Shoulder Replacement Surgery

Shoulder surgery used to mean the end of an active lifestyle.  Not any longer.  

As you move your arm, the ball shaped end of the upper arm, the humerus, slides against the cuplike depression in the shoulder bone, the scapula.  As long as the upper arm can slide against the shoulder, you can move your arm comfortably.

Overtime, the should joint can wear down, particularly in patients with arthritis.  Cartilage, the protective tissue that cushions the bones and makes it possible for them to move smoothly against each other, wears away.  This causes the bones to run together, causing pain and restricting arm range of motion.

Shoulder replacement surgery involves removing the ball-shaped end of the humerus, and replacing it with a metal substitute.
