Abstract :
Background: Prolapsed Intervertebral Disc (PID) was considered to be the commonest cause of sciatica
among many others. Though the presentation of sciatica was paradoxical, in which, some people
experienced sciatica without any disc prolapse on MRI/CT, whereas some people showed a prolapsed
disc without experiencing any of the symptoms related to sciatica. This gave rise to different
explanations that a disc prolapse in itself , is not enough to cause sciatica, and there might be some local
chemical agents that might be the causative factor due to their insulting attitude on the nerve roots.
Objectives: To study the functional outcome of patients with Posterior Lumbar Intervertebral disc
prolapse (PLIVDP), Lumbar Canal Stenosis, and Lumbar radiculopathy after Selective Nerve Root
Block at the corresponding level. Materials and Methods: A prospective cohort study on the functional
outcome of patients with lumbar radiculopathy with Intervertebral disc prolapse or lumbar canal
stenosis. Outcome measures used in this study are Owestry disability index score and Numerical rating
scale. All patients had taken an MRI scan, which was classified according to the Michigan state
university classification. After initial check up, pre-anaesthetic check up, selected patients were given
Selective Nerve Root Block with Methyl Prednisolone and local anaesthetic Bupivacaine. Patients were
scored at Immediate post Op, 3 weeks and 3 months after the injection was given and the data was
collected. Results: A total of 127 patients were given Selective Nerve Root Block in the study period.
Patients that were aged from 20-80 years were included. Average pre-injection ODI scores (in percent)
were 75.24, at 1 month 20.52 and at 4 months 19.86, with a p value of
