This surgery replaces the damaged or diseased head of the humerus (also called the ball) and cartilage from the shoulder joint with a metal and plastic joint.
Humerus Head Removed
First, the surgeon removes the head of the humerus bone.
The surgeon then smoothes and reshapes the shoulder socket (the glenoid).
Plastic Component Attached
The plastic glenoid component is pressed into place with bone cement.
Bone Hollowed Out
The surgeon hollows out the upper portion of the humerus to receive the implant.
Metal Stem Implanted
The metal stem is implanted in the humerus. It may be secured with bone cement.
Metal Head Attached
A metal ball is placed onto the stem.
End of Procedure
The surgeon joins the repaired humerus and glenoid components to form the new shoulder joint.
