Abstract

OBJECTIVE
To compare the efficacy of epidural injection in accordance the distribution of dye in the epidural space for low back pain patient. METHOD: Twenty nine patients with herniated nucleus pulposus or spinal stenosis confirmed by the radiologic studies were treated with epidural injection of steroid. The patients were divided into two groups: 1) patients whose distribution of dye was in the posterior part of epidural space and 2) patients whose distribution of dye was in the anterior and posterior parts of epidural space. RESULTS: The efficacy of epidural injection was assessed using the visual analog scale (VAS) and straight leg raising test (SLR) on pre-treatment and post-treatment. The VAS and SLR change of pre-treatment and post-treatment in the first group was from 7.81 +/- 1.54 and 50.00 +/- 18.97 degrees to 4.45 +/- 2.16 and 75.00 +/- 17.61 degrees (p<0.05), respectively. The VAS and SLR change of pre- and post-treatment in the second group was from 7.72 +/- 1.56 and 43.33 +/- 15.28 degrees to 3.72 +/- 1.64 and 60.00 +/- 10.00 degrees (p<0.05), respectively. The VAS and SLR change between groups has no statistically significant difference (p>0.05). CONCLUSION: The different distribution of dye in epidural space had no significant difference in treating patients with low back pain.
