For Sciatica & spinal stenosis steroid epidurals are used but controversy exists over whether there is any benefit of particulate over soluble steroids. It would seem obvious that a steroid that last weeks would be better than one that last 6 hours. This study demonstrated just that.

Is there a difference in treatment outcomes between epidural injections with particulate versus non-particulate steroids?
Bensler S et al
- bit vague on what where their candidates but appeared to be usual indications of sciatica and spinal stenosis
- 40 mg triancinolone or 4 mg dexamethasone epidurally
- Use CT guidance and dye injection to ensure placement which would go along way to ensure proper – there is a septum in lumbar region and dye may not make it to where it is needed.

Using 40 mg appears that is all that is necessary:
Sciatica Back Epidural or Caudal – 40 mg Steroid as Good as 80 mg.
With such a small dose, this could be repeated every 6 weeks. Otherwise, in between,
one could use Midazolam shot – I give them caudally and they last over 1 month.
