Damage to your shoulder is painful and limiting. If a shoulder injury or condition is serious enough, a shoulder replacement may be the best option for regaining your mobility and independence. Some common reasons why you’d need a shoulder replacement include:
This is the most common form of shoulder replacement and involves attaching a plastic lining to the socket to allow smooth movement. The surgeon removes the top of the arm bone and inserts a metal stem with a ball on the end.
Anatomical total shoulder replacements are often conducted when a patient suffers from osteoarthritis or rheumatoid arthritis in the shoulder.
The rotator cuff is a group of muscles and tendons that hold the shoulder joint in place and allow you to move your arm and shoulder. Problems with the rotator cuff may cause weakness or pain and restrict movement. It may also cause damage to the shoulder joint.
Often, tendons can be repaired. However, if the tendons are severely damaged, an operation called reverse shoulder replacement may be a better way to improve the joint's function and reduce pain, especially if the joint is affected by arthritis.
This operation is also called reverse arthroplasty. "Arthro" means joint; "plasty" means to mold surgically.
In a reverse shoulder replacement, the normal ball-and-socket structure is reversed. An artificial ball is attached to the shoulder blade. An artificial socket is attached to the top of the arm bone. The large deltoid muscle that covers the shoulder is typically able to move the arm.
