Thoracic facet joints are tiny joints at each section of the spine that impart stability and facilitate guide motion. The facet joints can turn out to be painful due to arthritis of the spine, a back injury or mechanical strain.
Thoracic spine injections are involved in the assessment and treatment of pain in the upper back, chest and rarely, the arm. Acute and chronic pain syndromes from the thoracic spine are much less common than with cervical and lumbar spine. This is valid both for the incidence and the intensity of the disease. Only 2% of the entire painful spinal syndromes influence the thoracic spine.
In the region of the thoracic spine, the vertebral canal is comparatively narrow and there is only a small epidural space between the spinal cord and the osseous surrounding, or the intervertebral disc. The narrowest position is located between TH4 and TH9.
