Abstract: Objective To observe the clinical efficacy of selective cervical nerve block combined with myofascial trigger point inactivation in the treatment of cervical spondylotic radiculopathy （CSR）. Methods Sixty CRS patients visiting the pain clinic at Songjiang District Sijing Hospital between March and September 2023 were randomly divided into three groups by random number table method, with 20 cases in each group. The treatment group （group A） received selective cervical nerve root and posteromedial branch block combined with myofascial trigger point inactivation treatment, the control group 1 （group B） received selective cervical nerve root and posteromedial branch block alone, and the control group 2 （group C） was treated with cervical traction and drugs. The patients were followed up at 1, 4, and 12 weeks after treatment for efficacy evaluation. The visual analogue scale （VAS） scores of neck and upper limb and the neck disability index （NDI） were compared across three groups. Results （1）Intra-group comparison revealed significant decreases in the VAS and NDI scores 1, 4, and 12 weeks after treatment in all groups （P<0.01）. （2） Pairwise comparison revealed that group A and group B consistently showed significantly lower VAS and NDI scores than group C at selected post-treatment time points （P<0.05）. Notably, group A exhibited significantly lower VAS and NDI scores than group B at the 12th week （P<0.05）, indicating a superior long-term effect. Conclusion The combined approach of myofascial trigger point inactivation and selective cervical nerve block for treating CRS demonstrates a synergistic effect, characterized by both rapid and sustained efficacy.
