Posterior fracture through the sternoclavicular physis associated with a clavicle fracture: a case report and literature review.

Three reported cases of fractures in teenagers of the medial clavicle associated with a posterior disruption at the sternoclavicular joint have similar findings. The medial fragment is rotated 90 degrees to the coronal plane. The medial fragment is usually stripped of its periosteum. Treatment requires open reduction and internal fixation of the clavicle fracture. We are reporting similar findings in a fourth case.
