High Voltage VS Standard Voltage Radiofrequency in a Patient With Failed Back Surgery Syndrome

Postoperative lumbar spine pain syndrome (FBSS) refers to patients who have undergone surgery for lumbar spine disease one or more times and still have intractable lumbosacral pain after surgery, with or without lower limb sensory and motor dysfunction. Pain is the main reason for reducing patients' quality of life. Hussain and Erdek believe that despite up to 3 months of postoperative intervention, pain may still exist. Since persistent pain seriously affects patients' daily life and work, optimizing the FBSS treatment plan and improving the quality of life of FBSS patients cannot be ignored. At present, the treatment methods for neuropathic pain radiated to the lower extremity after lumbar spine surgery mainly include oral drug therapy, nerve block, pulsed radio frequency (PRF) and spinal cord electrical stimulation, and other minimally invasive interventional methods. Still, there is no domestic or foreign treatment method is reported in the literature to be effective.
