Abstract
Since 1989 scapholunate fusion has been performed on 13 patients with chronic scapholunate instability causing debilitating symptoms. These cases were reviewed at a mean 93 (range, 60–132) months after surgery. Establishing whether bony fusion had been achieved proved extremely difficult even after CT scanning, but fusion was unequivocally achieved in four cases. Ten patients were subjectively satisfied with their treatment. Two patients who had no symptomatic improvement subsequently underwent total wrist arthrodesis. A method of fusing the scaphoid and lunate is described, though we accept that a firm fibrous union may be all that is achieved in most patients. However, this appears sufficient to restore stability with a high patient satisfaction.
