Abstract
A talar dome is provided as an element of a total ankle arthroplasty, to fit over a resected talus bone. The talar dome has an integral dome body with a smooth and rounded superior articulating side facing the tibia, and an inferior mounting side with mutually inclined flat faces that complement the flat surfaces of the resected talus. On the inferior or mounting side, the talar dome has at least two pegs integral with and rigidly protruding from the dome body. The pegs each taper along flat faces to a point that is embedded in the talus bone for operatively attaching the talar dome to the talus bone. At least one flat face is of each peg is perpendicular to the sagittal plane and resists anterior/posterior displacement of the talar dome until healed.
