Abstract
A method for restoration of stability and painfree rotation of the distal radio-ulna joint is based on raising the capsulo-retinacular flap by dissection off the dorsal part of the triangular fibro-cartilage complex distally and off the neck of the ulna proximally. After resection of the ulna head and reaming the distal end of the ulna to an appropriate depth and inserting the prosthesis into a suitable position the dorsal aspect of the triangular fibro-cartilage complex is reattached to the underside of the flap. Finally, the flap is reattached to the sigmoid notch of the radius and the wound is closed. By this way, painfree forearm rotation is restored and at the same time any length discrepancy is corrected.

A surgical procedure for restoration of stability and painfree rotation of the distal radio-ulnar joint comprising the steps of:
- dorsal incision centered over the distal radio-ulnar joint;
- raising the capsulo-retinacular flap by incising through the capsule and dissection off the dorsal part of the triangular fibro-cartilage complex distally and off the neck of the ulna proximally;
- resection of the ulna head;
- reaming the distal end of the ulna to an appropriate depth and inserting the prosthesis into a suitable position;
- reattachment of the dorsal aspect of the triangular fibro-cartilage complex to the underside of the flap and reattachment of the flap to the sigmoid notch of the radius and closing the wound.
