Our experience with pulsed radiofrequency of dorsal root ganglion (PRF DRG) in the treatment of lumbar radiculopathy

B.B. Pavlov, Ya.V. Fischenko


Background. Degenerative diseases of the lumbar spine and concomitant clinical and neurological manifestations are one of the most important problems of modern orthopedics. Conservative treatment of this pathology is effective in 60 % of patients. In other cases, the pain becomes chronic, which leads to disability. These facts stimulated the development of minimally invasive procedures that are sufficiently effective at low risk of potential complications. The most common of them is radiofrequency ablation. The purpose is to study the dynamics of pain and social adaptation in patients suffering from chronic lumbar radiculopathy with the use of pulsed radiofrequency of dorsal root ganglion in their treatment. Materials and methods. A retrospective study included 42 patients aged from 27 to 78 (49.7 ± 14.8) years who were treated at the Neuromed Clinic in Kyiv and the Institute of Traumatology and Orthopedics of the NAMS of Ukraine in 2016–2017. The examination included patients suffering from reactive lumbosacral radiculopathy due to degenerative-dystrophic lesions of the spine. Pain syndrome was assessed on a 10-point visual analogue scale (VAS) before manipulation, immediately after it, and in 6 months. Social adaptation in everyday life was objectified with the help of the Oswestry Low Back Pain Disability Questionnaire, or Oswestry Disability Index. Results. No complications were registered. Every single patient reported a decrease in pain. Before manipulation, most patients described their pain as “very strong” (VAS 7.14 ± 0.68), and after the procedure, the majority of them considered it as “average” (VAS 4.02 ± 0.81). A similar trend persisted six months after treatment (VAS 1.85 ± 0.78). Before manipulation, Oswestry Disability Index was 71.42 ± 6.83. Six months after the procedure, it was already 18.57 ± 7.83. Conclusions. Pulsed radiofrequency of dorsal root ganglion is a safe and effective method for treating chronic lumbar radiculopathy.
