The word scoliosis in Greek means crooked, referring to the S or C shaped presentation of the spine. The incidence of scoliosis is more in females than in males (ratio of 5:1).
June is the month of Scoliosis awareness as stated by the US Scoliosis research community.
Types of Scoliosis:
Scoliosis can be structural or non-structural. If you want to know more about scoliosis, you can also check out this source: Scoliosis Surgery in Singapore & Scoliosis Treatments at Hiyh.info.
Non-structural: Can be postural, compensation or temporary. Compensation can be caused by differences in leg length where the pelvis on the shorter side can drop lower. Transient can be caused by sciatica (functional adaptation by one's body) or inflammation (psoas abscess).

The good news about non-structural scoliosis is that it will be straightened out by voluntary efforts in a bearingless position.
Structural: As a result of changes in the osseous and soft tissues, this curve becomes rigid. This can be from idiopathic (most common), neuromuscular, neurofibromatosis, congenital, mesenchymal or traumatic origin
Biomechanical changes in scoliosis are three dimensions. As Katherine Schroth explained, here are the elements involved:
When looking at it from an aerial perspective, in a healthy person, we see the head, shoulders and hip belt all in one row. This orientation changes in scoliosis people.
We see the shoulder and pelvis rotating in one direction while the ribs in the other. This results in a clinical presentation of protruding ribs on one side.
The ribs on the side of the hump tend to approach and this becomes the concave side of the scoliosis curve. The vertebral body with spinous and pedicle processes rotates on the convex side of the curve.
