Fracture-Separation of the Lower Humeral Epiphysis in Young Children

Abstract

Five fracture-separations of the lower humeral epiphysis, type II according to the Salter-Harris classification, are presented. The fracture line generally passes through the cartilaginous epiphysis, which does not show up in roentgenograms, and sometimes included a laterally based metaphyseal wedge. This injury is often misdiagnosed as it is mistaken for other injuries of the elbow, especially fracture of the lateral humeral condyle. The concomitant displacement of the radius and ulna in relations to the capitellar ossification center is the key to the diagnosis of fracture-separation of the lower humeral epiphysis. Good results are obtained with treatment by closed methods if this lesion is correctly diagnosed.

“…Many authors agreed on this point. 4,11,13,14,26,27 Therefore, anatomical reduction should always be achieved as from an anatomical point of view, when compared with supracondylar fractures, the area of fracture contact is greater, medial tilt is less important and rotation of the distal part of the humerus is less. 19…”
