A direct constant-current cathode caused bone to form at a site remote from any bone trauma in the medullary cavity of a rabbit tibia. The osteogenic response was current-dependent and the greatest bone respoose developed around cathodes delivering twenty microamperes of current. Excessive current (thirty microamperes or more) caused osteonecrosis. EIevation of voltage also caused bone destruction.
