Transphyseal Injury of Distal Humerus: A Commonly Missed Diagnosis in Neonates.

Distal humeral physeal injury is a rare entity in newborns. Lack of ossific nuclei of the distal humerus in neonates results in a diagnostic dilemma as the injury is radiologically not visible and is often mistaken as elbow dislocation. Ultrasonography and Magnetic resonance imaging help to clinch diagnosis in the early period where plain radiographs fail to detect this entity. This condition warrants high index of suspicion along with good clinical acumen for early diagnosis and immediate management with closed reduction and immobilization to avoid long term complications. We present a case of delayed diagnosis of distal humeral physeal separation in a neonate which was managed conservatively at our neonatal intensive care unit with a good outcome without functional deformity.
