Facet radiofrequence

Low back pain is one of the most common complaints in primary care. This pain is usually nonspecific and musculoskeletal. However, identification and exclusion of specific causes of pain as early as possible are important for specialists since their underestimation can sometimes lead to life-threatening consequences. The authors analyze literature data on the key facts of anamnesis («red flags»), management of patients with low back pain with emphasis on modern concepts and recommendations for diagnostics, identifying the dominant nature and cause of pain, differential diagnosis, and diagnostic significance of neuroimaging...

Lumbar facet joints have been identified as a potential source of chronic low back pain (LBP) in 15% to 45% of patients, with the prevalence of such pain varying based on specific populations and settings examined. Lumbar facet joint interventions are useful in the diagnosis as well as the therapeutic management of chronic LBP. Radiofrequency ablation (RFA) of medial branch nerves is recognized as a safe and effective therapy for chronic facet joint pain in the lumbosacral spine, and its efficacy has already been established...

BACKGROUND: Cervical facet joint disease is a common source of neck pain and its prevalence increases with aging. Conservative multimodal management options (e.g., strengthening of neck muscles, non-steroidal anti-inflammatory medications, massage, and thermal modalities) often fail to relieve pain. Cervical medial branch nerve (CMBN) radiofrequency neurotomy (RFN) is an effective minimally invasive technique for treating chronic neck pain secondary to facet joint disease. An end-on approach for this procedure has been proposed that may be technically easier and require less time while reducing post-procedural discomfort...

OBJECTIVES: The aim of this study was to evaluate the efficacy of consecutive facet medial branch (FMB) radiofrequency denervation (RFD) and dorsal root ganglion pulse radiofrequency (DRG PRF) therapy in patients with chronic lumbar facet joint pain. METHODS: The study included 27 patients with chronic lumbar pain who had ≥50% pain reduction after FMB block for suspected lumbar facet syndrome and subsequently underwent FMB RFD together with PRF to the adjacent DRG...

INTRODUCTION: Lumbar puncture is an important medical procedure for various diagnostics and therapies, but it can be hazardous due to individual variances in subcutaneous soft tissue, especially in the elderly and obese. Our research describes a novel robot-assisted puncture system that automatically controls and maintains the probe at the target tissue layer through a process of tissue recognition. METHODS: The system comprises a robotic system and a master computer...

BACKGROUND: Lumbar facet arthropathy is one of the leading causes of back pain. Lumbar radiofrequency lesioning is a therapy for lumbar facet arthropathy that uses heat to ablate the transmission of nerve signals from the medial branches of the spinal nerves associated with the corresponding painful lumbar joints. OBJECTIVES: The present investigation evaluated the outcomes of patients undergoing lumbar radiofrequency ablation at an academic pain program with a special focus on the influence of gender and obesity...

BACKGROUND: Extensive research into potential sources of thoracic pain with or without referred pain into the chest wall has demonstrated that thoracic facet joints can be a potential source of pain confirmed by precise, diagnostic blocks.The objective of this systematic review and meta-analysis is to evaluate the effectiveness of medial branch blocks and radiofrequency neurotomy as a therapeutic thoracic facet joint intervention. METHODS: Systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies of medial branch blocks and the radiofrequency neurotomy in managing thoracic pain utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was performed...

With technical advancements, the full-endoscopic transforaminal approach for lumbar discectomy (ETALD) is gaining popularity. This technique utilizes various tools and instruments, including a dilator, a beveled working sleeve, and an endoscope with a 20-degree angle and 177 mm length, equipped with a 9.3-diameter oval shaft and a 5.6 mm diameter working channel. Additionally, the procedure involves using a Kerrison punch (5.5 mm), rongeur (3-4 mm), punch (5.4 mm), tip control radioablator applying a radiofrequency current of 4 MHz, fluid control irrigation and suction pump device, 5...

Radiofrequency ablation of the medial branch is commonly used to treat chronic low back pain involving facet joints, which accounts for 12% to 37% of the total cases of chronic low back pain. An adverse effect of this procedure is the denervation of the multifidus muscle, which may lead to its atrophy which can affect the spine and possibly disc degeneration. This study aims to quantify changes in joint angles and loading caused by multifidus denervation after radiofrequency ablation. AnyBody model of the torso was used to evaluate intervertebral joints in flexion, lateral bending, and torsion...

INTRODUCTION: Pain originating from the lumbar facets can be defined as pain that arises from the innervated structures comprising the joint: the subchondral bone, synovium, synovial folds, and joint capsule. Reported prevalence rates range from 4.8% to over 50% among patients with mechanical low back pain, with diagnosis heavily dependent on the criteria employed. In well-designed studies, the prevalence is generally between 10% and 20%, increasing with age. METHODS: The literature on the diagnosis and treatment of lumbar facet joint pain was retrieved and summarized...

BACKGROUND: Lumbar medial branch radiofrequency ablation (LRFA) and intraarticular facet steroid injections (FJI) are commonly performed for recalcitrant facet joint-mediated pain. However, no study has compared clinical outcomes of the two treatments in patients selected using dual medial branch blocks (MBBs) with an 80% relief threshold. OBJECTIVE: Compare the effectiveness of cooled LRFA (C-LRFA) to FIJ as assessed by pain and functional improvements. DESIGN: Prospective randomized comparative trial...

BACKGROUND: Lumbar medial branch radiofrequency ablation (RFA) is a common intervention to manage chronic axial low back pain originating from the facet joints. A more parasagittal approach targeting the posterior half of the lateral neck of superior articular process (SAP) was previously proposed. However, specific needle angles to achieve parallel placement at this target site have not been investigated. OBJECTIVE: To quantify and compare the needle angles, on posterior and lateral views, to achieve parallel placement of electrodes along the medial branch at the posterior half of the lateral neck of SAP at each lumbar vertebral level (L1-L5) and sacrum...

BACKGROUND: Chronic cervical facet joint pain is a leading cause of pain and disability. In patients nonresponsive to conservative treatment, cervical facet radiofrequency ablation (RFA) has shown to be efficacious. However, the conventional RFA technique can be cumbersome. A novel RFA technique with a multitined cannula allows for a lateral approach and represents an attractive alternative option for cervical facet RFA. It offers a potentially shorter, less cumbersome procedure, with consequently less x-ray exposure and patient discomfort than the conventional cervical RFA...

STUDY DESIGN: A scoping review. OBJECTIVE: We aimed to identify and describe the factors associated with the patient-reported response after lumbar intra-articular facet joint (FJ) injections or medial branch blocks (MBBs). SUMMARY OF BACKGROUND DATA: FJ osteoarthritis is among the most common causes of chronic low back pain. Management often includes FJ intra-articular injection and MBBs (which may be followed by radiofrequency ablation of the nerves innervating these joints)...

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)...

BACKGROUND: Axial facet joint interventions (e.g., medial branch block and radiofrequency ablation, facet joint intra-articular injection) are commonly performed for managing chronic spinal pain. Although traditionally performed with fluoroscopy or computed tomography (CT) guidance, ultrasound-guided techniques have also been developed for these interventions. AIMS: The aim of this study is to present contemporary ultrasound-guided techniques for facet joint interventions and synthesize data addressing their accuracy, safety, and efficacy...
