Eligibility

Inclusion criteria

Inclusion criteria: Unilateral radicular symptoms in age group 30-70 with VAS more than 5 not relieved with conservative treatment and physiotherapy after 3 weeks 2. Pain in one of the roots involving L2-L3, L3-L4, L4-L5 (Radiologically and clinically proven) 3. Patient requiring predominantly single root selective nerve root block injection. 4. Patient not having definite surgical indication as decided by neurosurgeon.

Design outcomes

Primary

Measure	Time frame
To compare the efficacy of needle placement in lumbar selective nerve root blockTimepoint: The efficacy will be seen as successful needle placement with decrease in visual assessment pain scores immediately, 24 hours,1 week and 2 weeks post procedure	—

Secondary

Measure	Time frame
To compare total time taken to correctly place the needle under USG and nerve stimulator versus C arm fluoroscopy guidance. To compare VAS scores between the two groups. To compare patient satisfaction scales scores between two groups. To compare quality of life index between two groups. Timepoint: Time taken will be measured after USG probe placement to appearance of decremental current in nerve stimulator in combination group.In gold standard group it will be measured after draping to successful dye infiltration VAS,Likert score will be ,measured 30 mins, 1 day, 1 week, 2 weeks post procedure QLI scale will be measured after 1 and 2 weeks post procedure	—
