Do you have shoulder pain that keeps you up at night? Has it gotten difficult to comb your hair or reach up to the top shelf?\nRotator cuff injuries are a common cause of shoulder pain, and new surgical options give you choices for treating even severe injuries. Depending upon your doctor\u2019s recommendations, you may opt for traditional shoulder replacement or a newer procedure known as a reverse shoulder replacement.\nHow the Shoulder Works\nYour shoulder joint is made up of three bones:\n\nThe collarbone\nThe shoulder bone\nThe bone of your upper arm\n\nThe head of your upper arm bone fits into a hollow in the shoulder bone \u2014 that forms the ball and socket you\u2019ve probably heard of before. A group of four muscles, along with tendons, surround the joint and keep your arm steady. These muscles are your rotator cuff.\nRotator cuff injury causes\nRepetitive arm motion, arthritis, and certain sports can lead to rotator cuff injuries. Arthritis compounds the pain and difficulty of a rotator cuff injury.\nWhat Is Shoulder Surgery?\nWhen the pain becomes severe or you lose most of your mobility in your shoulder, your doctor may recommend shoulder replacement surgery.\nYou have two shoulder surgery options:\n\nTraditional total shoulder replacement, which replaces the arm bone and the shoulder socket\nNewer reverse shoulder replacement\n\nWhat Is a Reverse Shoulder Replacement?\nIn reverse shoulder replacement surgery, the ball is replaced with a socket, and the socket is replaced with a ball. A rounded joint piece, the ball, is attached to the shoulder bone, and a cup-shaped piece, the socket, replaces the top of the arm bone.\nWho is a candidate for reverse shoulder replacement surgery?\nYour doctor may recommend this surgery if you have severe damage to your rotator cuff or the muscles don\u2019t work properly, as with cases of rheumatoid arthritis. In a traditional shoulder replacement, the limited range of your rotator cuff would also affect the movement you can regain after surgery.\nWith the reverse shoulder replacement, your deltoid muscle, the large muscle group that forms the contour of your shoulder, is used to move your arm. You may be able to regain more overhead reach with this surgery than the traditional.\nReverse shoulder replacements now make up about half of all shoulder replacement surgeries.\nAs with any major surgery, it will take months to recover along with a rigorous rehabilitation program. Physical therapy after surgery will help you lift your arm and regain as much ability to reach overhead as possible.\nDo you have a shoulder injury that is causing you chronic pain?
