An external fixation device (100) in combination with an electrical stimulus generator (160) for use in the promotion of osteosynthesis in the healing of a bone fracture. Implemented as follows: using a standard external fixation device (160); fix the site of the bone fracture by inserting a first and second pair of fixation pins (112, 114, 122, 124) on each side of the fracture site; fixing at least one cathode (142) in electrical contact with the bone adjacent to the fracture site; and the cyclically applying a voltage between the fixation pins (112, 114, 122, 124) and the cathode (142). Whereby, current flows in a defined cycle from cathode (142) to one of the two pairs of fixation pins (112, 114, 122, 124), then from one pair of pins to the other, then from the cathode (142) to the other pair of electrodes. |
