Sinuvertebral nerve block treats discogenic low back pain: a retrospective cohort study

Discogenic low back pain (DLBP) is considered the most common type of chronic low back pain (CLBP). Sinuvertebral nerve block (SVNB) is a rapid and precise intervention performed under local anesthesia to treat DLBP induced CLBP. Thus, in this study, we aimed to explore the clinical efficacy of SVNB for DLBP. We retrospectively included 32 DLBP patients from July 2020 and April 2021. Inclusion criteria: The patients had chronic pain, diagnosed as single-segment disc degeneration induced DLBP, and suffered from one-year ineffective conservative treatment. SVNB was performed and the patients were followed up at 3 and 7 days, and at 1 and 3 months after SVNB. The basic clinical characteristics, including age and gender, were collected. The measurements of Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were assessed. The average age was 49.31±14.37 years, and females males was 20 (62.50%) 12 (37.50%). The preoperative VAS and ODI score were 5.75±1.41 and 32.59±21.56, respectively. The VAS score was reduced to 2.50±1.46, 2.63±1.60, 3.53±2.17, and 3.78±2.18 at 3 and 7 days, and 1 and 3 months after SVNB, respectively (P
