Abstract
A variety of spinal pathologies can result in symptoms including low back and radicular pain. These different diagnostic etiologies have different natural histories and may have varying responses to treatment. Unfortunately, this is not often accounted for in the literature, and the outcomes from treatment of these various diseases are lumped together based on their symptomology. This is an inappropriate way to examine the literature given the different pathologies. This article will therefore offer a narrative review of the outcomes of injection therapy for common disease processes including zygapophyseal (facet) joint pain, sacroiliac joint pain, discogenic pain, disk herniation with radicular pain, and spinal stenosis.
