[Femur shaft fractures in infants should be considered despite no known trauma]

Area of Science:

• Pediatric Orthopedics
• Child Abuse Detection
• Radiology

Background:

• Femur shaft fractures in infants are uncommon injuries.
• These fractures are frequently linked to physical abuse or significant trauma like falls from heights.

Observation:

• Radiographic identification of infant femur fractures is typically straightforward.
• Clinical assessment requires attention to extremity pain signals and objective signs like thigh swelling and tightness.

Findings:

• While X-rays often reveal the fracture, determining the underlying cause can be challenging.
• Early detection is critical for improving patient outcomes and identifying potential child abuse.

Implications:

• Prompt recognition of femur fractures aids in prognosis and the detection of battered child syndrome.
• Thorough extremity injury evaluation is essential, even when no trauma history is provided.
