It is still controversial whether stimulation by electromagnetic fields is effective in the treatment of bony nonunion. We conducted experiments to study the optimal stimulation of electromagnetic fields for nonunion and used an electromagnetic fields pulse generator manufactured by the Institute of Physical and Chemical Reserch. Ten patients with nonunion (9 traumatic nonunion, one congenital pseudoarthrosis) were entered in the study. The site of nonunion was the femur in 4 patients, tibia in 3, humerus in 2, and radius in one. Results were as follows: The rate of bone union was 80%. For traumatic nonunion cases the period to union ranged from 3 to 5 months. However, it took 8 months to obtain bone union in the case of congenital pseudoarthrosis. Stimulation by electromagnetic fields is an effective method of treatment for nonunion.
