Background: Low back pain (LBP) is one of the most common causes of disability. Intradiscal RF appears to be a safe, minimally invasive treatment option for carefully selected patients with chronic discogenic LBP who have not responded to aggressive non-operative care. The aim of the present study was to investigate the efficacy and safety of percutaneous intradiscal radiofrequency (PRF) in patients with chronic disabling discogenic back pain. Patients and methods: This a prospective Cohort studywas carried out at Neurosurgery Department, Faculty of Medicine, Zagazig University and included patients with chronic LBP without radiculopathy or neural compromise in MRI. Full history taking, complete clinical evaluation, laboratory and radiological examination were performed preoperative and post-operative. Results: There is statistically significant decrease in mean CPK from 94.23 to 85.38 postoperatively.There is highly statistically significant decrease in OSI post-operatively. Median decreased from 35 to 15 four weeks postoperatively. There is highly statistically significant decrease in mean VAS from 6.31 to 4.38 postoperatively. There is highly statistically significant increase in time till sitting intolerance as median increased from 30 minutes to 75 minutes postoperatively. Final outcome showed improvement in both OSI and VAS and 10 patients had successful surgery. Conclusion: Intradiscal radiofrequency maneuver exhibited more effective than other techniques that previously used. Intradiscal RF appears to be a safe, minimally invasive treatment option for carefully selected patients with chronic discogenic LBP who have not responded to aggressive non-operative care.
