1. A method of repairing a distal radioulnar joint formed by a radius and an ulna, the method comprising:

  • cutting through a shaft region of the ulna to form a proximal ulnar fragment and a distal ulnar fragment;

    pivoting the distal ulnar fragment away from the proximal ulnar fragment to a pivoted configuration;

    removing bone from a sigmoid fossa region of the radius, from a generally laterally facing region of the distal ulnar head, or from both, while the distal ulnar fragment is in the pivoted configuration;

    installing a radial prosthesis, an ulnar prosthesis, or both, in place of bone that has been removed, to replace at least one surface region of the distal radioulnar joint; and

    fixing the proximal and distal ulnar fragments relative to each other.
