[Traumatic distal humerus epiphysiolysis in a newborn child].

Traumatic distal humerus epiphysiolysis (TDHE) is a rare injury in infants with an incidence of about 1:35,000 births. It is primarily a birth injury, but it is also seen in cases of battered child syndrome. Because of its rare occurrence and the diagnostic difficulties, the lesion may be overlooked or misdiagnosed on initial presentation. The diagnosis is made on the basis of a high index of suspicion, clinical signs and symptoms and awareness of radiological changes. Traumatic humeral dislocation will produce the same radiological picture as TDHE and is consequently a common, incorrect initial diagnosis. We present a case of TDHE as a birth injury.
