions: The goal of the combined application of the two treatments is to make full use of the analgesic effect of PRF and the repairing effect of PRP. At present, the therapeutic potential of PRP and PRF in OA remains unmet.

Abstract
BACKGROUND Lumbar facet joint pain is a common disorder. The main symptom is chronic lumbar pain, which can reduce quality of life. Radiofrequency has often been used to treat lumbar facet joint pain. However, the effectiveness of this technique has been controversial. This study was conducted to compare the effectiveness of pulsed radiofrequency (PRF) and radiofrequency denervation (RD) for lumbar facet joint pain. METHODS One hundred and forty-two patients with lumbar facet joint pain were allocated to two treatment groups: PRF group (N = 72) and RD group (N = 70). Patients enrolled in the study were assessed using a visual analogue scale (VAS), Roland-Morris questionnaire (RMQ), Oswestry disability index (ODI) and Short-Form 36 (SF-36) questionnaire before therapy, 3 months and 12 months later. RESULTS There were no significant differences in VAS, RMQ score, ODI score and SF-36 score at 3 months (p > 0.05). Significant differences in pain control were observed in both groups at 12 months (3.09 ± 1.72 vs. 2.37 ± 1.22, p = 0.006). There was a significant difference in RMQ score (11.58 ± 3.58 vs. 8.17 ± 2.34, p < 0.001) and ODI score (43.65 ± 11.01 vs. 35.42 ± 11.32, p < 0.001) at 12 months. The total SF-36 score was higher in the RD group than in the PRF group at 12 months (58.45 ± 6.97 vs. 69.36 ± 6.43, p < 0.001). In terms of complications, skin numbness occurred in three patients. Mild pain such as burning and pinking at the puncture site in two patients. One patient experienced a decrease in back muscle strength and back muscle fatigue. These complications disappeared in 3 weeks without any treatment. There were no serious adverse events in the PRF group. CONCLUSION Radiofrequency is an effective and safe treatment option for patients with lumbar facet joint pain. RD could provide good and lasting pain relief, with significant improvement in lumbar function and quality of life at long-term follow-up.

Abstract
Lumbar facet syndrome stands out as a significant cause for the increasing prevalence of back pain complaints. Alternatives such as radiofrequency (RF) ablation may be a therapeutic option to relieve the chronic pain associated with this condition. It is critical to analyze the effectiveness of lumbar facet syndrome treatment using the traditional RF ablation technique and the relief generated by it in chronic low back pain (CLBP). This study is a systematic review using the following inclusion criteria: title, observational studies, clinical trials, controlled clinical trials, clinical studies, and publications over the last 17 years (from 2005 to 2022). The exclusion criteria included papers addressing other themes and review articles. The databases used for data collection included the Medical Literature Analysis and Retrieval System Online (Medline), PubMed, Scientific Electronic Library Online (SciELO), Lilacs, and Biblioteca Virtual em Saúde (Virtual Health Library in Portuguese). The query used the following terms: facet, pain, lumbar, and radiofrequency. The application of these filters yielded 142 studies, and 12 were included in this review. Most studies indicated that the traditional RF ablation technique was beneficial in relieving CLBP refractory to conservative treatment.

Abstract
Facet joint osteoarthritis (OA) is the most frequent form of facet joint syndrome. Medical history, referred pain patterns, physical examination, and diagnostic imaging studies (standard radiographs, magnetic resonance imaging, computed tomography and single-photon emission computed tomography) may suggest but not confirm lumbar facet joint (LFJ) syndrome as a source of low back pain (LBP). However, the diagnosis and treatment of facet joint syndrome is still controversial and needs further study. It is widely acknowledged that block with local anesthetic is perhaps the most effective method to establish a diagnosis of pain from LFJ. Particularly, there are different rates of success among different populations selected for diagnostic block with various positive criteria. Currently, in addition to conservative treatments for pain such as painkillers, functional exercises, and massage, there are many other methods, including block, denervation of the nerves that innervate the joints by radiofrequency, freezing or endoscopy, and injections. Due to the limited duration of pain relief from neurolysis of medial branch, many scholars have recently turned their targets to dorsal roots and LFJ capsules. Therefore, we reviewed the latest research progress of facet joint syndrome from diagnosis to treatment.

Abstract
Background Low back pain is the leading cause of job-related disabilities. The zygapophyseal (facet) joint has been identified as a cause of spinal pain in 15%–45% of individuals. Radiofrequency ablation (RFA) to the facet joints of the lumbar, cervical and thoracic regions and discussion of the 2-year follow-up results will provide additional data and contribute to understanding the long-term effectiveness of RFA. Methods Patients with cervical, thoracic or low back pain, not accompanied by radicular pain and without primary and/or metastatic disease in the spinal region during radiological evaluation were retrospectively analysed. A total of 1274 patients aged >18 years who had clinical follow-up for at least 1 year and had back pain for >6 months were included in the study. The RFA groups were compared within themselves before and after the application. Moreover, patients who received RFA were compared with those who did not receive RFA (controls). The visual analogue scale and quality-of-life scores of the patients were evaluated. Periodic clinical follow-ups revealed changes in neurological status. Results Of the 774 patients who underwent RFA, 156, 184 and 434 patients had pain in the cervical, thoracic and lumbar and lumbosacral regions, respectively. The control groups consisted of 108, 122 and 270 patients, respectively. No significant difference in any of the baseline demographic variables was observed between the groups (p > 0.05). A significant improvement was found in both visual analogue scale and quality-of-life scores when compared before and after RFA application within the groups. In addition, a significant improvement was found in the RFA group compared with the control group. Conclusions As far as we know, this is the first comparative study of RFA involving the cervical, thoracic and lumbar spinal regions. RFA made it possible to obtain satisfactory results in all three regions. With its increasing popularity and frequency of use, new indications for RFA may emerge. Radiofrequency ablation (RFA) method emerges as a very successful treatment method in patients who do not have an operative pathology but who suffer from chronic pain. Especially, considering the persistent outpatient clinic admissions of patients with persistent low back pain, RFA is a "rescuer" position for most clinicians. The clinical relief of the patients for two years is one of the most critical data clearly demonstrating the long-term success of the procedure.

Abstract
BACKGROUND Lumbosacral radicular pain (LSRP) can be caused by disc herniation, spinal stenosis, and failed back surgery syndrome. The clinical effect of pulsed-radiofrequency (PRF) combined with transforaminal epidural steroid injection (TESI) for radiating pain in different population remains unclear. METHODS We retrospectively reviewed the medical recordings of patients with LSRP caused by different etiologies, who underwent PRF and TESI treatment. The primary clinical outcome was assessed by a 10-point Visual Analog Scale (VAS) pre- and post-treatment. RESULTS A total of 34 LSRP patients were identified and classified into 3 subgroups (disc herniation, spinal stenosis, and failed back surgery syndrome). The overall immediate pain reduction was 4.4 ± 1.1 after procedure. After a median follow-up of 9.5 months, the VAS decreased from 6.5 ± 1.0 to 2.4 ± 1.9 at the last follow-up. CONCLUSION PRF combined with TESI is an effective approach to treat persistent LSRP in distinct population.
