Effectiveness of selective transforaminal nerve root injection of triamcinolone with ropivacaine for lumbar radicular leg pain

Abstract

Background: Selective Nerve Root Block using steroid is a proven technique for management of lumbar radiculopathy. The aim of the study was to determine the effectiveness of selective nerve root block in lumbar radiculopathy. Methods: A prospective observational study was conducted for duration of one year in patients diagnosed with lumbar radiculopathy. Patients with leg pain, positive straight leg raising test and single level disc prolapse were included in the study. The procedure was performed under fluoroscopic guidance and Visual Analogue Pain rating scale was used for assessment pre-injection, immediate post injection 1 month, 3months and 6 months post injection. Results: Total 30 patient with mean age of 37.7± 9.31 years were included in the study. In 18 patients, this pain reduction was obtained immediately and in a further 8 patients within 4 days. In 4 patients, the nerve root block did not show a sufficient pain reduction. Conclusions: Selective transforaminal Nerve Root Block in lumbar radiculopathy significantly reduces Visual Analogue Pain Score post injection.
