Abstract

A prosthesis for reconstruction of a distal radioulnar joint, after resection of a part of the ulna, includes a first prosthesis member, fixation members and a second prosthesis member. The first prosthesis member is configured for fixation to the distal end portion of the ulna. The fixation members are configured to extend into the radius via said distal end portion of the ulna for locking said distal end portion of the ulna to the radius. The second prosthesis member is configured for fixation to the ulna close to said distal end portion of the ulna. The second prosthesis member is also configured to extend into said space for being joined with the first prosthesis member in a manner which allows said first and second prosthesis members to at least pivot and rotate relative to each other.
