Total / Partial Shoulder Replacement

 

The shoulder is a ball and socket joint. The round end of the arm bone fits into the opening at the end of the shoulder blade, called the socket. This type of joint allows you to move your arm in most directions.

 

For total shoulder replacement, the round end of your arm bone will be replaced with an artificial stem that has a rounded metal head. The socket part of your shoulder blade will be replaced with a smooth plastic shell (lining) that will be held in place with a special cement. If only 1 of these 2 bones needs to be replaced, the surgery is called a partial shoulder replacement, or a hemiarthroplasty.

 

Shoulder Resurfacing

 

In Shoulder Resurfacing, the surface of the bony end is made smooth and the diseased part is removed in the process. After this, a metal cap shaped to fit into the socket is fixed on the end of the bone.
