Question 1

What is the primary indication for prescribing a Supramalleolar Orthosis (SMO) in a pediatric patient?

Accepted Answer

Providing medial-lateral ankle stability for children with hypotonia

Answer

SMOs are designed to provide medial-lateral stability at the subtalar joint and are commonly prescribed for hypotonic children who exhibit excessive pronation and instability.

Question 2

At approximately what age does the longitudinal arch of the foot typically become fully established in children?

Accepted Answer

3 to 8 years

Answer

The longitudinal arch is obscured by a fat pad in infants and begins to develop as the child walks; it is typically fully visible and established between ages 3 and 8.

Question 3

Which orthosis is the standard of care for maintaining correction in a child with idiopathic clubfoot (talipes equinovarus) after completing the Ponseti serial casting protocol?

Accepted Answer

Ponseti foot abduction brace (Dennis Browne bar)

Answer

The Ponseti foot abduction brace (Denis Browne bar with open-toe shoes) is the proven device used after casting to maintain clubfoot correction and prevent relapse.

Question 4

How frequently should growth and fit be reassessed when a pediatric patient is wearing a custom AFO?

Accepted Answer

Every 3 to 6 months

Answer

Rapid skeletal growth in children necessitates reassessment every 3 to 6 months to ensure the orthosis still fits correctly and has not become restrictive.

Question 5

A Dynamic Ankle-Foot Orthosis (DAFO) differs from a solid AFO primarily in that it:

Accepted Answer

Provides total-contact support while allowing controlled range of motion

Answer

DAFOs are designed with thin, flexible trim lines that provide full plantar contact and proprioceptive input while permitting controlled, functional ankle motion.
