In an acromioclavicular injury, the ligaments that bind the clavicle and a part of the shoulder blade called the acromion are torn, says the American Academy of Orthopaedic Surgeons. This leads to immediate pain and swelling. Sometimes, the area is too painful to move, and the patient's arm may need to be in a sling for a period of time. The area may remain deformed even after healing, but the patient still has a good range of motion.

The sternoclavicular injury happens when the ligament that binds the sternum and the clavicle together is torn, according to About.com. This is an uncommon injury, but can be serious because the area contains such important structures as major blood vessels and the windpipe.
