Background

The spine is the pillar of the body, is located in the middle of the back, with the upper end connected to the skull and the lower end reaching the tip of the coccyx. The spine is divided into five sections of neck, chest, waist, sacrum and tail, the upper part is long and can move, and the spine is similar to a bracket and is hung on the chest wall and the abdominal wall; the lower part is short and is fixed. The weight of the body and the shocks received thereby are transmitted to the lower limbs. The spine is composed of vertebrae and intervertebral discs, and is a relatively flexible and mobile structure. The shape of the spine can vary considerably with the kinematic loading of the body. The movement of the spine depends on the integrity of the intervertebral discs and the harmony between the articular processes of the relevant vertebrae. The length of the spine, 3/4, is made up of vertebral bodies and 1/4 is made up of intervertebral discs.

In orthopedic medical treatment, the problem of kyphosis is critical, most of kyphosis are caused by long-term bad postures, so the kyphosis is also called postural kyphosis, the posture can be improved as long as the postural kyphosis is noticed by oneself, the postural kyphosis can be corrected before the age of 35, the younger the postural kyphosis is, the easier the correction is, and the better the effect is.
