Chondro-epiphyseal separation of the distal humerus in the newborn. A case report and review of the literature.
Chondro-epiphyseal separation of the distal humerus is a rare injury, and when it occurs in the newborn, it may be difficult to diagnose and is easily mistaken for a dislocation of the elbow. The unimpressive clinical appearance of such an injury of the elbow in an infant, as well as the absence of ossific nuclei of the distal humerus in the newborn, are responsible for the dilemma in making the diagnosis. Ultrasonography, a readily available, non-invasive technique, can be used to evaluate the non-ossified epiphysis about the elbow of infants to demonstrate dislocations, fractures, and physeal separations. Closed reduction with or without percutaneous Kirschner wire fixation is the treatment of choice for these injuries. In this article, we report on a case of complete epiphyseal separation in a neonate and discuss the problems arising in its diagnosis.
