Aims: 1. Study the change in pain and function in patient with lumbosacral disc disease on MRI using visual analogue scale (VAS) and the revised Oswestry disability index (ODI) for back pain after administration of fluoroscopically guided transforaminal epidural injection. 2. Correlate the response of the patient with the spread of contrast in epidural space. Method: 100 patients with history of low back ache and imaging findings of disc herniation were enrolled based on inclusion criteria. Patients scored their pain on the VAS and functional disability on revised ODI. The patient was evaluated for distribution of pain and was administered a combination of anaesthetic and steroid after confirming the position of the tip of needle using iodinated contrast. Follow up for response to pain and improvement in disability in immediate post procedure done at 3 and 6 months. Result: 102 injections were administered for 100 patients which comprised of n=69 {67.6%} male and 33{32.4%} female and age distribution was 21-79 years. The distribution of indication was disc bulge n=29 (28.4%), extrusion n=12 (11.8%), post operative n=19 (18.6%), protrusion n=42 (41.2%). No significant difference between the VAS scores (p=0.20) of the individual indication pre procedure. After 3 & 6 months there was statistically significant difference between the mean rank value of population indicating maximum benefit for disc bulge population and least for post operative population at three months follow up. Conclusion: There is statistically proven good results in all cases for 6 months, after which repeat injections may be tried.
