Clinical outcomes of transforaminal versus interlaminar epidural injection among patients with lumbosacral disc herniation

A clinical outcome of the Transforaminal Epidural Steroid Injection (TFESI) and Interlaminar Epidural Steroid Injection (ILESI) procedures in patients with lumbosacral disc herniation is of interest. Hence, a total of 60 patients were randomly allocated to be given TFESI (n=30) or ILESI (n=30). The two groups were both administered 8 mg dexamethasone and 0.5 ml of preservative-free lignocaine filled to the 1ml level. Visual Analog Scale (VAS) and the Numeric Rating Scale (NRS) are to be used to measure pain at the pre-intervention, 15 days of intervention, as well as 3 months post-intervention. Thus, we show that TFESI was effective with enhanced pain relief, especially at the three-month follow-up.
