Effect of Electrical Stimulation on the Tensile Strength of the Porous Implant and Bone Interfac

Abstract

The effect of electrical stimulation upon the direct tensile strength of the interfacial union between porous calcium aluminate implants (100 to 200μ diameter pores) and bone was studied in the femurs of rabbits. After about 4 weeks of implantation the tensile strength of the electrically stimulated specimens was approximately two times that of the nonstimulated ones. This indicates that electrical stimulation increased the rate of new bone formation under the experimental conditions.
