Shoulder Replacement for Fracture
Hemiarthroplasty is a shoulder replacement where the broken humeral head is replaced with an artificial joint and the fractured bone reconstructed around the artificial joint.
This is performed when the fracture is severely displaced. The blood supply to the humeral head is damaged and it is at risk of eroding if repaired. The head is therefore replaced, rather than repaired. This is more commonly performed in elderly people.
Below is a pictorial case report.
