Scoliosis

Definition

Scoliosis is an abnormal curving of the spine. Your spine is your backbone. It runs straight down your back. Everyone’s spine naturally curves a tiny bit. But people with scoliosis have a spine that curves too much. The spine might look like the letter “C” or “S.”


Alternative Names

Spinal curvature; Infantile scoliosis; Juvenile scoliosis


Causes, incidence, and risk factors

Most of the time, the cause of scoliosis is unknown. This is called idiopathic scoliosis. It is the most common type. It is grouped by age.

  • In children age 3 and younger, it is called infantile scoliosis.
  • In kids age 4 - 10, it is called juvenile scoliosis.
  • In older kids age 11 - 18, it is called adolescent scoliosis.

Scoliosis most often affects girls. Some people are just more likely to have curving of the spine. Curving generally gets worse during a growth spurt.

Other types of scoliosis are:

  • Congenital scoliosis: This type of scoliosis is present at birth. It occurs when the baby’s ribs or spine bones do not form properly.
  • Neuromuscular scoliosis: This type is caused by a nervous system problem that affects your muscles, such as cerebral palsy, muscular dystrophy, spina bifida, and polio.
