A total shoulder replacement can restore the shoulder joint's smooth surface when it becomes rough and painful. This can provide much-needed pain relief and allows the soft tissues surrounding the shoulders to provide an improved range of motion. Total shoulder replacement, or shoulder arthroplasty, involves replacing the ball of the upper arm and socket of the shoulder blade with artificial implants made of metal and polyethylene. The upper arm socket component consists of a metal ball that replaces the humerus's head and a stem secured into the upper arm bone. The prosthesis is the shoulder blade socket is made of polyethylene and is used to replace the joint's socket. Our very own Dr. Dines is an inventor of one of the most popular shoulder replacement systems used worldwide, and our practice performs more than 300 shoulder replacements a year.
