An allograft salvage technique for failure of the Darrach procedure: a report of four cases.

We report on four patients with failed resections of the distal ulna causing instability and impingement, who were treated with a tendon allograft to stabilize and buffer the ulnar stump. In three of the four patients the outcome was excellent. We believe that this new technique holds promise as an alternative salvage procedure for the failed Darrach resection.
