Objective: To investigate the effi cacy of ultrasonography (US)-guided injections in patients with low lumbar facet syndrome, compared with that in patients who received fl uoroscopy (FS)-guided injections.
Method: Fifty-seven subjects with facet syndrome of the lumbar spine of the L4-5 and L5-S1 levels were randomly divided into two groups to receive intraarticular injections into the facet joint. One group received FS-guided facet joint injections and the other group received US-guided facet joint injections. Treatment eff ectiveness was assessed using a visual analogue scale (VAS), physician’s and patient’s global assessment (PhyGA, PaGA), and the modifi ed Oswestry Disability Index (MODI). All parameters were evaluated four times: before injections, and at a week, a month, and three months after injections. We also measured, in both groups, how long it took to complete the whole procedure.
Results: Each group showed signifi cant improvement from the facet joint injections on the VAS, PhyGA, PaGA, and MODI (p<0.05). However at a week, a month, and three months after injections, no signifi cant diff erences were observed between the groups with regard to VAS, PhyGA, PaGA, and MODI (p>0.05). Statistically signifi cant diff erences in procedure time were observed between groups (FS: 248.7±6.5 sec; US: 263.4±5.9 sec; p=0.023).
Conclusion: US-guided injections in patients with lumbar facet syndrome are as eff ective as FS-guided injections for pain relief and improving activities of daily living.
