However, posterior dislocations deserve more attention due to the far higher incidence of associated complications.1 Also, since the medial clavicular physis closes relatively late in life, what appears to be a posterior sternoclavicular dislocation in young patients may actually be a medial epiphyseal disruption with posterior displacement.4
