Brief summary
The study is conducted to compare pain relief, accuracy and safety and radiation exposure of selective lumbar nerve root injection for lumbar radicular pain using ultrasound guidance versus fluoroscopy guidance
Detailed description
Radicular pain is believed to be induced by irritation or inflammation of a nerve root caused by mechanical pressure or chemical irritation from degeneration herniation or rupture of intervertebral disc .Nerve root steroid injection is the most commonly performed minimally invasive technique for treatment of radicular pain in lumbar spine.The mechanism of action of steroids is to reduce inflammation by reduction in proinflammatory mediators around the nerve root, causing reduction in pain levels . Although Fluoroscopy guided technique is the most widely accepted method in lumbar selective nerve root injection, but recently ultrasound technique has gained acceptance among physicians due its reliability, efficacy, real-time guidance of injection and reduction of radiation exposure. Real-time guidance of injection provided by ultrasonography allows for good identification of the spinous process and adjacent structures such as lamina, zygapophyseal articulations and transverse process allowing for safer and potentially equally effective injection technique. The patients are randomly allocated into two groups; one group will receive injection under fluoroscopy guidance and the other group will receive injection under ultrasound guidance. The two groups are compared in terms of pain relief, accuracy and safety and radiation exposure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| improvement of visual analogue score of pain | 3 months | evaluation of pain relief using visual analogue score on a scale from 0 to 10 with higher scores mean worse outcome |
| improvement of Oswestry disability index score for back pain | 3 months | evaluation of pain relief using Oswestry disability index score on a scale from 0% to 100% with the higher scores mean worse outcome. |
Secondary
| Measure | Time frame | Description |
