Delta® shoulder prosthesis

The concept is, however, very much in its infancy and its place in the future of shoulder repair has yet to be determined. Encore Medical Corp. (Austin, TX) is currently conducting an investigational device exemption (IDE) study of its new Reverse Shoulder Prosthesis system (Figure 9.12). The first implantation in North America of another reverse prosthesis design (the Delta prosthesis [DePuy, Warsaw, IN]) was reported to have been conducted on February 27, 2003, hy Dr. Anthony Miniaci in Toronto, Canada (Canada Newswire 2003). The potential benefits of the concept are that it can allow better function than standard prostheses without relying on rotator cuff function and that it can decrease bending moment forces at the prosthesis-glenoid interface. If these benefits are clinically realized, then it could become an important addition to standard prostheses, especially in difficult arthroplasty cases.
