Abstract

Objective: To evaluate the efficacy of cervical selective nerve root injection (CSNRI) under ultrasound-guided. Subject and method: From July 2021 to July 2022, a prospective study of 34 patients received ultrasound-guided CSNRI for cervical radicular pain C5-C7 at 108 Military Central Hospital. Patients are evaluated the complication after injection, the effect of procedure by the pain relief with Visual analogue scales (VAS) and the improvement of function of Neck Disability Index (NDI) before procedure and at 10 minutes, 2 weeks, 1 month and 3 months after procedure. Result: Our study on the US-guided CSNRI of 34 patients with 20 males and 14 females, the average age was 53.59 ± 8.67. The average VAS score was 8 ± 0.85 preoperatively and this improved to 2.03 ± 1.87; 2.59 ± 1.69; 1.79 ± 1.72 and 1.29 ± 1.29 at 10 minutes, 2 weeks, 1 and 3 months after procedure (p<0.001). The average NDI was 24.91 ± 7.64 preoperatively and this improved to 6.29 ± 5.87 and 4.35 ± 4.14 at 1 and 3 months after procedure (p<0.001). The successful rate of procedure with the decrease VAS more than 50% and the decrease of NDI more than 40% at 1 month and 3 months after procedure were 91.2% and 97.1% respectively. After procedure, there were 5 cases with mild complication (14,7%) with dizziness and nausea and 1 case with transient vasovagal. There was no serious complication. Conclusion: We suggest that ultrasound-guided CSNRI is an effective, safe, simple procedure and free of radiation and provides sustained pain relief in patients with cervical radiculopathy.
