In this pilot study, investigators will test the efficacy of AlloGen-LI, an allograft derived
from amniotic fluid, injected into the epidural space at the level of spinal stenosis as an
anti-inflammatory treatment to relieve back and leg pain symptoms in patients with spinal
stenosis and/or disc herniation. The patients will be followed for 12 weeks. The effect of
this treatment will be examined by patient reported changes in pain and disability utilizing
validated outcome measures, and MRI imaging evaluating changes in contrast enhancement and T2
signal related to that reflect inflammation and degeneration.
