The method of investigation was histological with filling of the vessels with ink-gelatin mixture. Totally 36 exostoses were studied. The vast majority of them arose after fascio-and myoplastic amputation and myodesis with the excessive muscle tension. The causes of the appearance of exostoses were the excessive tension of the muscles created during the plastic surgery, and their contracture contractions in the postoperative period. There was a resorption of the cortical diaphyseal plate along the inner and outer surfaces, intraosseous circulation and reparative osteogenesis were disrupted.
