Purpose
This study aimed to compare the clinical effectiveness and potential benefits of ultrasound (US)-guided versus fluoroscopy (FL)-guided cervical retrolaminar block (RLB) in patients with cervical facet joint pain.
Materials and Methods
A total of 27 patients aged 40 years or older who were diagnosed with cervical facet joint syndrome based on physical examination and imaging modalities were included. 12 patients of group I treated with US-guided RLB and 15 patients of group II treated with FL-guided RLB. The position of the needle and the distribution of contrast agent were confirmed using fluoroscopic images, and the changes in numeric rating scale (NRS) and neck disability index (NDI) before and 2 weeks after the procedure were compared in the two groups.
Results
Radiologically, the target agreement of needle placement in group I was 75%. There was no difference in contrast medium spread between the two groups. Clinically, the mean NRS improved from 7.08±0.52 to 3.08±0.90 in group I (p=0.01) and from 7.20±0.56 to 3.33±0.72 in group II (p=0.01). The mean NDI decreased from 41.67±2.27 before the procedure to 20.83±2.33 after the procedure in group I (p=0.01), and from 40.87±2.61 before the procedure to 21.67±2.02 after the procedure in group II (p=0.01), with no difference between the two groups.
Conclusions
US-guided cervical RLB is an effective, radiation-free alternative to FL-guided RLB for managing cervical facet joint pain, offering comparable pain relief and functional improvement.
