Scoliosis
A spinal condition with irregular curvature, often of unknown cause.
Hwhwh27 · CC BY-SA 4.0
The spine in scoliosis deviates from its normal alignment, featuring a curve that is both sideways and rotational, often appearing as an S or C shape.[1][2][3] When comparing genders, females tend to experience more severe spinal curvature than males, at a proportion of four to one.[4]

Key facts and history
Diagnosis is confirmed with X-rays, and the standard method for assessing curvature is measuring the Cobb angle.[5][6] For the majority of scoliosis cases, the reason is not known, though a mix of hereditary and external factors is thought to play a role.[5][3][7] The condition most commonly appears during the rapid growth phase that occurs just before puberty.[5][7] The choice of treatment is guided by the curve's size, its spinal location, its underlying cause, and the individual's age.[1]
For small curves, periodic observation is often sufficient, whereas larger or progressing curves may be addressed with bracing, targeted exercises, or surgical intervention.[8][9] Alfred Shands Jr., an American orthopaedic surgeon, found that 2% of his patients had scoliosis unrelated to any other disease, which he later called idiopathic scoliosis.[10] Evidence of scoliosis has not been observed in chimpanzees or gorillas, which points to a possible evolutionary origin for the condition in humans.[11]
What the cited sources add
The NIAMS overview states that scoliosis is a sideways curve of the spine, and in most children and teens the cause is idiopathic.[3] The Scoliosis Research Society reports that AIS affects children between ages 10 to 18 and is found in as many as 4 in 100 adolescents.[12] The same source states that approximately 30% of AIS patients have some family history of scoliosis, indicating a genetic connection.[12] The NIAMS document explains that girls are more likely than boys to have idiopathic scoliosis, and having a family member with it increases risk.[3]
The Genetics Home Reference adds that mild scoliosis generally does not cause pain, problems with movement, or difficulty breathing.[7] The Genetics Home Reference states that adolescent idiopathic scoliosis, the most frequent spinal abnormality in children, emerges during late childhood or adolescence.[7]
