Abstract
Background: Failed back surgery syndrome (FBSS) affects an increasing number of patients. As lumbar surgery becomes more common, the incidence of FBSS is also expected to rise. This study aimed to compare the efficacy of high-voltage, long-duration pulsed radiofrequency (PRF) mode versus standard voltage PRF in treating radicular neuralgia following lumbar spine surgery.
Methods: Ninety patients, aged 20 to 60 years, both sexes, presented with FBSS without instrumentation. Patients were divided into two equal groups: Group I received standard low PRF treatment, while Group II received high-voltage long-term PRF.
Results: There was a significant decrease in the Oswestry Disability Index (ODI) and the Numerical Rating Scale (NRS) at 1 week, 1 month, and 6 months compared to pre-procedure values in both groups. Analgesic requirements after one week and six months were significantly higher in group I compared to group II (P >0.05).
Conclusions: High-voltage PRF is more effective than low PRF, resulting in enhanced quality of life for patients.
