There are four types of shoulder replacement surgeries, including –
Hemiarthroplasty – Only the ball and stem are replaced in this procedure. The ball is attached to the stem, which articulates with your natural socket.
Resurfacing Hemiarthroplasty – In this procedure, the humeral head’s joint surface is replaced with a prosthesis that is cap-like and doesn’t have a stem.
Anatomic Total Shoulder Replacement – On the humeral side, a metal ball is affixed to a stem, and on the glenoid socket, a plastic cup is used, to replace the arthritic joint, in this procedure.
Stemless Total Shoulder Arthroplasty – This procedure is a variant of total shoulder arthroplasty, to preserve bone. In this method, the metallic ball is joined to the upper arm without a stem.
Reverse Total Shoulder Replacement – The joint is essentially reversed in this procedure, with a metal ball replacing the glenoid socket and a plastic cup linked to the stem and transferred to the humerus.
