DJO Discovery® Elbow System
The DJO Discovery® Elbow System is unique in that the components of the prosthesis have spherical condyles on the hinge portion. This allows for a more uniform distribution of stress across the artificial elbow, which theoretically prolongs the longevity of the prosthesis. Furthermore, the plastic liner that is inserted between the two metal components is infused with Vitamin E, which has been shown to minimize oxidation and overall reduce the wear of the prosthetic.
