At the top of the shoulder there is a connecting joint between the outer end of the Collar Bone and the upper portion of the Shoulder Blade. This small joint is often injured in contact sports such as football or with a direct blow of any kind to this area. Injury may range from a sprain or bruise, to an actual separation of the Collar Bone from the Shoulder Blade.The majority of these injuries are treated without surgery. If the bones are severely separated,then surgical repair may be required to reposition the bones.
