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.
