Hemiarthroplasty is a surgical procedure that replaces one half of the shoulder joint.
The humeral head is replaced with a prosthesis and glenoid is left as such. It is performed in the case of severe fractures of the humeral head, and avascular necrosis in which the humeral head bone is compromised with poor blood flow.
It is considered when injections and physiotherapy fail to correct shoulder injures.
When Do You Require Shoulder Hemiarthroplasty?
- Pain from glenohumeral osteoarthritis
- Those at risk for loosening of glenoid components, such as those who require heavy usage of the shoulder
- Glenohumeral arthritis in which there is inadequate glenoid bone
- Fractures associated with poor bone quality and dislocation of the head of the humerus
- Rheumatoid arthritis
- Osteoarthritis of glenohumeral joint
- Avascular necrosis
- Glenohumeral chondrolysis
- Rotator cuff tear arthropathy
- Arthritis and tumors
