Among toddlers and children up to age five, femur fractures usually result from a low energy fall. In most cases, the orthopedic surgeon realigns the fractureusing fluoroscopy or x-ray imaging as a guide and immobilizes the leg in a type of cast called a spica cast. Approximately how many weeks does it take for a fractured femur to heal in a 3-year-old?

Correct Answer: C

Rationale: In general, it takes approximately 6 to 8 weeks for a fractured femur in a 3-year-old child to heal. Children tend to heal faster than adults due to their higher metabolism and more robust bone growth. The spica cast helps stabilize the fracture and provides the necessary support for proper healing. Regular monitoring through x-ray imaging ensures the healing progress and guides the decision for cast removal.
