Abstract
Background
Distal femoral metaphyseal fractures in children pose diagnostic challenges due to potential accidental and non-accidental aetiologies. This review aims to critically analyse the evidence on the association between distal femoral metaphyseal fractures and child abuse, as well as fracture patterns aiding in distinguishing inflicted injuries from accidental injuries.
Methods
A systematic review of studies involving children with distal femoral metaphyseal fractures was conducted, examining the reported associations with child abuse, fracture patterns and proposed mechanisms.
Results
The review revealed a significant association between distal femoral metaphyseal fractures and child abuse, particularly in non-ambulatory infants. However, some fractures may occur accidentally, often from short falls with direct impact on the knee. Certain fracture patterns, such as transverse or oblique configurations, suggest abuse, while spiral or buckle patterns are more likely accidental. Case series and retrospective studies reported varying findings, with some studies supporting a strong association with abuse and others highlighting the potential for accidental mechanisms.
Conclusions
A comprehensive evaluation, including history, physical examination, skeletal survey and multidisciplinary collaboration, is crucial for accurate diagnosis and management. Healthcare professionals should maintain a high index of suspicion for child abuse while recognising accidental mechanisms. Specific recommendations for healthcare professionals and future research directions are provided.
