However, it poses a risk of inadvertent intradiscal, intravascular, and intrathecal injections.

Patients were categorized into two groups: Group A (ESI using the RdTF approach) and Group B (PEA using the Contra\u2010RdTF approach). Effective pain relief (EPR; \u226550% pain relief from baseline) in patients was evaluated using the visual analog scale (VAS) at 4 and 12\u00a0weeks after the procedure.
