Claim Text:
1. A prosthetic ankle assembly comprising: an astragalar component comprising an upper articular surface that forms part of an ankle joint prosthesis and a lower surface comprising a shape adapted to engage an upper face of an astragalus; and an astragalocalcanean rod sized to be positioned in a bore extending completely through the astragalus and a calcaneus of an ankle, the astragalocalcanean rod comprising a first end, which is adapted to couple to the lower surface of the astragalar component, and a second end adapted to engage with a lower surface of the calcaneus, such that during implantation, the astragalocalcanean rod is configured to be inserted through a lower face of the calcaneus so that the first end of the astragalocalcanean rod is coupled to the lower surface of the astragalar component that is engaging the upper face of the astragalus, and wherein the second end of the astragalocalcanean rod both approximates and engages the lower face of the calcaneus so as to progressively compress the calcaneus against the astragalus as the rod advances into the calcaneus from its lower face, resulting in an arthrodesis between the calcaneus and the astragalus.
