Palm Bruising in Infants: A Recognizable Pattern of Abuse

Area of Science:

• Pediatric Medicine
• Forensic Medicine
• Child Abuse Recognition

Background:

• Infant bruising is a critical sentinel injury necessitating evaluation for child physical abuse.
• Forceful squeezing of an infant's hand can cause a specific bruising pattern on the palm.
• Benign explanations like self-inflicted injury are unlikely for this distinct bruising pattern.

Observation:

• Eleven infant cases with a unique palm bruising pattern are presented.
• A perpetrator's confession corroborates the mechanism of injury.
• This specific bruising pattern has not been previously documented in medical literature.

Findings:

• The distinct palm bruising pattern is strongly associated with child physical abuse.
• Concurrent occult injuries are common but not required for diagnosing abuse in these cases.
• Emergency physicians must recognize this pattern as indicative of abuse.

Implications:

• Early identification of this bruising pattern aids in diagnosing child physical abuse.
• Recognition can prevent further infant injury and potential fatalities.
• This finding is crucial for emergency physicians managing suspected child abuse cases.
