BACKGROUND: Sufferers with lumbosacral radicular ache might complain of persisting ache after monopolar pulsed radiofrequency (PRF) therapy.
OBJECTIVE: We evaluated the impact of bipolar PRF stimulation of the dorsal root ganglion (DRG) in sufferers with continual lumbosacral radicular ache who have been unresponsive to each monopolar PRF stimulation of the DRG and transforaminal epidural steroid injection (TFESI).
STUDY DESIGN: This can be a potential observational examine.
SETTING: The outpatient clinic of a single educational medical middle in Korea.
METHODS: We retrospectively reviewed knowledge from 102 sufferers who had acquired monopolar PRF to the DRG for administration of lumbosacral radiculopathy. Of those, 32 sufferers had persistent radicular ache that was scored at the very least 5 on a numeric score scale (NRS). Twenty-three of them have been included on this examine and underwent bipolar PRF of the DRG. The outcomes after the process have been evaluated utilizing the NRS for radicular ache earlier than therapy and 1, 2, and three months after therapy. Profitable ache reduction was outlined as >/= 50% discount within the NRS rating in contrast with the rating previous to therapy. Moreover, at three months after therapy, affected person satisfaction ranges have been examined. Sufferers reporting superb (rating = 7) or good outcomes (rating = 6) have been thought-about to be glad with the process.
RESULTS: The NRS scores modified considerably over time. At 1, 2, and three months after bipolar PRF, the NRS scores have been considerably diminished in contrast with the scores earlier than the therapy. Twelve (52.2%) of the 23 sufferers reported profitable ache reduction and have been glad with therapy outcomes three months after bipolar PRF. No critical adversarial results have been recorded.
LIMITATIONS: A small variety of sufferers have been recruited and we didn’t carry out long-term follow-up.
CONCLUSION: We imagine the usage of bipolar PRF of the DRG will be an efficient and secure interventional method for continual refractory lumbosacral radiculopathy. It seems to be a possible possibility that may be tried earlier than continuing to spinal surgical procedure.
