Abstract: A surgical instrument including at least one tibial phantom generally corresponding to at least certain features of the tibial implant. The tibial phantom includes a top surface adapted to move freely against the prepared bottom end of the tibia. At least one talus phantom generally corresponding to at least certain features of the talus implant is engaged with the prepared top surface of the talus. At least one phantom skid is located between the tibial phantom and the talus phantom. The phantom skid is engaged with the tibial phantom such that dynamic engagement between the phantom skid and the talus phantom through at least extension and flexion of the ankle joint positions the tibial phantom on the prepared bottom end of the tibia. The phantom skid can either be a part of the tibial phantom or a separate component.

Abstract: 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.

Abstract: The knee prosthesis with rotary plate comprises a metal base (2) and a tibia plate (3) which are equipped with guide means (22, 22?, 22?, 26, 29, 5, 6, 5?, 9, 50, 51, 52, 13, 15, 18; 34, 34?, 34?, 35, 37, 7, 8, 10, 12, 53, 54, 55, 10?, 17) defining a center of rotation (C,C?) which may be offset from that of the tibia bone axis (YY?), so as to allow the tibia plate (3) to slide in rotation over the said base, the said guide means being positioned a certain distance away from the center of rotation (C, C?).
