Kyphosis Total

**Kyphosis** is a curvature of the spine in the thoracic region with a convexity forward. In children and adolescents, kyphosis occurs when the back muscles are weak. For adults, the normal form is physiological kyphosis, formed by the convexities of the spine at the level of 4, 8, 12 thoracic vertebrae and an arched bend (lordosis) of the cervical and lumbar regions.

**Kyphosis (from the Greek kyphos - stooped)**

Kyphosis of the chest is an excessive curvature of the spine in the spinal column or central part of the patient's back. This can lead to rotation of the vertebrae, which usually occurs when the load in the form of pressure on the column begins to exceed its ability to support this load, this occurs due to the relative fragility of the spine either from birth or due to rapid growth or even due to postural disorders. Gravity increases friction between the vertebrae. The spine allows a load to pass through it with a gradual reduction in frictional and abrasion forces based on Poisson's ratio and the range of inclination.
