Transphyseal Distal Humeral Fractures: A 13-Times-Greater Risk of Non-Accidental Trauma Compared with Supracondylar Humeral Fractures in Children Less Than 3 Years of Age

BACKGROUNDThe transphyseal distal humeral fracture has been well described as a concerning fracture pattern for non-accidental trauma (NAT) in young pediatric patients. Because of the infrequent presentation of this fracture, the association historically has been anecdotal. The purpose of this study was to determine and compare the incidence of NAT among displaced transphyseal distal humeral fractures and displaced supracondylar humeral fractures in children
