Brief summary
In this study, investigators compared the effectiveness of medial branch conventional radiofrequency application and combined radiofrequency application in patients with lumbar facet joint disease , focusing on pain scores. The combined radiofrequency application, a sequence of pulsed radiofrequency and conventional radiofrequency , has been shown to be successful in treating neck pain and headache. These findings are of significant importance in the field of pain management and spinal disorders.
Detailed description
The treatment of chronic pain using pulsed radiofrequency (RF) has not shown any significant side effects. As a result, a combined approach of using both pulsed and conventional RF treatment in the same session has been assumed since the 2010s. This combined RF method is still widely used for pain management. The aim of this study is to compare the effectiveness of conventional RF with the combined RF method as a medial branch RF method for the management of lumbar facet joint pain.The study involved patients who had undergone medial branch denervation for lumbar facet joint pain and had medical records available. This study was conducted retrospectively by examining the study data. Patients with missing data were excluded from the study. Patients underwent a fluoroscopy-guided selective medial branch nerve block using 2% lidocaine 0.5ml before treatment. After 30 minutes, they were asked if there was a 50% reduction in pain intensity.The conventional RF group consists of patients who received medial branch RF with a duration of 2 minutes, at 80̊ C temperature, and 7 Volts. In the combined RF group, treatment was initiated first with a conventional RF duration of 2 minutes at a temperature of 80̊ C at 7 Volts. Then, pulsed RF duration was applied for 6 minutes at a temperature of 42 C at 45 Volts, with a pulse frequency of 2 Hz and a width of 20 ms.After procedure In the outpatient clinic, experienced pain specialists recorded NRS (Numeric Rating Scale) and DN4 (Douleur Neuropathic 4 Questions) scores at the 6th and 12th-month follow-up appointments after the procedure.
Interventions
PROCEDUREConventional RF
The conventional RF group consists of patients who received medial branch RF with a duration of 2 minutes, at 80̊ C temperature, and 7 Volts.
PROCEDURECombined RF
In the combined RF group, treatment was initiated first with a conventional RF duration of 2 minutes at a temperature of 80̊ C at 7 Volts. Then, pulsed RF duration was applied for 6 minutes at a temperature of 42 C at 45 Volts, with a pulse frequency of 2 Hz and a width of 20 ms.
