Shoulder replacement surgery replaces the damaged bone and cartilage of the joint with polyethylene (a plastic material) and metallic components.
There are two types of total shoulder prosthesis:

Anatomic Shoulder Arthroplasty 
The humeral head is replaced with a metallic head assembled on a metallic stem. The glenoid is replaced with a plastic component.
The anatomic solution is usually recommended for patients with good rotator cuff.

Reverse Shoulder Arthroplasty 
The “normal” structure of the joint is reversed. The metallic ball is attached to the glenoid while the socket is on the humeral side.
The reverse solution is usually recommended in case of cuff tear arthropathy.


With almost 40 years of history, shoulder replacement surgery is a common and safe procedure for the treatment of severe arthritis and rotator cuff’s deficit.
The main benefits of a successful shoulder replacement are: 


Reduction in shoulder pain

Your pain should be dramatically reduced and usually eliminated.

Recovery of mobility

You should also regain close to the original mobility of your shoulder.

Improvement in quality of life

Your everyday activities and your social life should no longer be limited by pain and reduced mobility.
