Shoulder replacements are usually performed to relieve pain. The most common type of shoulder replacement involves replacing the damaged bone and cartilage with a highly polished metal ball attached to a stem and a plastic socket.
Much like the hip joint, the shoulder is a ball-and-socket joint. The ball is the top of the humerus (arm bone) and the socket is within the scapula (shoulder blade). The design of this joint allows individuals a great range of motion at the shoulder.
Total Shoulder Replacement Procedure
- The ball is first removed from the top of the arm bone (humerus) and then replaced with the metal implant.
- This implant is shaped like a half-moon and is attached to a stem that is inserted down the center of the arm bone.
- The socket portion of the joint is then shaved clean and replaced with the plastic socket that is cemented into the shoulder blade.
Reverse Total Shoulder Replacement Procedure
- Socket and metal ball are opposite of a conventional total shoulder replacement.
- The metal ball is fixed to the glenoid while the plastic cup is fixed to the upper end of the humerus.
Post-Treatment
- Pain will most likely be felt which is a natural process of healing.
- Pain medication is often prescribed short term.
- Physical Therapy will be prescribed to help regain motion and strength.
Complications may arise which could include infection, excessive bleeding, blood clots, and damage to blood vessels or nerves.
