When shoulder replacement may be right for you
Shoulder replacement surgery is usually considered when severe pain, stiffness, weakness, or arthritis keeps you from doing daily tasks. It may be an option when treatments like medication, injections, or physical therapy no longer provide relief.
There are different types of shoulder replacements. Your surgeon will talk with you about which option best fits your shoulder condition, goals, and lifestyle.
Total shoulder replacement removes the damaged joint surfaces and replaces them with a smooth metal ball and a plastic socket. These parts come in different sizes and may be placed with or without cement, depending on your bone quality. This surgery works well for people with bone-on-bone osteoarthritis and an intact rotator cuff.
A hemiarthroplasty replaces only the ball portion of the shoulder joint with a metal ball and stem. It may be recommended for severe shoulder fractures or certain types of arthritis when the socket is still in good condition.
In a reverse total shoulder replacement, the positions of the ball and socket are switched. The metal ball is placed on the shoulder blade side, and a plastic socket is placed on the upper arm bone. This design allows the deltoid muscle to lift the arm when the rotator cuff is completely torn or too damaged to repair.
