Question 1

What hip flexion angle is typically maintained by a Pavlik harness during DDH treatment?

Accepted Answer

90 to 100 degrees

Answer

The Pavlik harness maintains approximately 90 to 100 degrees of hip flexion combined with abduction, which places the femoral head into the acetabulum and promotes socket development.

Question 2

Genu varum (bowlegs) observed in an otherwise healthy 18-month-old child is BEST characterized as:

Accepted Answer

A normal developmental variant that typically self-corrects by age 2 to 3

Answer

Mild genu varum is a normal finding in toddlers due to in-utero positioning and physiological bone remodeling; it generally resolves spontaneously by age 2 to 3 without orthotic intervention.

Question 3

Which spinal orthosis is MOST commonly prescribed for adolescent idiopathic scoliosis with a Cobb angle between 25 and 40 degrees in a skeletally immature patient?

Accepted Answer

Thoracolumbosacral orthosis (TLSO) such as the Boston or Rigo Chêneau brace

Answer

The TLSO (e.g., Boston brace or Rigo Chêneau) is the current standard of care for adolescent idiopathic scoliosis curves of 25 to 40 degrees, as it controls thoracic and lumbar curves effectively and is more cosmetically acceptable than the Milwaukee brace.

Question 4

The Milwaukee brace (CTLSO) is specifically indicated over a standard TLSO in pediatric scoliosis when:

Accepted Answer

The curve apex is at or above T6 (high thoracic or cervicothoracic region)

Answer

The Milwaukee brace's cervical ring and superstructure allow it to address high thoracic and cervicothoracic curves whose apex is above T6, where a TLSO cannot reach.

Question 5

In a child with spastic diplegic cerebral palsy, the PRIMARY goal of AFO prescription is to:

Accepted Answer

Improve functional mobility, gait efficiency, and energy expenditure

Answer

AFOs for children with cerebral palsy are prescribed to normalize gait kinematics, reduce energy expenditure, and maximize functional independence in mobility.
