Abstract

Cervical disc herniation causes nerve root compression, leading to pain and neurological dysfunction. Selective nerve root block injection helps reduce inflammation and perineural edema, thereby decreasing nerve root compression pressure and alleviating pain. This clinical interventional, longitudinal follow-up design study was conducted on 112 patients who underwent selective nerve root block injections. Data was processed using SPSS 25.0 software. The change in VAS score over time (before treatment, after treatment 1 day, 3 days, 7 days, 1 month, 3 months, 1 year) is as follows: VAS score decreased from 6.8 → 4.6 → 4.4 → 4.2 → 4 → 3.6 → 3.5. The improvement in pain score (reduction of more than 50%) in patients under 40 years old and patients with disease duration under 3 months is statistically higher than the other 2 groups. Unwanted effects of selective nerve root block injections are rare, mainly mild pain and swelling at the injection site.
