Whereas some relationships were noted between MRI findings and the response to lumbar facet joint interventions, many of these correlations tended to be weak. However, this study does suggest the possibility that patients with spinal stenosis, often considered an exclusion criterion for facet interventions, may respond to RF denervation of facet joints. Prospective studies are needed to confirm these observations.
