Trans Arterial Embolization for Facet Arthropathy
This single-site, single-arm study evaluates the feasibility, safety, tolerability, and efficacy of trans-arterial embolization (TAE) using Embozene microparticles for treating facetogenic pain due to facet arthropathy (osteoarthritis of the facet joints) in the lumbar spine.
• Age 18-85
‣ Confirmed diagnosis of spinal facet arthropathy on MRI OR CT
⁃ Confirmed diagnosis of lumbosacral facetogenic pain based on diagnostic nerve blocks.
⁃ Failed medical management of pain.
• Back pain persistent for at least 6 months
∙ Pain worse than at least 6/10 on a visual analog pain scale
⁃ Failed at least one of either intra-articular injections of steroids/ anesthetics or neuro-ablative procedure.
⁃ Maximum of 2 spinal levels of facetogenic pain in the lumbar and sacral spine (i.e. L4-5 and L5-S1).
⁃ Modified Rankin Scale 0-2
