Thoracic Facet and Medial Branch Blocks
Thoracic facet origin pain accounts for 34–48% of mid and upper back pain. Thoracic facet injections and medial branch blocks are diagnostic and therapeutic tools for such pathology. Established pain referral patterns and predictable anatomical location of thoracic medial branch nerves aid clinicians in diagnosis and treatment of facetogenic pain. While evidence for efficacy of intra-articular thoracic facet injections is extrapolated predominately from studies involving the cervical and lumbar spine, prospective randomized trials have established thoracic medial branch blocks as a means of achieving pain and functional improvement with minimal complication.
