[ traumatic dislocation of the trapezio metacarpal joint about 5 cases]

The high voltage electrical bums cause an exceedingly high rate of morbidity resulting from the massive necrosis of deeper structures often necessitating major limb amputations. The authors report two rare cases of high voltage electrical burns occurring accidentally with a 49 and 19 year old men after an indirect contact with a high voltage line. These high voltage electrical burns caused massive necrosis and extended necrosis m the upper limb requiring the recourse to a disarticulation the shoulder. The indications and the operative techniques used are discussed
