Percutaneous Radiofrequency Disc Decompression: A Study of 27 Patients

Abstract

Background: Percutaneous radiofrequency nucleoplasty is a true minimally invasive technique for treatment for radiculopathy caused by contained disc protrusions. This minimally invasive procedure uses controlled thermoablation for reducing the intervertebral disc and decompressing the lumbar nerve root. Material and Methods: Our study is a prospective analysis of 27 patients aged from 30 to 64 years with lumbar disc protrusion who were treated with percutaneous radiofrequency disc decompression (PRFD) between May 2018 and May 2019. Clinical follow-up was reported at 1 month, 3 months, and 6 months. The outcomes were assessed using a visual analog scale (VAS) and MacNab score. Results: Of the 27 patients, 14 were female and 13 were male. Their mean age was 53 ± 2 years. In all 27 patients, percutaneous radiofrequency nucleotomy was performed. An excellent outcome as reflected by MacNab score was observed in 17 patients (63%), a good outcome in 8 patients (29.7%), and a poor outcome in 2 patients (7.3%). Prior to treatment, the average back and leg VAS scores were 7.95 and 7.82, respectively. At sixth month follow-up, the back and leg VAS scores were reduced to 3.17 and 3.04, respectively. Patients with a poor outcome developed early recurrent disc prolapse and required endoscopic discectomy. Conclusion: PRFD is a safe and effective treatment of contained disc protrusion. PRFD is a good alternative to surgery. These procedures significantly increase quality of life in patients with lumbar radiculopathy.
