This prosthesis is appropriately named as it makes a socket out of the patient's ball, and a ball out of the patient's socket, as shown in the picture above. Newer "reverse shoulder" prostheses make shoulder arthroplasty a reality for many patients with rotator cuff tears by reversing the positions of the components. The ball of the joint is placed in the glenoid, while the socket is positioned on the humerus. The U.S. Food and Drug Administration began approving reverse shoulder implants in the last decade.
In patients with a traditional shoulder replacement, the rotator cuff is essential for normal motion. When a patient has a rotator cuff tear AND arthritis, sometimes a reverse shoulder replacement is the only option. This unique procedure has helped decrease pain and restore function for patients with this combination of difficult problems.
Reverse shoulder replacement is not for everybody, and your surgeon must be highly trained and proficient in this technique. Dr. Bahu is specially trained in the treatment of shoulder arthritis and the use of reverse shoulder replacement. Dr. Bahu did a one year fellowship at Columbia University with one of the designers of the modern reverse shoulder replacement. To learn more visit our patient education page about shoulder arthritis

The health and strength of our bones rely on a balanced diet and a steady stream of nutrients, most importantly, calcium and Vitamin D.
Calcium is a mineral that people need to build and maintain strong bones and teeth. It is also very important for other physical functions, such as muscle control and blood circulation.
Calcium is not made in the body — it must be absorbed from the foods we eat. To effectively absorb calcium from food, our bodies need Vitamin D.
If we do not have enough calcium in our diets to keep our bodies functioning, calcium is removed from where it is stored in our bones. Over time, this causes our bones to grow weaker and may lead to osteoporosis — a disorder in which bones become very fragile.
Postmenopausal women are most vulnerable to osteoporosis. Although loss of estrogen is the primary reason for this, poor lifelong calcium and Vitamin D intake, as well as lack of exercise, play a role in the development of osteoporosis.
Note that men also are at risk for osteoporosis — typically later in life than women — and it is important for them to keep track of calcium intakes, as well.
Ever wonder how many joint replacement procedures are performed each year, if replacement surgery is permanent or how many men and women suffer from arthritis? Here are some answers to questions about hip and knee replacement surgery.
