Abstract: A talar implant, comprising: a superior surface, defined by an arc having at least one first radius; an inferior surface, defined by an arc having at least one second radius, a lateral side; a medial side; a posterior portion having a first width; and an anterior portion having a second width; wherein the implant is configured to restore a tibio-talar joint tension, wherein the superior surface is separated from the inferior surface by a thickness, wherein the at least one first radius is smaller than the at least one second radius, wherein the center of the arc having at least one first radius is offset from the center of the arc having at least one second radius in at least one plane of the talar implant, and wherein the anterior portion further comprises an extension configured to provide support.

Abstract: In one embodiment, the present invention provides a talar implant, comprising: a. a superior surface, defined by an arc having at least one first radius; b. an inferior surface, defined by an arc having at least one second radius, c. a lateral side; d. a medial side; e. a posterior portion having a first width; and f an anterior portion having a second width; wherein the implant is configured to restore a joint tension between a tibio-talar joint in a neutral position, wherein the superior surface is separated from the inferior surface by a thickness, defining a height of the medial and lateral sides, wherein the at least one first radius is smaller than the at least one second radius, wherein the center of the arc having at least one first radius is offset from the center of the arc having at least one second radius in at least one plane of the talar implant selected from the group consisting of: a superior/inferior plane, an anterior/posterior plane, and a medial/lateral plane, wherein the inferior surface is configured to attach to a superior surface of the talus,and wherein the anterior portion further comprises an extension configured to provide support.
