Sternoclavicular epiphyseal separation with adjacent clavicular fracture

An unusual case of a double fracture of the medial left clavicle in a 15-year-old male hockey player is presented. One fracture was an epiphyseal separation through the medial growth plate and the second a transverse fracture of the medial one-third of the same clavicle with displacement of the fragment into the chest. Radiographic and computed tomographic descriptions are presented. The injury was managed with open reduction and fixation. A discussion of sternoclavicular epiphyseal separations and intrathoracic displacement is given, with a review of the literature.
