These pathologies can be detected even in infants, although they are formed for a long time and become clearly visible at a later age.
According to statistics, every third person at least once in his life faced with such a phenomenon as a sharp back pain. And with every second, the cause of the pain remains unclear.
Scoliosis is a lateral deformity of the spine. It can be localized in different parts of the spine or in several at once, to have several forms of curvature.
Speaking about thoracic kyphosis, medical specialists mean the incorrect position of the corresponding vertebral part - namely, the wrong inclination of its anteroposterior plane.
Normally, each person has a fairly well pronounced lumbar lordosis. Represented by a bend in the opposite direction in the lumbar region. It acts as a shock absorber and protects the spinal cord from mechanical damage.
Any scoliosis is a spinal deformity, and S-shaped scoliosis is determined when, along with a frontal curvature resembling the letter C, there is a second lateral curvature — compensating, giving the spinal column the shape of the letter S.
According to the Scoliosis Research Society, juvenile scoliosis accounts for 12–25% of cases; girls are diagnosed more often than boys.
The spine takes on a pathological position most often in childhood or adolescence during the period of active development of cartilage and bone tissue, although such a defect can also occur in adults. The term scoliosis itself suggests that the curvature plane is frontal, in contrast to lordosis and kyphosis - bends in the sagittal plane.
In foreign literature, this disease is referred to as lumbar degenerative kyphosis (LDK), which is a subgroup of flat back syndrome.
