Allograft tendon interposition and brachioradialis tendon stability augmentation in revision surgery for failed...

Achilles allograft interposition is one treatment alternative for failed Darrach distal ulna resections, good results have been reported with its use but concern remains with the stability of the distal ulnar stump. The use of brachioradialis tendon passed through the radius and then divided in to 2 branches to pass over the volar and dorsal aspect of the ulnar stump with the Achilles tendon interposition, seems to represent a more reliable, secure, and biological way of restoring palmar and dorsal stability to the distal ulnar stump; while it allows a better control of the tension given to the Achilles allograft interposed than that achieved when using only suture anchors as described in the original technique.
