| Abstract |
BACKGROUND
At present, epidural steroid injection is one of the most frequently used methods in the treatment for low back pain.. But this method is nonspecific and results in a widespread of injected agent around the target point.
Therefore we thought direct injection to the nerve root is more specific and effective.
METHODS
The authors evaluated the effects of lumbar paravertebral steroid injection in 39 patients with low back pain and radicular pain, retrospectively. We used triamcinolone 40mg(1ml) and 0.25% bupivacaine 3ml as injection agents and used pain relief scale(PRS) score for assessment of the effect.
RESULTS
One week after injection, the patients of PRS score less than 5 were 65% in spinal stenosis and 85% in herniated intervertebral disc(HIVD). The patients of effective response more than 4 weeks after injection were 48% in spinal stenosis and 68% in HIVD, more than 12 weeks were 22% and 38%, respectively. The patients of PRS score less than 5 were 45% at the time of follow-up study.
CONCLUSIONS
We think paravertebral steroid injection is effective in patients with low back pain and radicular pain.
Therefore, this technique could be alternative method to epidural steroid injection. |
