Scoliosis – What You Should be Aware of?
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.
June is a Scoliosis awareness month as declared by the US Scoliosis research society. Nowadays, there are many scoliosis care centers are available in the US.
Types of Scoliosis (Classification):
Scoliosis can be structural or non-structural
Non-structural: It is can be postural, compensatory or transient. Compensatory could be due to leg length discrepancy where the pelvis on the shorter side may dip lower. Transient could be due to sciatica (functional adaptation by one's body) or inflammatory (psoas abscess).

The good news about non-structural scoliosis is that it will straighten out with voluntary effort in non-weight bearing positions.
Structural: As a result of osseous and soft tissue changes, this curve becomes rigid. It can be of idiopathic(most common), neuromuscular, neurofibromatosis, congenital, mesenchymal or traumatic origin
The biomechanical changes in scoliosis are three dimensional. When looking from an aerial view, in a healthy person, we see the head, shoulder girdle and pelvic girdle all in one line. This orientation changes in a scoliosis person.
We see the shoulder and pelvic girdle rotate in one direction while the rib cage in another. This results in a clinical presentation of rib hump prominence of rib on one side.
The ribs on the side of the rib hump tend to approximate and this becomes the concave side of the scoliosis curve. The vertebral bodies with the spinous process and pedicles rotate on the convex side of the curve.
