Neonatal Separation of Distal Humeral Epiphysis during Caesarean Section: A Case Report

We report a rare injury of distal humeral epiphyseal separation in a newborn during a Caesarean section. The diagnosis was made using magnetic resonance imaging. Emergency Caesarean deliveries with considerable traction applied to extract the baby can be the risk factor of such an injury.

Fracture Separation of the Distal Humeral Epiphysis in Children Younger Than Three Years Old

This study evaluated the change of carrying angle and the causes of cubitus varus after the fracture separation of the distal humeral epiphysis in young children. Twelve cases of fracture separation of distal humeral epiphysis were treated from January 1995 to July 1997. The age of all patients was younger than 3 years old. A metaphyseal fragment was seen in all cases (Salter-Harris type II), but the size of the metaphyseal fragment was either a very small flake or a large Thurston-Holland fragment. Posteromedial displacement was seen in all cases. There were three treatment groups: closed reduction with percutaneous pinning, closed reduction with cast, and cast without reduction. Follow-up period averaged 23.5 months (range, 12-40). Cubitus varus deformity was seen in seven cases, and six of them had a partial defect of the medial condyle that was avascular necrosis. The methods of treatment, age of injury, and the type of epiphyseal injury had no influence on the development of cubitus varus, but avascular necrosis of the medial condyle was related to the cubitus varus deformity (p<0.05). The results of this study suggest that fracture separation of distal humeral epiphysis in young children is likely to produce cubitus varus deformity with the development of avascular necrosis of the medial humeral condyle.

Separation of the entire distal humeral epiphysis.

In order to prevent unnecessary manipulation or open reduction, separation of the entire distal humeral epiphysis must be differentiated from dislocation of the elbow and fracture of the lateral condyle of the humerus. The keys are the relationship between the radius and capitellum and the direction of displacement of the radius and ulna, The normal relationship is maintained and the radius and ulna are medially displaced in separation of the distal humeral epiphysis. This relationship is disturbed in two other injuries and the bones of the forearm are laterally displaced in dislocation. Five cases are presented.
