Medial branch blocks are a nerve blocks that are targeted at treating joint pain in the spine, also known as the facet joints. The Medial branch nerves are nerves that transmits pain from the joints in the spine to the spinal cord. These joints are classified as cervical, thoracic and lumbar facet joints. At Colorado Pain Care, we utilize these blocks to determine how much pain is associated with the joint itself. This is important to determine given that pain could also come from the muscle, tendon/ligaments, disc, or nerve root. In other words, these blocks help determine the exact etiology of pain so as to best target therapy. It has been shown that these blocks can be highly successful with a greater than 70% patients reporting significant improvement in pain.
