Abstract

An ankle arthrodesis implant can include an elongate shaft sized and shaped to be implanted in an intramedullary canal of a tibia of a patient; a first angled opening through the shaft, the first angled opening defining a first axis that extends through the tibia and into a talus bone of the patient across a tibio-talar joint when the elongate shaft is implanted; a first elongate slot through the shaft, the first elongate slot defining a second axis that extends into the patient's talus when the elongate shaft is implanted, the first elongate slot being configured to allow a first fixation member to translate axially relative to the shaft within the first slot from a first position to a second different position to compress a tibio-talar joint, wherein the second axis is perpendicular to a sagittal plane of the ankle; a second elongate slot through the shaft, the second elongate slot defining a third axis that extends into a patient's calcaneus when the elongate shaft is implanted, the second elongate slot being configured to allow a second fixation member to translate axially relative to the shaft within the second slot from a first position to a second different position to compress a subtalar joint; a second angled opening through the shaft, the second angled opening defining a fourth axis that extends through the calcaneus and into a talus bone of the patient across the subtalar joint when the elongate shaft is implanted; and a third angled opening through the shaft, the third angled opening defining a fifth axis that extends into a calcaneus bone of the patient when the elongate shaft is implanted.
