[Ultrasonographic diagnosis of an epiphyseal detachment of the upper end of the humerus due to birth injury].

Injuries to the proximal humerus in infants are often missed or misinterpreted because of the non ossification of the epiphysis. Ultrasound allows direct visualisation of the proximal humeral epiphysis, metaphysis, joint space, and relationship with the glenoid cavity. Ultrasound diagnosis of other epiphyses birth trauma has been reported. Ultrasound should be considered as the first imaging modality if traumatic epiphyseal dislocation is suspected in a newborn.
