Fusion of the metarcarpophalangeal joint of the thumb is an accepted treatment in the management of instability or osteoarthritis following trauma to this joint. A review was made of the literature and 30 of the senior author's (RH) patients who had had this operation, in order to determine what effect the operation had on the pain in their thumb, any symptoms of instability, interference with work and daily activities, and strength in the hand. All of the patients achieved bony union and the average angle of fusion was 7.6 degrees of flexion. All of the patients were either satisfied or very satisfied with the results of the operation, and had an average increase of 6.3 points on a 12 point rating scale. However, 48% of patients had some mild intermittent pain and 43% complained of some difficulty with fine motor tasks. Twelve patients were able to attend for formal evaluation including the Jebson and Crawford Hand Function Tests which revealed some decrease in hand function in all of those tested. It was concluded that this method of arthrodesis of the metacarpophalangeal joint of the thumb gives reliable results, with high patient acceptance, but does not result in an entirely normal thumb or hand function.
