Ankle replacement system

An ankle replacement prosthesis that traverses a joint between a talus and a calcaneus comprising

• a generally convex artificial joint replacement;
• and
• a rigid prosthesis body including a superior portion sized and arranged to attach to a talus, an inferior portion sized and arranged to attach to a calcaneus, and a median portion sized and arranged to traverse the joint and prevent movement of the joint, the superior portion including a component sized and arranged to support the artificial joint replacement without extending into the tibia.

An ankle replacement prosthesis comprising

• a lower prosthesis body sized and arranged to attach to a calcaneus, the lower prosthesis body having an essentially straight medial border and curved lateral border which curves medially-from front to back of the body.

• the superior portion including an overhang portion which includes a region sized and arranged to attach to the calcaneus and/or talus.

An ankle replacement prosthesis comprising

• a lower prosthesis body, the lower prosthesis body being adapted to attach to both a talus and a calcaneus, wherein the lower prosthesis body fuses the talus to the calcaneus, the lower prosthesis body including a superior portion of the talus and a component sized and arranged to support a convex artificial joint replacement without extending into the tibia.
