T2-T8 Vertebrae

vertebrae thoracicae II-VIII

Vertebrae T2 through T8 are the mid-thoracic vertebrae that articulate with the corresponding ribs at their costal facets, contributing to the thoracic kyphosis and providing attachment for the erector spinae and semispinalis muscles.

Anatomical Data

Structure & Landmarks

Articulations	Adjacent vertebrae above and below Bilateral rib heads and tubercles Bilateral facet joints
Landmarks	Long downward-directed spinous processes Costal facets on the body and transverse processes Relatively narrow spinal canal
Ossification	As per T1 vertebra pattern.

Clinical Relevance

Clinical Notes

The mid-thoracic vertebrae from T2 through T8 are the most rigidly supported part of the spine because of the rib cage and sternum. Fractures here from osteoporosis or trauma are less common than at the thoracolumbar junction but produce significant pain and deformity. The thoracic cord at these levels is at risk in epidural haematoma and abscess from the relatively small canal-to-cord ratio.

Pathology

Common Injuries & Conditions

Osteoporotic Compression Fracture

Mid-thoracic vertebral bodies commonly collapse anteriorly in osteoporosis after minimal trauma, producing back pain, height loss, and increasing kyphosis.

Scheuermann Kyphosis

Wedging of three or more adjacent thoracic vertebrae in adolescence produces a rigid, increased thoracic kyphosis with vertebral endplate irregularity.
