What medical terminology should I use to describe and document the physical injuries (e.g., bruises, patterned contusions, abrasions, burns, bite marks, fractures) and behavioral signs of possible child abuse in my children, and how should I report this evidence to authorities?

Medical Documentation and Reporting of Suspected Child Physical Abuse

You should immediately document these injuries using precise medical terminology and report your concerns to child protective services (CPS) and law enforcement without delay, as any injury pattern inconsistent with the provided history or suggesting inflicted trauma mandates reporting. 1

Critical Medical Terminology for Physical Injuries

Skin and Soft Tissue Injuries

• Ecchymoses (bruises): Document the exact color (red, purple, brown, yellow-green), size in centimeters, shape (round, linear, looped, patterned), and precise anatomical location 1, 2
• Patterned contusions: Describe linear, looped, or parallel marks that suggest cord-whip injuries or implement use 1
• Tramline bruises: Parallel linear bruises from blows with stick-like objects 2
• Grab marks: Clustered oval or fingertip-shaped bruises, typically on upper arms, chest, or extremities 3
• Squeeze marks: Bruising along flexural folds forming negative imprints of the hand 3
• Bite marks: Rounded or horseshoe-shaped injuries with characteristic tooth pattern 4, 2
• Abrasions: Superficial skin scrapes—document location and pattern 4

Thermal Injuries

• Immersion burns: Symmetrical burns with sharp demarcation lines, often on buttocks, genitals, or extremities in a "stocking-glove" distribution 2
• Contact burns: Patterned burns matching specific objects (cigarettes, irons, heating grates) 4
• Splash burns: Irregular patterns with tapered edges (more consistent with accidental injury unless pattern suggests otherwise) 2

Fractures (If Suspected)

• Classic metaphyseal lesions (CMLs): Corner or bucket-handle fractures at bone ends, highly specific for abuse in infants 5
• Rib fractures: Especially posteromedial ribs—95% positive predictive value for abuse in children under 3 years 5
• Multiple fractures: Particularly bilateral or of different ages/healing stages 5
• Spiral fractures: Long bone fractures from twisting forces in non-ambulatory children 5

Documentation Protocol

Essential Elements to Record

• Photographic evidence: Take clear photos with a ruler for scale, showing each injury from multiple angles 1
• Anatomical mapping: Use body diagrams to mark every injury location precisely 1
• Injury count: Total number of injuries and whether clustered or distributed across multiple body regions 1
• Measurements: Length and width in centimeters for each lesion 1
• Color documentation: Exact color helps with injury dating, though color alone is unreliable for precise timing 1, 2
• Pattern description: Linear, looped, parallel, clustered (three or more in same region), or implement-shaped 1, 2
• Developmental history: Child's motor capabilities to assess whether reported mechanism is plausible for their age 1
• History inconsistencies: Document any changing explanations, delayed care-seeking, or implausible mechanisms 5, 2

Red Flags That Mandate Reporting

• Injuries inconsistent with history provided 1
• Multiple injuries of different ages (indicating repeated abuse) 5, 1
• Injuries inconsistent with child's developmental capabilities (e.g., fractures in non-mobile infants) 5, 1
• Delayed presentation for medical care 5, 2
• Changing or contradictory explanations 2
• High-specificity injury patterns: rib fractures, CMLs, cord-whip marks, immersion burns, bite marks 5, 1

Immediate Reporting Requirements

Report to CPS and law enforcement when any of the above red flags are present—you are legally mandated to report suspected abuse, and the threshold is "reasonable suspicion," not proof. 1, 6, 4

Who to Contact

• Child Protective Services: Your state/local CPS hotline (immediate phone report required)
• Law enforcement: For acute injuries or ongoing danger
• Hospital social work: If presenting to emergency department or clinic with social services

What to Report

• State your concern clearly: "I am reporting suspected child physical abuse"
• Provide child's identifying information, location, and immediate safety concerns
• Describe injuries using the medical terminology above
• Share your photographic documentation with authorities
• Note any statements the child made about how injuries occurred
• Document any concerning caregiver behaviors or explanations

Additional Medical Evaluation

If the child is under 24 months with any concerning injury, obtain a complete skeletal survey to identify occult fractures, which are present in 11-20% of abuse cases even when not clinically suspected. 1

For young infants with concerning injuries, obtain non-contrast head CT even if neurologically asymptomatic, as occult intracranial injury occurs in approximately 29% of such cases. 1

Critical Pitfall to Avoid

Do not delay reporting while seeking "more evidence" or trying to confirm abuse yourself—your role is to recognize concerning patterns and report, not to investigate or prove abuse. 6, 4 Approximately 80% of abusive fractures occur in children under 18 months, and many children with severe injuries had previously presented with less severe injuries that were overlooked 5, 6. Early reporting protects children from escalating harm.
