Your shoulders are the joints where your upper-arm bones (humerus), shoulder blades (scapula), and collarbone (clavicle) meet. The humerus fits into the rounded socket of the scapula on each side of your body. Each shoulder is held in place by a group of four muscles and tendons, called a rotator cuff, which covers and protects the humerus and lets you raise and move your arm.
Common shoulder injuries include:
- Dislocation
- Separation
- Fracture
- Cartilage tear
- Rotate cuff tear
- Frozen shoulder
- Impingement
- Bursitis
