The SC joint forms the connection between the collarbone and the sternum. A meniscus is also interposed in this joint.
Fortunately, injuries to this joint are rare. They usually result from trauma-related subluxation, i.e. incomplete dislocation with loosening of the ligaments.
These injuries can take a long time to heal and in some cases can remain painful for a long time.
However, surgical reconstruction is rarely necessary. An operation is absolutely essential if the SC joint has dislocated backwards, i.e. inwards, as this injury can lead to serious problems in the neck organs.
Since this type of dislocation also tends to result in damage to the joint meniscus, it usually ends in subsequent SC arthrosis, with swelling and protrusion of the joint.
