IntroductionThe treatment of persistent cervical radicular pain (CRP) by CT-guided epidural steroid injections (CTESI) by a transforaminal anterolateral (TFA) approach is associated with rare but serious complications. Two recently described transforaminal posterolateral (TFP) and transfacet indirect (TFT) approaches may be safer options, but have not been extensively evaluated. We compared the efficacy of three CTESI approaches (TFA, TFP, and TFT) in the treatment of persistent CRP (>6 weeks).MethodsPatients were prospectively assessed for pain using the visual analog scale (VAS) and for functional disability by the Neck Disability Index (NDI) before treatment, then 6 weeks and 6 months after CTESI.ResultsA total of 104 patients were included (n = 30 TFA, n = 36 TFP, and n = 38 TFT approaches). Each group was found to have a statistically significant improvement at 6 weeks (median VAS values: 7 (2-9) at D0 and 2 (3-6) at 6 weeks p < 0.01; median NDI values: 38 (24-50) at D0 and 29 (18-42) at 6 weeks (p < 0.01)), and at 6 months (median VAS values: 7 (2-9) at D0 and 4 (2-6) at 6 months (p < 0.01); median NDI values: 38 (24-50) at D0 and 28 (13-40) at 6 months (p < 0.01)). No significant difference was observed in the decrease in VAS and NDI scores among the three approaches at 6 weeks (p = 0.635 and p = 0.54 for VAS and NDI respectively) or 6 months (p = 0.704 and p = 0.315 for VAS and NDI respectively). No major complications were noted.ConclusionThe results of CTESI using the TFP or TFT approach are similar to those for TFA in the treatment of persistent CRP and could be a safer option.
