Objective. The aim of this study was to compare the accuracy and efficacy of sonographically guided lumbar periradicular injections through in-plane or out-of-plane approach techniques for patients with unilateral lower lumbar radicular pain. The feasibility and accuracy of these techniques were studied by means of computed tomography (CT). Methods. A total of 46 patients with chronic unilateral lumbar radicular pain were recruited and randomly assigned to either the in-plane or out-of-plane injection group. A mixture of 3mL 1% lidocaine and 7mg betamethasone was injected. Thevisual analog scale (VAS) was used to assess pain before and after treatment. Results. The pain intensity, asmeasured by VAS, significantly decreased in both in-plane and out-of-plane injection groups. Conclusions. The sonographically guided periradicular injections are feasible and effective in treating lumbar unilateral radicular pain.
