OBJECT An electrical field cathode (negative pole) has trophic and tropic effects on injured spinal cord axons in in vitro and in vivo models of sea lamprey, rodent, and canine spinal cord injury (SCI) and it improves functional outcome. A human oscillating field stimulator (OFS) was built, a Food and Drug Administration (FDA) exemption number was obtained,(More)
The authors report the case of patient with a lumbar vertebral body osteoporotic compression fracture who underwent percutaneous transpedicular polymethylmethacrylate (PMMA)-assisted vertebroplasty in whom extravasation of the cement into the spinal canal caused immediate neurological deterioration. Lateral lumbar radiography and computerized tomography(More)
We have studied the application of voltage gradients to injured spinal cord which enhanced regeneration of axons and reduced their retrograde degeneration after injury. This led to an implanted electronic device producing electrical fields sufficient to induce regeneration in both ascending and descending tracts of white matter (called oscillating field(More)
