prospective study of functional outcome of therapeutic and diagnostic selective nerve root block in management of patients with lumbar radiculopathy

Abstract

ABSTRACT Introduction: Lumbar radiculopathy or sciatica is pain radiating from the lumbar region to buttocks the leg or further down along the nerve dermatomal course. Selective nerve root block (SNRB) is used to treat radicular discomfort caused by a single damaged nerve root. Although it has a low diagnostic specificity, its therapeutic efficacy is still debatable. It's always used for those who have significant surgical spinal lesions, whether or not they have them. Other lesions that cause nerve root irritation include disc prolapse at various stages, ligamentum flavum enlargement, facet hypertrophy, and foraminal stenosis caused by degenerative osteophytes.
