What is Shoulder Instability?
The humerus (arm bone), the glenoid cavity of the scapula (shoulder blade), and clavicle (collarbone) are the bones that make up the shoulder joint. Important structures that stabilize the joint are:
- Ligaments connect bones to bones.
- Tendons connect muscles to bones.
- The glenoid labrum helps the humerus fit perfectly in the glenoid cavity.
An injury to any of these important structures can cause shoulder instability. Common injuries are rotator cuff, glenoid labrum partial and complete tears.
