An experimental double-blind study to evaluate the effectiveness of a constant current stimulator was performed on 30 young pigs that underwent a spinal fusion at the level of L5-L6. The group of animals with an active bone-growth stimulator showed a statistically significant increase of osteoblastic activity with bone formation.
