The nowadays accepted principles of the treament of open leg fractures are discussed. The open character of the lesion multiplies the possibilities of complications. In the present paper the complications of the bone recovery are not dealt with, only the complications observed in the soft parts and the possibilities of their treatment are analysed by the authors. According to the severity of the soft parts complications free transplantation of semi-thick skin, pedicle flap plasty, double-end graft plasty, crossed flap grafting, as well as the primary and secondary variations of these methods are used by the authors. The satisfactory results obtained with these methods even in spite of the complications are pointed out by the authors.
