Stabilisation of distal ulna after excessive Darrach's procedure

A patient is presented in whom painful instability persisted more than a year after the resection of 1 1/2 inches of the distal ulna, for a painfully subluxed distal radio-ulnar joint. The palmaris longus tendon was detached distally, passed through a drill hole in the distal radius and then wrapped and stitched, as a sling, around the distal ulna stump. Two years later the patient's symptoms were relieved.
