Transforaminal Epidural Steroid Injection is highly recommended for the treatment and diagnosis of radicular pain resulting from lumbar disc herniation. Two of the techniques suggested for performing TFESI are the antero-posterior approach and the oblique approach.The aim of our study was to compare both techniques regarding time to perform the procedure, pain relief and the incidence of complications and adverse events.We didn't find any difference between the two techniques regarding pain relief or the incidence of adverse events, the time needed to perform the oblique approach was shorter (9.7±2.1 min) than the antero-posterior approach (11.3±2.2 min), mainly due to the performer being more familiar with it rather than a true difference.
