There are two ways to replace the shoulder joint: through conventional total arthroplasty or reverse total arthroplasty. Your surgeon will decide which technique is best for you depending on the nature of your injury. In conventional total athroplasty, the prostheses match the shoulder anatomy – the shoulder socket is replaced by a plastic cup, and the ball is replaced by metal prosthesis at the top of the humerus. During reverse shoulder arthropolasty, the positions of the prosetheses are switched – the metal ball is placed in the socket, the cup is placed at the top of the humerus. This technique is appropriate for patients with large rotator cuff tears.
Our team will complete a CT scan of the shoulder prior to surgery in order to discover the joint’s precise size and shape. We work with a bioengineering firm to create custom tools to use during computer-assisted surgery, where we position the prosthesis at the perfect depth, angle, and height for the patient.
