Eight patients who had a recurrent pseudarthrosis of the carpal scaphoid
were treated by a bone graft from the ulna, vascularized by an ulnar-artery
pedicle. The graft was taken from the medial aspect of the distal third of
the ulna and inserted into the prepared scaphoid. This technique is
advocated only for complex recalcitrant non-union. All of our patients had
previously had at least two operations, one of which was conventional
non-vascularized bone-grafting. In all eight patients, primary osseous
union occurred in an average of 4.6 months; all were able to resume their
previous occupational or athletic activities.
