Outcome of transforaminal epidural steroid injection for lumbar radiculopathy: initial three-year experience at Upendra Devkota Memorial-National Institute of Neurological and Allied Sciences, Nepal.

Background: The prevalence of low back pain with radiculopathy in general population varies from 9.9% to 25%, which can be due to bony narrowing of the lateral recess or due to prolapsed intervertebral disc. Transforaminal epidural injection of a mixture of long-acting anaesthetic (bupivacaine) and particulate steroids (depomedrol) has been a treatment modality in patients not responding to initial physiotherapy and neuropathic pain medications.
