Patent number: 7993346Abstract: A method for implanting a malleolar implant in an ankle joint. A spacer block is positioned between a lower portion of a tibia and an upper portion of an astragalus in the ankle joint. A guide attached to the spacer block is positioned opposite an outer surface of a fibular malleolus. A bore aligned with the guide is formed through the fibular malleolus. The spacer block is removed from between the tibia and the astragalus. A shank of the malleolar implant is engaged with the bore from an inner surface of the fibular malleolus. The shank is advanced into the bore so an inner surface of a head of the malleolar implant engages the inner surface of the fibular malleolus.Type: GrantFiled: October 27, 2008Date of Patent: August 9, 2011Assignee: Tornier SASInventors: Alain Tornier, Michel Bonnin, Jean-Alain Colombier, Thierry Judet
