Question 1

A 2-year-old child presents with a limp and inability to bear weight after falling from a couch. X-ray reveals a spiral fracture of the tibia with no signs of other injuries. What is the MOST likely diagnosis?

Accepted Answer

Toddler's fracture

Answer

A toddler's fracture is a spiral tibial fracture common in young ambulatory children resulting from low-energy torsional forces during normal activity.

Question 2

Which clinical finding is MOST consistent with a diagnosis of slipped capital femoral epiphysis (SCFE) in an obese adolescent male?

Accepted Answer

Obligate external rotation of the hip with flexion

Answer

In SCFE, the femoral head slips posteriorly and medially; as the hip is flexed, the leg externally rotates obligatorily due to the altered head-neck relationship.

Question 3

In evaluating a child with juvenile idiopathic arthritis (JIA), which type is most associated with the development of uveitis and requires regular ophthalmologic screening?

Accepted Answer

Oligoarticular JIA

Answer

Oligoarticular JIA carries the highest risk of asymptomatic uveitis, especially in ANA-positive females, requiring regular slit-lamp ophthalmologic examination.

Question 4

A pediatric patient with osteogenesis imperfecta (OI) is referred for physical therapy. Which intervention is MOST appropriate to improve bone density and function while minimizing fracture risk?

Accepted Answer

Low-impact aerobic exercise and aquatic therapy

Answer

Low-impact aerobic exercise and aquatic therapy improve bone density and muscle strength while minimizing the mechanical stress that could cause fractures in OI.

Question 5

Which clinical sign indicates tibial torsion is present in a child, as measured during a prone physical therapy examination?

Accepted Answer

Thigh-foot angle outside the normal range of 0–30 degrees external rotation

Answer

The thigh-foot angle measures tibial torsion; values outside 0–30 degrees external rotation indicate abnormal internal or external tibial torsion.
