Shoulder Hemiarthroplasty Everything You Need To Know

A shoulder hemiarthroplasty, or partial shoulder replacement, is surgery to remove the rounded top portion of the humerus (the upper arm bone) and replace it with a prosthesis. This is the "ball" of the shoulder's ball-and-socket joint, and it can become severely damaged due to chronic disease or an acute injury. Restoring the shoulder joint's integrity through shoulder hemiarthroplasty can alleviate pain and help improve mobility.
