Question 1

A 10-year-old presents with anterior knee pain that worsens with jumping and running, and tenderness over the tibial tuberosity. Which condition is most likely?

Accepted Answer

Osgood-Schlatter disease

Answer

Osgood-Schlatter disease causes traction apophysitis at the tibial tuberosity, presenting with tenderness and swelling at that site in active adolescents.

Question 2

When assessing an infant for developmental dysplasia of the hip (DDH), which clinical test involves abduction of the flexed hip to detect a dislocated femoral head relocating into the acetabulum?

Accepted Answer

Ortolani test

Answer

The Ortolani test involves abducting the flexed hip; a 'clunk' indicates reduction of a dislocated femoral head back into the acetabulum.

Question 3

A pediatric physical therapist evaluates a 13-year-old with scoliosis. Which Cobb angle measurement is typically the threshold for recommending bracing in a skeletally immature patient?

Accepted Answer

25–40 degrees

Answer

Bracing is generally recommended for curves between 25 and 40 degrees in skeletally immature patients to prevent progression.

Question 4

Which gait deviation is most characteristic of a child with bilateral hip flexion contractures?

Accepted Answer

Increased lumbar lordosis with anterior pelvic tilt

Answer

Bilateral hip flexion contractures cause the pelvis to tilt anteriorly and the lumbar spine to hyperextend to maintain an upright posture during gait.

Question 5

In a child diagnosed with Legg-Calvé-Perthes disease, which stage is characterized by revascularization and new bone formation in the femoral head?

Accepted Answer

Reossification stage

Answer

The reossification (healing) stage is when revascularization occurs and new bone replaces the necrotic femoral head tissue.
