Ablación combinada por radiofrecuencia continua y pulsada para el alivio del dolor y su seguridad en el dolor facetario cervical

Continuous Versus Combined Continuous and Pulsed Radiofrequency Ablation for Pain Relief and Safety in Cervical Facet-Mediated Pain: A Prospective Randomized Study

Continuous radiofrequency ablation (CRF) is the effective management for cervical facet joint pain but related with neuropathic symptoms in post-radiofrequency period. Additionally, pulse radiofrequency ablation (PRF) provides relief of neuropathic symptoms. However, the effect of CRF followed by PRF has yet to be validated

Descripción general del estudio

Descripción detallada

One prevalent and incapacitating problem seen in pain treatment therapy is chronic neck pain originating from the cervical facet joints. (1). Cervical facet joint pain was shown to be 49% common in a recent study (2). Depending on the level of the cervical facet joint, a facet referral pattern is characteristic of cervical facet joint discomfort (3,4). Radiofrequency (RF) ablation of the medial branch nerves is a proven, minimally invasive therapeutic option for long-lasting pain alleviation once a good response to diagnostic cervical medial branch blocks validates the diagnosis. Cervical facet joint pain has been successfully treated with traditional continuous radiofrequency ablation (RFA) of the cervical medial branches (5). Regretfully, even with sufficient analgesia, over 40% of patients undergoing RFA experience negative side effects, including post-procedural sensory side effects like numbness, dysesthesia, and hypersensitivity. 6,7). As a result, Continuous radiofrequency ablation (CRF) is the established minimally invasive treatment for chronic facet-mediated spinal pain once diagnostic medial branch blocks confirm the pain source, producing a thermal lesion at the target nerve to interrupt nociceptive transmission. Manchikanti et al. rated continuous RFA as Level II evidence for managing chronic spinal pain from the facet joints, reflecting its established role in clinical practice (6). However, despite its efficacy, more than 40% of patients undergoing CRF of the cervical medial branches experience post-procedural sensory side effects such as numbness, dysesthesia, and hypersensitivity (7,8) prompting interest in alternative radiofrequency strategies that preserve analgesic benefit while reducing these neuropathic effects. Combining continuous and pulsed radiofrequency (CPRF) has been proposed as a strategy to preserve the analgesic effect achieved with thermal ablation while reducing the incidence of post-procedural neuropathic side effects through the added neuromodulatory pulsed phase (9). However, there are no studies comparing the effectiveness and safety of pulse versus combined radiofrequency ablation in the cervical facet joint. This study was designed to compare the effectiveness and safety of continuous radiofrequency (CRF) alone versus combined continuous and pulsed radiofrequency (CPRF) in patients with chronic cervical facet joint pain.

Comparador activo: Flouroscopic guidance cervical medial branch continous RF ablation

After the patient lying prone we obtaining the posterior approach with PA view then lateral 15 degrees the C shaped edge of the cervical vertebrae were appeared and then we advance the needle till reaching this C shaped till hitting the bone then slipping the active tip slightly therafter we obtaining lateral view to determine the depth of the needle over the cervical pedicle.

patients in the continous radiofrequency group will be underwent continous radiofrequency at 80°C for 90 seconds for 2 cycles

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
neck disability index pre and post-intervention between comparison groups
Periodo de tiempo: 6 months

Neck disability index : It contains ten sectors: seven sectors related to everyday existing behaviors, two sectors correlated to pain, and one sector correlated to concentration. All items are marked from 0 to 5. A mark of 0 denotes the maximum level of function, while a mark of 5 indicates the bottom level of function. The maximum mark is 50, and a greater mark relates to an increased level of disability.
