OBJECTIVES: Retrodiscal transforaminal (RdTF) epidural steroid injection (ESI) is clinically comparable to conventional transforaminal ESI and can avoid catastrophic complications. However, it poses a risk of inadvertent intradiscal, intravascular, and intrathecal injections. Therefore, we aimed to evaluate the feasibility of percutaneous epidural adhesiolysis (PEA) using the contralateral (Contra)-RdTF approach. METHODS: The electronic medical records of 332 patients with unilateral lumbar radiculopathy due to foraminal disk pathology were reviewed. Patients were categorized into two groups: Group A (ESI using the RdTF approach) and Group B (PEA using the Contra-RdTF approach). Effective pain relief (EPR; ≥50% pain relief from baseline) in patients was evaluated using the visual analog scale (VAS) at 4 and 12 weeks after the procedure. The presence of unintended fluoroscopic findings and complications was recorded. RESULTS: A total of 119 patients were enrolled in the final analysis: 81 in Group A and 38 in Group B. Both groups showed lesser VAS scores after 4 and 12 weeks than at baseline (p < 0.05). However, the proportion of patients with EPR was significantly greater in Group B after 12 weeks (p = 0.015). No complications, including intrathecal injection, infectious discitis, and neurologic deterioration, were reported. However, inadvertent intradiscal and intravascular injections were reported to be significantly higher in Group A than in Group B (14.8% and 0%, respectively; p = 0.009). CONCLUSIONS: Although applications of this study are limited by its retrospective design, the results suggest that PEA using the Contra-RdTF approach is feasible because it can achieve EPR and avoid unintended fluoroscopic findings.
