Thoracic spine deformity

The thoracic spine is kyphosis during the embryonic period and gradually becomes kyphosis after the child sits up. This change is called secondary curvature. The formation of secondary curvature is generally caused by the thickness of the vertebral body and the anterior disc after the weight. The existence of the thoracic spine physiological curvature can increase the elasticity of the thoracic spine, reduce and buffer the shock of gravity, and prevent damage to the spinal cord and brain. Due to long-term sitting, poor sleeping posture and dehydration of the nucleus pulposus of the intervertebral disc, the lordosis of the thoracic vertebra can gradually disappear, and it can even become straight or buckled, that is, kyphosis.
