Spinal deformities in adults can have a significant impact on their quality of life. Most often it occurs as a consequence of untreated or inadequately treated adolescent idiopathic scoliosis. Patients with adult scoliosis have a different clinical and radiological picture compared to patients with adolescent idiopathic scoliosis. Differences include degenerative changes within the curve, a natural history of deformity progression, and clinical symptoms.

The type of idiopathic scoliosis that occurs between 4 and 9 years of age is called juvenile scoliosis. The time period when juvenile scoliosis occurs is characterized by a much slower growth and development of the child, and thus a much slower progression of the scoliotic curve. Juvenile scoliosis is also the rarest type of scoliosis. The fact is that boys mature skeletally later than girls, and in them juvenile scoliosis occurs a little earlier, about 5 years, while in girls it is diagnosed about 7 years.

Idiopathic type of scoliosis that occurs in early childhood, it is necessary to clarify the division according to the age when scoliosis occur. Infantile, occures between 0-3 years of age. The period when infantile scoliosis occurs is usually a period of rapid growth and development, which means that in this period there is a big chance that there will be a significant worsening of the scoliotic curve.

Scoliosis was recognized at the 5th century BC, when Hippocrates described it, and also treatment for scoliosis. At the end of the 20th century, Katharina Schroth developed a three-dimensional treatment for the correction of scoliosis. From 1921, a new form of non-operative treatment of scoliosis began, which consisted of specific postural corrections, a corrective breathing pattern and correction of postural perception.

The most frequently noted long-term sequlae of untreated AIS are curve progression, back pain, cardiopulmonary problems and psyhosocial cocerns.
