Hemi, Total, Reverse. There are three basic types of options for shoulder arthritis. The first is the hemiarthroplasty, where you just replace the ball of the shoulder. The second is the total shoulder arthroplasty, where you replace the ball and the socket. The third is the reverse shoulder arthroplasty and is used in certain situations of arthritis but without a working rotator cuff.
