A shoulder hemiarthroplasty is a partial shoulder replacement, which is the surgical removal of the rounded top portion of the humerus (the upper arm bone) and replacement with a prosthesis. This is the “ball” of the shoulder’s ball-and-socket joint, and it can become severely damaged due to chronic disease or an acute injury. Restoring the shoulder joint’s integrity through shoulder hemiarthroplasty can alleviate pain and help improve mobility.
What Is Shoulder Hemiarthroplasty?
The metal prothesis that is used to replace the head of the humerus during a shoulder hemiarthroplasty is secured in place with a metal stem that is positioned inside the long hollow portion of this bone. Regional anesthesia, general anesthesia, or a combination of both is used during the procedure.
The rounded head of the humerus naturally fits into the glenoid fossa, the curved opening of the scapula bone (shoulder blade). Within this glenohumeral joint, the ends of the bones are protected by cartilage. Ligaments, tendons, and the rotator cuff muscles give the joint a substantial range of motion. A shoulder hemiarthroplasty surgery may involve repair of other structures in the glenohumeral joint, but only the humeral head is replaced.
Purpose of Shoulder Hemiarthroplasty
The goal of a partial shoulder replacement is to reduce pain and improve mobility. You might benefit from a shoulder hemiarthroplasty if the head of your humerus bone is badly degenerated, fractured, or otherwise damaged and your glenoid fossa is in reasonably good condition.
Sometimes the best option is to replace the bone, and this surgery allows for that.
Shoulder symptoms that may improve after a shoulder hemiarthroplasty include:
- Decreased range of motion
