The shoulder, which is a ball and socket joint, is made up of 2 bones. These are:
The ball of the humerus fits into the glenoid socket, and articular cartilage and synovial membrane protect the bones. Muscles and tendons hold the shoulder together and provide stability. All of these components work together to allow the shoulder a good range of motion. When any of these components are severely damaged, your orthopedic surgeon may recommend shoulder replacement surgery. In this case, damaged bone and cartilage are removed and replaced with prosthetic components.
The shoulder replacement procedure involves replacing damaged cartilage and bone with prosthetic components. Prosthetic components used in shoulder replacement are made from a range of materials including metal, ceramic, and plastic. New technological advances in surgery mean that the procedure has good long-term results.
In a total shoulder replacement, your orthopedic surgeon will replace damaged surfaces with a metal ball, which is attached to a stem and a plastic socket. These components may be attached with cement.
Before you decide to undergo shoulder replacement surgery, your orthopedic surgeon will conduct a thorough physical examination. He may choose to use x-ray and MRI scans to confirm his diagnoses.
If you suffer from one of the following shoulder injuries, you may need a total shoulder replacement:
Before considering shoulder replacement surgery, an evaluation by an orthopedic surgeon is required. The procedure typically takes a few hours, and post-operative rehabilitation is essential.
When considering shoulder replacement surgery, bear in mind the following:
