Microsurgical free flap transfer to amputation sites: indications and results.
A series of microsurgical free flap reconstructions to amputation stumps of the upper as well as the lower extremities was reviewed in 7 male and 2 female patients. Indications included preservation of length after trauma in 6 patients and cure of local infection in 2 patients. In 1 patient an extensive defect after resection of a recurrent shoulder sarcoma required use of a complete arm fillet free flap for tumor reconstruction. Microvascular free flaps used included four scapular flaps, two fillet flaps from the amputated extremity, one anterolateral thigh flap, and one lateral arm flap. Seven of 9 patients were fitted with a prosthesis and underwent occupational therapy resulting in ambulatory and improved functional status. Microvascular reconstruction is indicated in emergency settings as well as for elective reconstruction of amputation sites. Using uninjured "spare parts" of the amputated extremity should be considered. Elective reconstruction is performed preferably with free flaps based on the subscapular vascular system.
