A joint prosthesis comprises two relatively inextensible primary components that are spaced apart from one another. Disposed between and spaced from both of the components is a pivot member. The pivot member is resiliently secured to each of the primary components so as to permit relative rotation between the primary components and the pivot member. As a result, the two primary components of the prosthesis can rotate toward and away from each other about an axis that is disposed at least adjacent to and at least approximately parallel to a central longitudinal axis of the pivot member. The pivot member and the primary components of the prosthesis are preferably secured together by one or more bodies of elastomer. |
