ABSTRACT:
A distal component for a wrist prosthesis that utilizes fixation within the carpus complex, incorporates features that improve the probability of intercarpal fusion and allows modularity of articulating components. In one form, the subject invention includes an ovoid fixation plate having three holes and a boss. The three holes allow attachment of stems and/or screws distally for fixation in the carpus. The boss projects proximally from the plate, and serves as an attachment point for the articulating head. Modularity of the fixation and articulating components allow a surgeon many options for optimizing fixation distally, and articulation proximally. The proximal head of the distal component is designed to articulate with existing radial components. Since the proximal head of the distal component is modular, however, the head can be redesigned to accommodate later design changes in proximal components.
