Overview
Your shoulder is a complex joint made up of three bones: the scapula (shoulder blade), humerus (upper arm bone) and clavicle (collarbone). Fractures, sprains and strains are the most common shoulder injuries. A broken bone, shoulder sprain or shoulder strain may have similar symptoms, but they are different injuries that require specific care.
A shoulder fracture occurs when there is a partial or total break in one or more of the shoulder bones. Fractures are usually caused by a direct blow to the shoulder.
Sprains and strains are similar, but they affect different parts of the shoulder. A sprain means you have a stretched or torn ligament (connective tissue that connects bone to bone). This is sometimes called shoulder separation. A strain is the stretching or tearing of a muscle or tendon in the shoulder.
