عنوان انگلیسی The Effect of Gray Ramus Communicans Nerve Block on Radicular Pain in Patients With Lumbosacral Radicular Pain Who Underwent Transforaminal Epidural Block
چکیده انگلیسی مقاله Lumbosacral radicular pain (LRP) is usually caused by herniation of intervertebral discs and is characterized by pain arising in the back and radiating to the lower extremities. The current study evaluated the efficacy of gray ramus communicans nerve block (GRCNB) in decreasing LRP in patients with intervertebral disc herniation who underwent transforaminal epidural block. Thirty patients with magnetic resonance imaging indicating a disc herniation on the L4-L5 level participated in this study. All patients were randomly divided into two groups: one whose members underwent GRCNB (n=15) after transforaminal epidural block, and a second group (n=15) whose members underwent only transforaminal epidural block on L4-L5 on the affected side. Follow-up after the procedure ran for a period ranging from 6 to 10 months (mean=8.2±2.1 months) for radicular pain score and the need for analgesics. The mean age of the patients was 54.8±18.4 years (range: 30-65 years). LRP duration in all patients before the procedure was 6-24 months (mean: 12±10.9 months), and there was no significant difference between the two groups. A greater reduction in the numerical rating scale (NRS) one week, 1, and 6 months after the procedure was observed in the group with GRCNB compared to the other group. The reduction in need for analgesics one week, 1, and 6 months after the procedure was statistically significant in the group with GRCNB compared to the group without GRCNB. No major complications were observed in any of the patients in either group. GRCNB is effective in reducing radicular pain and the need for analgesics in patients with lumbosacral radicular pain.
