Generally, there are different kinds of diseases that could affect the shoulder joint:

degenerative - age related
traumatic - fracture or muscles/ligaments damage
post-traumatic - avascular necrosis as a result of trauma

Shoulder pain limits your daily activities, affects your mood, your health, and your general well-being.

The main causes of shoulder joint disease are the wear of the articular cartilage, called osteoarthritis, and the loosening of rotator cuff’s strength.
