Methods and devices for treatment of osteonecrosis of the femoral head with core decompression include a dowel adapted for placement into a core decompression channel of a femoral head. A cathode at the distal end of the dowel provides electrical stimulation of bone growth in the femoral head. A method of treating osteonecrosis of the femoral head involves placing a dowel having a cathode thereon into a core decompression channel of a femoral head in a state of osteonecrosis. Electrical current is supplied to the cathode for electrical stimulation of bone growth in the femoral head. |
