Which factor is a key sign that may indicate non-accidental trauma in a child?

• A. Injuries in unusual locations
• B. Single clean line of injury
• C. Rapid return to baseline after injury
• D. Normal history matching the injury

Answer: (A)

Injuries in unusual locations signal non-accidental trauma because most everyday accidents in children affect commonly exposed areas like elbows, knees, shins, or forearms. When injuries appear in places that are hard to reach or protect during normal play—such as the ears, the back, genitals, buttocks, or multiple sites with different healing stages—the pattern doesn’t fit typical accidental mechanisms. This mismatch between the injury location and what’s plausible for the reported activity is a strong red flag that prompts a careful assessment and appropriate safeguarding actions.

A single clean line of injury can be suspicious, but it isn’t as specific a marker on its own and could result from a variety of causes. Rapid resolution to baseline is common with minor injuries or prompt care and doesn’t by itself confirm abuse. A history that matches the injury isn’t foolproof either, because caregivers may unintentionally misreport or conceal the true mechanism.
