Experimental model of electric stimulation of pseudarthrosis healing.
The effect of electric stimulation with direct constant current in induced pseudarthrosis was investigated in the radius of adult dogs. Two surgical techniques for inducing nonunion in the lower third of the radius of adult dogs are also described. Results were evaluated by clinical, radiologic, and histologic examinations and by 99mTc scintillation. A total of 57 animals (41 electrically stimulated and 16 control animals) was used. Statistically significant data show activation of endochrondral ossification and bone union by electric stimulation.
