Talar implant system and method

A method of implanting a permanent talar implant assembly including an articulation component, a base member with a cylindrical bore, and a distal portion with a solid spherical head, the method comprising:

• providing the articulation component;
• providing the base member;
• providing the distal portion;
• coupling the provided articulation component having an articulating surface extending upwardly from a first plane to an apex and then downwardly toward the first plane, and configured to articulate with a tibial prosthetic device, with the provided base member, at least one of the provided articulation component and the provided base member having a planar portion defining the first plane;
• selecting an angular position for a longitudinal axis of the provided distal portion with respect to the first plane from a range of angular positions within a second plane perpendicular to the first plane, wherein the solid spherical head and the cylindrical bore are configured to allow the solid spherical head to be positioned in the cylindrical bore at any of a plurality of relative orientations, of the solid spherical head and the cylindrical bore, which define the range of angular positions and the provided distal portion and the provided base member are couplable at each of a plurality of angular positions within the range of angular positions;
• orienting the provided distal portion with the provided base member at the selected angular position with the solid spherical head at least partially within the cylindrical bore;
• rigidly frictionally coupling the oriented provided distal portion with the provided base member at the selected angular position with a rigid friction coupling sufficient for permanent implantation of the permanent talar implant assembly;
• and
• implanting the provided distal portion in at least one bone of a foot.
