Intervertebral Disk of Thoracic Vertebra T2 (T2–T3) (Discus intervertebralis T2–T3)
Educational content only — not medical advice.
Anatomy
The intervertebral disk between thoracic vertebrae T2 and T3 is a fibrocartilaginous joint supporting the thoracic kyphosis. Characterized by a relatively uniform thickness and reinforced laterally by the costovertebral joints and rib cage, it provides stability and load dissipation across the mid-trunk with limited rotation.
Clinical notes
Thoracic disc herniation at the T2–T3 level is rare due to the splinting effect of the rib cage; when it occurs, it may compress the spinal cord or exiting thoracic root, presenting with band-like intercostal chest wall pain or progressive myelopathy.
