If you’re experiencing severe shoulder pain and loss of motion or weakness in your shoulder, total shoulder replacement surgery may be recommended. During a total shoulder replacement surgery, your shoulder doctor will replace the damaged bone and cartilage from your shoulder with a new ball-and-socket joint made of metal and plastic.
The new, artificial components fit into the top of your arm bone and your shoulder blade, restoring full function of your shoulder joint. During a total shoulder replacement surgery, your shoulder doctor will first remove the ball from the top of your arm bone, replacing it with a metal implant. Then, your doctor will clean the socket of your joint, removing the damaged portions and replacing your socket with a plastic component.
