Question 1

A Salter-Harris Type I fracture in a pediatric patient involves:

Accepted Answer

Transverse fracture through the physis (growth plate) only

Answer

Salter-Harris Type I fractures pass only through the hypertrophic zone of the physis; they may not be visible on X-ray but are diagnosed clinically by physis tenderness.

Question 2

Freiberg's infraction (osteochondrosis) most commonly affects which metatarsal head?

Accepted Answer

Second metatarsal

Answer

Freiberg's infraction involves avascular necrosis of a metatarsal head, with the second metatarsal (longest and most stressed) affected in approximately 68% of cases.

Question 3

The 'C-sign' on a lateral foot radiograph suggests which diagnosis?

Accepted Answer

Talocalcaneal coalition

Answer

The C-sign is formed by the outline of the talar dome and the sustentaculum tali creating a C-shaped arc on the lateral X-ray, indicating a talocalcaneal (middle facet) coalition.

Question 4

Congenital vertical talus (rocker-bottom foot) is pathologically characterized by:

Accepted Answer

Irreducible dorsal dislocation of the navicular on the talar head

Answer

Congenital vertical talus features an irreducible dorsal dislocation of the navicular onto the head/neck of the vertically oriented talus, producing the rigid rocker-bottom deformity.

Question 5

What is the most appropriate management for an asymptomatic, flexible pediatric flatfoot in a child aged 5 years?

Accepted Answer

Observation and parental reassurance

Answer

Asymptomatic flexible flatfoot in children is a normal developmental variant that requires only observation and reassurance, as intervention has not been shown to alter long-term outcomes.
