The most effective way to determine the nature of your child’s curve is to have a pediatric orthopedic surgeon measure the Rib Verteral Angle Degree (RVAD). This simple, free and effective measuring technique uses a pencil and a ruler and was developed by Dr. Min Mehta in the early 70s.

If the RVAD is more than 20 degrees, the child’s scoliosis is considered to be PIS and progressive in nature. Immediate treatment with Mehta’s Growth Guidance Casting (MGGC) is indicated.

If the RVAD is under 20, it’s considered self-resolving and must be monitored closely with a follow up x-ray within 2 months.
