A prosthetic ankle assembly including an astragalar component with an
upper articular surface that forms part of an ankle joint prosthesis and
a lower surface with a shape adapted to engage an upper face of an
astragalus. An astragalocalcanean rod is positioned in an
astragalocalcanean channel extending from the lower face of the calcaneus
to the upper surface of the astragalus. A first end of the
astragalocalcanean rod is engage with the lower surface of the astragalar
component and a second end of the astragalocalcanean rod is engaged with
a lower region of the calcaneus. A distance between the second end of the
astragalocalcanean rod is adjustable relative to the lower surface of the
astragalar component to adjustably compress the calcaneus against the
astragalus.
