Q

What developmental events are indicated in the formation of the adult lumbar curve?

A
  1. Crawling will cause the abdomen to put tension on the lumbar region and pulls it forward
  2. Muscle development is promoted to compensate for the the swayback of the lumbars
  3. Intervertebral disc height will become greater anterior compared to posterior
  4. Walking will further promote muscle and intervertebral disc development

66
Q

What is the genetic factor associated with adolescent idiopathic scoliosis?

A

An autosomal dominant factor that runs in families

67
Q

What is the relationship between curve deviation, incidence, and curve worsening?
