IN THE performance of interscapulothoracic amputation of the upper extremity, the sacrifice of a large amount of skin is at times necessary. These large defects pose a problem with regard to the matter of a satisfactory closure. Most surgeons have utilized the split thickness skin graft. Although such grafts are predominately successful, certain disadvantages of this type of closure are obvious. These disadvantages revolve about the following considerations: (1) the placement of a split thickness skin graft on an area which cannot be sufficiently immobilized, (2) the time consumed in preparing the skin, draping, cutting the skin grafts from the donor site and suturing them into the recipient site, (3) the addition of the granulating area of the donor site and (4) the resulting thinness of the thoracic wall covered in this fashion. An injury in this area readily may result in a communication with the thoracic cavity.
