Microvascular Composite Tissue Transfer for the Management of Type IIIB and IIIC Fractures of the Distal Leg and Compound Foot Fractures

ABSTRACT

Patients who sustain high-energy, compound fractures with severe contamination and soft tissue loss, face high rates of delayed union, nonunion, infection and, in some instances, amputation. The authors reviewed 18 patients with compound foot fractures and IIIB and IIIC tibial fractures. All patients were treated by early free-flap coverage and simultaneous bone reconstruction. Corticocancellous bone grafting, composite osteocutaneous free flaps, or bone transport techniques were utilized, as required. Bony union was achieved in all cases; rehabilitation and return to work occurred within 12 to 18 months, with no major complications.

The authors believe that the reconstruction ladder usually followed should be altered in certain cases in which severe periosteal stripping and soft-tissue contamination necessitate distant free composite tissue transfer, particularly those cases involving the distal third of the leg and foot. Simultaneous reconstruction is superior to other methods of wound management in providing early coverage of extensive wounds, a barrier against bacterial contamination, prevention of osteomyelitis, and enhanced union of the fractures.
