Shoulder Arthritis TreatmentsThere are much more simple treatments for shoulder arthritis that should be tried before considering shoulder replacement surgery. Because the shoulder is not a weight-bearing joint (like the knees and hips), many patients can tolerate shoulder arthritis with some simple treatments and modifications of their activities.
Shoulder Replacement SurgeryTotal shoulder replacement surgery alleviates pain by replacing the damaged bone and cartilage with a metal and plastic implant. The shoulder joint is a ball-and-socket joint, much like the hip joint. The ball is the top of the arm bone (the humerus), and the socket is within the shoulder blade (scapula). This joint allows people an enormous range of motion at the shoulder.
When shoulder replacement surgery is performed, the ball is removed from the top of the humerus and replaced with a metal implant. This is shaped like a half-moon and attached to a stem inserted down the center of the arm bone. The socket portion of the joint is shaved clean and replaced with a plastic socket that is cemented into the shoulder blade.
