Shoulder Replacement Surgery

The shoulder joint consists of a shoulder blade (scapula) and an arm bone (humerus).

This joint is what is known as a ball (head of the humerus) and socket (glenoid fossa of the scapula) joint. In a healthy shoulder, the surfaces of the ball and socket are covered in cartilage. The cartilage acts as a protective barrier to the bones that touch each other allowing for smooth, pain-free motion.

Due to arthritis or injury, this cartilage sometimes becomes worn and no longer provides the protection needed to pad the joint. This results in painful movement and decreased functional use of the arm. In some cases, conservative treatments, such as medications and modifications of daily activities, no longer provide adequate pain relief. Then, a total shoulder replacement may become the best form of treatment to regain pain-free motion and functional use of the arm.

In shoulder replacement surgery, the damaged parts of the shoulder are removed and replaced with artificial components. There are several shoulder replacement options, which include the following:<
