Aequalis^® Reversed Shoulder

Since the early 1990’s, specific principals for Reversed Shoulder Arthroplasty have been used by European shoulder surgeons with unmatched clinical success. As a result, a growing number of surgeons in the United States have begun to utilize a unique prosthesis incorporating these specific principals and the associated surgical techniques that go with it.

The Aequalis Reversed Shoulder Prosthesis was designed based on two bio-mechanical principles envisioned by Paul Grammont, M.D.. First, a medialized center of rotation located inside the glenoid bone surface and second, a 155 degree angle of inclination. Combined, they increase the deltoid lever arm by distalizing the humerus and make the prosthesis inherently stable.

The ‘Reversed’ technology is the result of over twelve years of clinical trials and rigorously documented research indicating the benefits of this product and the associated surgical techniques. The Aequalis has been the subject of dozens of research papers and articles in Europe and the United States.
