At what age do we typically see AIS?

• A. Under 5 years
• B. 5 to 10 years
• C. 15 to 20 years
• D. Over 10 years

Answer: (D)

AIS comes on during the teenage years, around puberty, when growth spurts happen. This is when the spine is most likely to start curving and the curve can progress as the child grows. Because of that timing, the best match among the options is the one describing onset after age 10—adolescence is typically after 10 years old, and the condition most commonly first becomes noticeable in early to mid-teen years. The earlier age ranges fit infancy or early childhood scoliosis more than AIS, and while some teens can be older, the usual window to expect AIS is after 10.
