Abstract
A screw for use in stimulating bone growth, tissue healing and/or pain control. The screw includes an elongate shaft having a length extending between opposite ends, an exterior surface and a screw thread formed on the exterior surface of the shaft and extending along at least a portion of the length. The shaft has an electrically conducting portion and an electrically insulating portion. The screw also includes a head adjacent one end of the shaft for engaging the screw to rotate the screw and thereby drive it into bone. The screw includes an electrical conductor electrically connectable to the shaft for conveying current through the shaft to the bone through the conducting portion of the shaft.
