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 orthopaedic 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 successful long-term results. In a total shoulder replacement, your orthopaedic 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.
The reverse shoulder replacement procedure on the other hand, is done for a small amount of people who lose function due to a massive rupture of the rotary cuff. In these cases, the muscles which are involved in shoulder movement are significantly disabled and thus the shoulder is thus not functional. This surgery then involves the inverse of the traditional shoulder replacement surgery.
Your orthopaedic surgeon will know which of the two surgeries you will need to regain functioning of the shoulder.
Before you decide to undergo shoulder replacement surgery, your orthopaedic surgeon will conduct a thorough physical examination in which 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:
Recovery will depend on the severity of your injury, as well as your personal condition. Speak to your orthopaedic surgeon about rehabilitation, physical therapy, and any lifestyle changes that might be required.
Before considering shoulder replacement surgery, an evaluation by an orthopaedic 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:
