ABSTRACT:
A cathode assembly for use in conjunction with an internal fracture fixation device for the purpose of stimulating osteogenesis (bone growth) within a fracture site. The assembly is comprised of a carrier made from an implantable non-conductive material containing a cathode with a conductive cable leading from the cathode to the patient's electrical bone growth stimulating apparatus. The carrier is mountable on the fixation device for maintenance at the desired location. In a preferred embodiment, a sleeve carrier contains a plurality of ports which allow the current generated by the stimulating device to flow through the cable to the cathode where it is evenly distributed through the ports to the bone tissue. The sleeve can be slipped onto a fracture fixation device, such as a compression hip screw, and is located on the device such that the sleeve containing the cathode lies across the fracture site.
