The electrical current has been applied for fracture healing. Bared tip, one and half centimeter in length of a multistrand stainless-steel wire insulated with Teflon was inserted into the bone marrow as a cathode and the anode was fixed on the skin. The power pack with 9 volt battery modified to discharge a constant current of 10 microamperes inspite of variable resistence was connected in between both poles. All the patients were sustained either of the fracture of the femur or the tibia.Five patients with non-union, five with delayed union and four with fresh fracture were included in this series. Complete healing of fracture was obtained in thirteen out of fourteen cases. Electrical current thus applied might be said to enhance bone formation and is promising for the treatment of fractures, especially for non-union or delayed union.
