Stemless prostheses now used in primary shoulder replacements

Learn more about the stemless prosthesis used to replace the socket part of the shoulder joint during a primary shoulder replacement. Total shoulder replacement or shoulder arthroplasty is the replacement of the ball of the upper arm and socket of the shoulder blade with specially designed prostheses made of metal or ceramic (for the humeral head) and polyethylene, a medical grade plastic, for the socket.

These have now become smaller and are called stemless prostheses as, thanks to modern technology, there is no need to put a stem down the humerus. You can read more about primary shoulder replacements and the prostheses used during this procedure here.
