Conditions

The shoulder is the most mobile joint in the human body. Because it is so flexible, the shoulder is highly susceptible to instability and injury.

If pain occurs when the humerus is rotated inwards, it is known as shoulder impingement syndrome. This can progress to a full tear of the rotator cuff.

Anyone is at risk of developing shoulder subluxation and/or dislocation; however, the risk for developing this condition is greater in people who excessively use this joint, including:

Adhesive capsulitis, more commonly referred to as frozen shoulder, is a condition that causes pain and stiffness in the shoulder.

The shoulder joint makes it possible to reach, lift, and grasp; however, this flexibility makes the shoulder more prone to injuries, including fractures.
