Insights
Distinguishing accidental from suspected inflicted extremity injuries in children after a reported fall is challenging. Bruising, displaced fractures, and multiple injuries were more common in suspected inflicted cases, indicating potential risk factors.
Area of Science:
- Pediatric Orthopedics
- Child Abuse and Neglect
- Forensic Pediatrics
Background:
- Distinguishing accidental falls from suspected inflicted injuries in pediatric extremity trauma is a significant clinical challenge.
- Caregiver-reported falls from caregiver hold are common presentations requiring careful evaluation.
Purpose of the Study:
- To analyze clinical and radiographic injury patterns associated with clinician-suspected inflicted versus accidental injuries in children presenting after a reported fall.
- To identify potential risk indicators for suspected inflicted injuries in this vulnerable population.
Main Methods:
- A single-center cross-sectional study of children under 12 years presenting with extremity injuries after a reported fall.
- Classification of cases as clinician-suspected inflicted or accidental based on medico-legal assessment.
- Analysis of injury patterns using chi-square/Fisher's exact tests, Mann-Whitney U test, and logistic regression models.
Main Results:
- Of 58 children, 31% were classified as clinician-suspected inflicted. Suspected inflicted cases were older and more likely to have the father as the caregiver.
- Bruising, displaced fractures, and multiple injuries/fractures were significantly more frequent in suspected inflicted cases.
- A combined pattern of bruising plus displaced fracture was observed in 66.7% of suspected inflicted cases versus 0% of accidental cases.
Conclusions:
- Specific clinical and radiographic patterns (bruising, displaced fractures, multiple injuries) are associated with clinician-suspected inflicted classification after a reported fall.
- These findings serve as risk indicators for early safeguarding triage and documentation, not definitive proof of abuse.
- Potential biases, including incorporation bias and misclassification, necessitate cautious interpretation and external validation.
Abstract:
Caregiver-reported drop/fall from caregiver hold is a common history in children presenting with extremity injuries, but distinguishing accidental injury from clinician-suspected inflicted injury remains challenging. This study examined clinical and radiographic injury patterns associated with clinician classification as suspected inflicted versus accidental at the index presentation. This single-center cross-sectional study included consecutive children younger than 12 years presenting to the orthopedic emergency room after a reported drop/fall from caregiver hold between 16 June and 31 December 2025. Cases were classified at presentation as clinician-suspected inflicted drop/fall or accidental drop/fall based on structured medico-legal assessment. Injury-pattern variables were analyzed as study variables. Group comparisons used chi-square/Fisher's exact tests and the Mann-Whitney U test. Associations with clinician-suspected inflicted classification were examined using univariable logistic regression and a pre-specified exploratory multivariable Firth penalized logistic regression model. Fifty-eight children were included: 18/58 (31.0%) were classified as clinician-suspected inflicted drop/fall and 40/58 (69.0%) as accidental drop/fall. Clinician-suspected inflicted cases were older and more frequently had father reported as the caregiver. Bruising, displaced fractures, and multiple injuries/fractures were more frequent in clinician-suspected inflicted cases than in accidental cases. The combined pattern of bruising plus displaced fracture was observed in 12/18 (66.7%) clinician-suspected inflicted cases and 0/40 accidental cases in this sample, a zero-cell finding requiring cautious interpretation and external validation.In the pre-specified exploratory Firth penalized logistic regression model, father as the reported caregiver, bruising, and multiple injuries/fractures remained associated with clinician-suspected inflicted classification, rather than with independently confirmed abuse. In this single-center cohort, selected clinical and radiographic injury patterns were associated with clinician-suspected inflicted classification after caregiver-reported drop/fall from caregiver hold. Because abuse was not independently confirmed, these findings should be interpreted as risk indicators to support early safeguarding triage and careful documentation, not as stand-alone evidence of abuse or intent. Because clinician classification was not independent of routinely available clinical and radiographic findings, incorporation bias may have affected the observed associations. Bidirectional misclassification between accidental and clinician-suspected inflicted classifications may also have occurred. The absence of a full skeletal survey and uniformly documented complete examination may have led to missed occult injuries.
