Abstract
Provided is a total talar replacement prosthesis that has a metallic body shell and a metallic or biologic core, where the metallic body shell includes one or both of a removable calcaneus attachment and a removable navicular attachment. The attachments, when removed, exposes a respective calcaneus-facing surface or a navicular-facing surface that can enhance fusion to the respective bones, calcaneus and/or navicular.
Claims20
A total talar replacement prosthesis comprising:
- a metallic body shell that partially encloses a core wherein the metallic body shell includes a calcaneus-facing surface a portion of which defines a discontinuity that exposes the core;
- and
- a calcaneus attachment configured to:
- (i) be removably attached to the calcaneus-facing surface;
- and
- (ii) removably cover at least a portion of the exposed core by at least partially filling the discontinuity of the metallic body shell, wherein the core is a metallic or biologic cancellous matrix core.
