Effect of pulsed radiofrequency on the lumbar dorsal root ganglion for the management of remnant

lumbar radicular pain in patients who had prior Lumbar Surgery

ailed Back Surgery Syndrome (FBSS) is almost exclusively

used to describe a patient who had have poor clinical

outcomes following of lumbar Spine Surgery. Radicular pain is

related to lesions that either directly compromise the Dorsal

Root Ganglion (DRG) or indirectly compromise the spinal

nerve and its roots by causing ischemia or inflammation of

the axons. Our study was to assess the amount of pain relief

after a singling Pulsed Radio Frequency (PRF) in patients with

Remnant Radiculopathy Prior Lumbar Surgery. A total of 31

patients underwent PRF on DRG for the treatment of Lumbar

Radicular Pain in patients with Prior Lumbar Surgery. Pain

intensity was assessed using a Numeric Rating Scale score

(NRS). The NRS scores were measured before treatment, and

1, 3, 6, and 12 months after treatment. Successful treatment

was defined as experiencing more than a 50% reduction in the

NRS score at 12 months, as compared with the pre-treatment

NRS. After PRF, the mean NRS decreased after treatment.

The pre-treatment NRS was 8.1 ± 0.7. The mean NRS were

5.9 ± 1.5, 5.8 ± 1.7, 5.7 ± 1.6, and 5.6 ± 1.7 at 1,3,6, and 12

months, respectively. Scores on the NRS was significantly

different over time (P=0.000). The percent frequency of a 50%

reduction of in the NRS was 16.1%, 22.7%, 25.8%, and 28.9%,

at 1 months, 3 months, 6 months, and 12 months, respectively.

There was no correlation between the post-operative duration

and pain relief. PRF appears to be considered for treatment

for patients who had remnant lumbar radicular pain.
