Pain radiofrequency denervation

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...

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...

OBJECTIVES: The sacroiliac joint (SIJ) is the third most common cause of low back pain. The treatment of SIJ-induced pain is often conservative. When conservative treatments fail, interventional treatment methods, such as intra-articular injection or radiofrequency (RF) denervation are applied. Recently, in addition to the success of this interventional treatment applied, increased patient satisfaction and quality of life after treatment have also gained importance. The aim of this retrospective study was to evaluate pain management and improvement in the quality of life in patients with SIJ pain who underwent RF denervation with the simplicity probe...

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)...

INTRODUCTION: A modified Delphi strategy was implemented for obtaining recommendations that could be useful in the management of percutaneous radiofrequency treatment of lumbar facet joint syndrome, as the literature on the argument was poor in quality. METHODS: An Italian research team conducted a comprehensive literature search, defined the investigation topics (diagnosis, treatment, and outcome evaluation), and developed an explorative semi-structured questionnaire...

Interventional pain management (IPM) options for refractory neuropathic pain (NP) have recently increased with availability of peripheral nerve stimulation (PNS) equipment and expertise. Given a lack of high-quality evidence and guidelines on this topic, we sought to understand the perception of physicians with expertise in treating NP regarding IPM and the role of PNS. We emailed a survey in March 2022 to international NP experts including pain medicine physicians, researchers, and leaders of 11 professional pain societies...

The aim of the study was to evaluate the effectiveness of radiofrequency denervation (neuroablation) of the suprascapular nerve in the treatment process of omalgia in patients with degenerative and dystrophic disorders of the shoulder joint. 31 patients (31 joints were researched) took the treatment and analyzed their data in the rehabilitation department of the State Institution "Institute of Traumatology and Orthopedics of the National Academy of Medical Sciences of Ukraine" from 2019 to 2021. X-ray assessment was performed to find out the stage of the disease according to the classification of M...

Chronic low back pain is often due to L5S1 instability resulting in facet joint syndrome. Patients suffering from low back pain may also have a gait pattern characterized by a reduced speed and a shorter, asymmetrical step in order to reduce pain. This case is of a patient with L5S1 instability that occurred after L1 to L5 lumbar stabilization who was treated with radiofrequency (RF) denervation of the medial branch of L5S1 bilaterally. RF ablation outcome was tested by comparing its impact on pain, function, quality of life, and on gait pattern, before and 1 month after the procedure...

PURPOSE OF REVIEW: Chronic pelvic pain syndrome (CPPS) is a common yet complex disease in the field of urology, gynecology, and pain management. This review article summarizes the anatomy and physiology of CPP with an in-depth discussion of established and emerging interventional treatment options. RECENT FINDINGS: Though psychosocial variables play a significant role in the development and propagation of CPPS, interventional treatment strategies are available to ameliorate symptoms...

BACKGROUND: Sacroiliac joint (SIJ) pain is a common source of low back pain. Previously reported management strategies for this pain include conservative treatment, SIJ injection, radiofrequency denervation ablation, and SIJ fusion. Herein, we describe the use of biportal endoscopic radiofrequency ablation (BERA) to treat patients with low back pain. METHODS: We included 16 patients who underwent BERA from April 2018 to June 2020. We marked the S1, S2, and S3 foramina and the SIJ line under fluoroscopy...

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...

STUDY DESIGN: Systematic review. OBJECTIVE: To investigate the efficacy of nonsurgical interventional treatments for chronic low back pain (LBP) caused by facet joint syndrome (FJS). METHODS: A systematic review of the literature was conducted to identify studies that compared interventional treatments for LBP due to FJS among them, with usual care or sham procedures. Studies were evaluated for pain, physical function, disability, quality of life and employment status...

BACKGROUND: Lumbar facet joint (LFJ) pain is the most common cause of low back pain in the elderly. Denervation of the medial branch of the spinal dorsal ramus can theoretically achieve long-term pain relief. Yet there is little evidence of high-level prospective randomized controlled research. OBJECTIVES: To observe the effect of radiofrequency (RF) denervation of the medial branch of the spinal dorsal ramus on LFJ pain in the elderly. STUDY DESIGN: A prospective randomized controlled study...

BACKGROUND: Clinical outcomes following lumbar medial branch radiofrequency ablation (RFA) have been inconsistent. One possible reason is less-than-optimal placement of the electrode along the medial branch at the lateral neck of superior articular process (SAP). Needle angles that define optimal placement (i.e., parallel to the medial branch) may be helpful for consistent technical performance of RFA. Despite its importance, there is a lack of anatomical studies that quantify RFA needle placement angles...

BACKGROUND: Endovascular renal denervation reduces blood pressure (BP). We explored an alternative approach to renal denervation using radiofrequency energy delivered across the renal pelvis utilizing the natural orifice of the urethra and the ureters. METHODS: This open-label, single-arm feasibility study enrolled patients with uncontrolled hypertension despite antihypertensive drug therapy. The primary effectiveness endpoint was the change in ambulatory daytime systolic BP (SBP) 2 months following renal pelvic denervation...

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...

Radiofrequency denervation of the zygapophysial (facet) joints is a frequently performed procedure for chronic low back pain. However, cryoablation represents a novel therapeutic approach for this condition. We observed and analyzed 3 cases with confirmed positive lumbar facet joint syndrome. Our results show a significant improvement in the clinical state of the patients in the first and third months after the procedure. The 6-month follow-up examination demonstrates a recurrence of pain and a gradual deterioration in the quality of life with a lasting partial pain-relief effect...
