ABSTRACT
The management of upper extremity gunshot wound with soft tissue and bone injuries remains a remarkable problem and often requires sophisticated reconstructive strategies.There are limited reconstructive options for the treatment of segmental bone defects of the upper extremity exceeding 6 cm in length, especially when associated with soft tissue loss. Among the limited treatment options, the osteoseptocutaneous fibular transplantation is well established. The vascularized fibula flap has become a major tool in upper limb reconstruction but still is an uncommon procedure and continues to challenge reconstructive surgeons.In this paper, we report a complex combined skeletal and soft tissue involvement of an upper extremity case successfully treated with fibula osteoseptocutaneous free flap. The bone defect measured 12 cm. In severe injuries of the upper extremity, free transfer of the fibula flap not only provides replacement of the resulting composite defect but may also offer salvage of the extremity.

BACKGROUND: Complete traumatic upper extremity avulsions are an infrequent but devastating injury. These injuries are usually the result of massive blunt trauma to the upper limb. Intact issue from amputated or nonsalvageable limbs may be transferred for reconstruction of complex defects resulting from trauma when the indications for replantation are not met. This strategy allows preservation of stump length or coverage of exposed joints, and provides free flap harvest for reconstruction without additional donor-site morbidity. METHODS: A retrospective review at São João Hospital was performed on seven patients who had undergone immediate reconstruction with forearm free fillet flaps between 1992 and 2007. RESULTS: There were six men and one woman, with patient age ranging from 17 to 74 years (mean, 41 years). Amputation sites were at the humeral neck (n = 1), at the humeral shaft (n = 5), and below the elbow (n = 1). The area of the forearm free fillet flap skin paddle was 352.14 +/- 145.48 cm (mean +/- SD). The two major complications were the flap loss and the patient death on postoperative day 3 in other case. The postoperative course in the remaining five cases was uneventful with good healing of the wounds. Minor complications included two small residual defects treated by split-thickness skin grafting and one wound infection requiring drainage and revision. CONCLUSIONS: The forearm free fillet flap harvested from the amputated limb provides reliable and robust tissue for reconstruction of large defects of the residual limb without additional donor-site morbidity. Microsurgical free fillet flap transfer to amputation sites is valuable for achieving wound closure, improving stump durability, and maximizing function via preservation of length.
