Salvage of amputation stumps by secondary reconstruction utilizing microsurgical free-tissue transfer.
During a 2-year period, 15 lower and upper extremity amputees were treated by microsurgical free-tissue transfer in an effort to salvage their amputation stumps. Salvage of length and restoration of contour to aid in prosthetic rehabilitation were the two main indications for reconstruction. Included in the 15 transfers were 3 scapular free flaps, 11 latissimus dorsi musculocutaneous flaps, and 1 groin flap. Thirteen of the patients in this group were refitted with prostheses following reconstruction and did well with no pain or skin breakdown of the resurfaced stumps. The follow-up period on these patients averaged 16 months. One patient, in whom the flap succeeded, underwent stump soft-tissue revision and myodesis. One patient, in whom the flap failed, continued to develop recurrent ulceration in his stump. This clinical experience followed an extensive laboratory study of 12 above-knee amputation patients using noninvasive Doppler ultrasound measurements to determine weight-loading and interface-pressure distribution between the stump and the socket of the prostheses and their relation to stump length and circumference.
