Transphyseal fractures of the distal humerus often occur in children younger than 4 years as a result of birth trauma, nonaccidental trauma, or falls from a low height. It is important to identify and treat these injuries in a timely manner to ensure successful management. Most transphyseal fractures of the distal humerus are treated with closed reduction and percutaneous pinning with the aid of an elbow arthrogram. The most common complication following a fracture is cubitus varus caused by growth arrest, malunion, or osteonecrosis of the medial condyle. Normal carrying angles may be restored through corrective lateral closing wedge osteotomy.
