Structure of the osseous callus formed under electric stimulation. An experimental histological study

The study tried to evidence histologically, histometrically and mechanically the comparative qualities of the osseous callus experimentally formed in dogs and rabbits under the influence of an electric stimulation. The materials were decalcified or polished, and the collagen network and the Haversian systems analysed in the callus. The tearing strength in kg-power on the surface unity of the osseous tissue was measured using the EDZ 20 apparatus. The results indicated that the osseous tissue formed under electric stimulation had a structure and a tearing strength similar to that of controls, and that the consolidation time of fractures is reducing.
