PROSTHESIS FOR RECONSTRUCTION OF DISTAL AND PROXIMAL RADIOULNAR JOINTS

摘要

A prosthesis (1) for reconstruction of a distal radioulnar joint after resection of a part of the ulna close to a distal end portion (U1) thereof, comprises a first prosthesis member (2), fixation means (3) and a second prosthesis member (4). The first prosthesis member (2) is configured for fixation to the distal end portion (U1) of the ulna. The fixation means (3) 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 (4) is configured for fixation to the ulna (U2) proximally of a space (US) which is defined between the distal end portion (U1) of the ulna and the ulna proximally of said space by the resection of said part of the ulna close to said distal end portion of the ulna. The second prosthesis member (4) is also configured to extend into said space (US) for being joined with the first prosthesis member (2) in a manner which allows said first and second prosthesis members to at least pivot and rotate relative to each other. Said prosthesis may be used also for reconstruction of a proximal radioulnar joint.
