| Summary: | The objective of this study was to compare the clinical efficacy of transforaminal epidural injection of dexamethasone and triamcinolone in the management of chronic low back pain with or without radiculopathy due to herniated intervertebral disc. It was a prospective, randomized, single-blind study, conducted in eighty patients of either sex suffering from low back pain of more than 3 months duration due to herniated intervertebral disc. The patients were allocated into two groups to receive either injection dexamethasone 8 mg or injection triamcinolone acetonide 40 mg as 2 ml solution through transforaminal epidural route. Each patient underwent unilateral lumbar transforaminal epidural steroid injections (TFESIs) at one level only depending on predominant involvement of nerve root on magnetic resonance imaging computed tomography of the spine and consistent with a clinical presentation of patients. Patients in both the groups were assessed prior to epidural injection and at the 2nd, 6th, and 12th weeks following epidural injection for the intensity of pain using a numerical rating scale of 0–10 and requirement of analgesics on weekly basis. Any adverse event following epidural injection was also noted during the follow-up period of the study. Improvement in pain score was significantly better with transforaminal epidural injection of triamcinolone acetonide compared to dexamethasone, in patients with chronic low back pain due to herniated intervertebral disc. No major adverse event was reported during the follow-up period in patients of either group.
