Randomized controlled studies compared constructs ending at cervical vertebrae or thoracic vertebrae are needed to confirm these results. • The tenth thoracic vertebra (T-10) usually has a complete, superiorly placed costal facet on each side of the vertebral body and costal articulations on the transverse processes. The first cervical vertebra (C1) is called the Atlas. The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves). It consists of twelve vertebrae, which are separated by fibrocartilaginous intervertebral discs. By Gali Dar and Israel Hershkovitz. Furthermore, the spinous process of the thoracic vertebrae is long and fairly thick while it is short and blunt in lumbar vertebrae. Vertebral foramen or spinal foramen ( foramen vertebrale) is a large opening in the centre of the bone that forms a passageway for the spinal cord. The bodies in the middle of the thoracic region are heart-shaped, and as broad in the antero-posterior as in the transverse direction.

Thoracic hyperkyphosis is a defect that is easy to see from the side (lateral view), occurs when the thoracic flexion curve is over 40°. As part of the bony thorax, the thoracic vertebrae help protect the internal viscera - such as the heart, lungs and oesophagus. The laminae and spines of these vertebrae project caudally to overlap with the subjacent vertebra. 2. It is the site of muscle attachment. The lumbar vertebrae are, in human anatomy, the five vertebrae between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
