Shoulder pain is an enormously common and there are many causes associated with the problem. Arthritis is one of the commonest causes in elderly people. It is a condition which affects cartilage of joints.

Shoulder arthritis causes cartilage of joint to wear out thin & expose the open bone as cartllageliining wear away the defensive lining between the bones will be lost & this is main cause of shoulder pain. Muscular shoulder arthritis is very painful & can result in the constraint of normal activities. The pain may be tolerated with use of some medication for some time, but there may come a time when surgery is required.

Shoulder is third common joint after knee shoulder which requires replacement for treating pain due to arthritis. Total or Partial shoulder Replacement with prosthetic joint reduces pain and restore independence. Surgeon installs artificial ball and joint into the shoulder. The ball is removed from the top of the humerus and replaced with a metal implant. The metal implant is shaped like a half moon & attached to a stem inserted down the center of the arm bone. The socket portion of the joint is replaced with a plastic socket, cemented into scapula.

People who experience pain in the shoulder with developed arthritis or structural injury of the shoulder are often accompanied by intense pain & inability to raise the arm above shoulder level, soft tissue damage to the rotator cuff. (Group of muscles stabilizing the shoulder) can render a person unable to perform daily activities like bathing or dressing.

When damage to Rotator cuff is severe, then Surgeon may advise REVERSE TOTAL SHOULDER REPLACEMENT SURGERY (RTSA). In RTSA, socket prosthesis replaces the rounded end of humerus and metal ball is installed into gleroidfussa (shoulder socket). This allows delloid muscle to become elevator in the shoulder instead damaged and torn rotator cuff muscle.
