The aim of the procedure is to reduce pain by injecting local anesthetic andor corticosteroid around the affected nerve root. Despite its widespread use around the world, there is still limited evidence on the efficacy of lumbar SNRB in Vietnam. Patients and Methods: In this study, we conducted a retrospective study on 98 patients to evaluate the efficacy of lumbar SNRB in treating low back pain and radiculopathy.

Results: We report a significant improvement in mean VAS leg score from 8,2 ± 1,73 to 2,08 ± 2,02 in 88 cases after SNRB. Mean VAS leg score at 6 months is 3,56 ± 2,93 (p
