This device exemplifies the next generation in disc replacement and offers mobility equal to the body’s natural components. When bonded to the metal, the polymer core mimics a natural disc, absorbing impact and shock while bearing mechanical stresses from the vertebrae. The R&D, brainstorming and solutions provided by the group are outstanding.
