Would you send a child with scoliosis to the chiropractor vs ortho specialist?

Absolutely Not. A child with a true scoliosis will not be helped by a chiropracter.The trained orthopedist is the better choice for safety and therapy.
Never to chiro. Chiropractic has nothing to offer children, and the strenuous deep thrusting they perform can be extremely dangerous. Your pediatrician can help you find an orthopedic specialist who can diagnose and deal with scoliosis properly.
