Keller's arthroplasty: is distraction useful? A prospective trial.
There are many operations for hallux valgus and hallux rigidus, but Keller's operation remains one of the most popular, particularly for the older patient. A prospective trial was carried out to compare the results of Keller's operation modified by Kirschner-wire distraction with those of the standard operation. The results suggest that there is no advantage in using temporary Kirschner-wire distraction; indeed, degenerative changes in the interphalangeal joint and a subjectively worse result may result from its use.
