Abstract

See full text

A joint prosthesis for interconnecting the ends of adjoining bones includes a cushion of expanded PTFE having at least two facets for attachment to the bones. The cushion may or may not include stems for insertion into the bones. An optional sheath surrounds the non-facet surfaces of the cushion for preventing adherence of tissue. The motion of the prosthesis is defined or limited by the orientation of the facets and/or by the porosity of the cushion and/or by an insert within the cushion.
