Clinical literature has indicated that non-operative treatment is the treatment of choice for clavicular fracture except such example as non-union. Since 1981, 17 patients with a clavicular fracture have been treated by internal fixation with one or two modified threaded Kirschner wire. The patients' age ranges from 14 to 73 years, The operative indication was adapted to the patients with largely displaced fragments in spite of conservative therapy, neurovascular impingement of upper extremity, delayed unions, and with the inability to tolerate prolonged immobilization. Threaded Kirschner wire was modified with minor change which consists of more shortened part of thread so as not to break easily in it, and of bipointed end.On technical procedure threaded part is anchored on the cortex of distal end after penetrating the proximal fragment backward through medullary canal.All fractures healed with complete union. None of migration of wires but one which was found to be technical failure, and no bursitis were seen. The merits of this method are presumed to be easy utility and flexibility similar to original Kirschner wire, and to be immobility due to threaded part.
