In briefThe sternoclavicular (SC) joint can incur significant injuries. These injuries are often subtle, and, without a high index of suspicion, hard to diagnose. However, specific diagnostic methods can help clarify the extent of injury, and relatively straightforward treatment protocols can help resolve all but the most severe injuries. Two areas of concern are physeal injuries and posterior dislocations. In children and young adults, injuries of the SC joint must be considered physeal fractures until proven otherwise. Disastrous complications of posterior SC dislocations have been reported, but detecting vascular compromise or other serious sequelae will help minimize their occurrence.
