The free vascularized fibular graft (FVFG) to the tibia was first described by Taylor et al in 1975. 1 Since then, the operation has evolved to include transfer of adjacent muscle, and in 1983 Chen and Yan described an osteocutaneous flap. 2 These advancements have provided a limb-sparing option to those patients once destined for amputation. Indications for these procedures now include trauma, chronic osteomyelitis, wide resection of malignant tumor, and pseudoarthrosis of long bones.
3Prior to the advent of these procedures, complex fractures of the tibia were treated with autologous, nonvascularized cancellous bone grafting. Nonunion and complication rates were high, often leading to delayed amputation. Nonvascularized fibular autografts also showed high complication rates and particularly high rates of nonunion and stress fractures. Attempts to reduce these complications led to the proposal for vascularized grafts.

AbstractBackground The use of free vascularized fibular graft (FVFG) for proximal and midshaft tibial reconstruction is well documented in the literature. However, literature documenting distal tibial and proximal ankle reconstruction using this technique is lacking. The purpose of this case report is to demonstrate the osteocutaneous fibular free flap as a viable limb-sparing option to patients who previously required amputation in similar circumstances. Methods The patient is a 39-year-old man who sustained a traumatic distal tibial pilon fracture. He underwent open reduction and internal fixation, which was complicated by osteomyelitis requiring multiple debridements and ultimately, resection of necrotic tissue. The resulting distal tibial defect measured 12 cm, including the talus. In an attempt to salvage the extremity, an FVFG was performed using the contralateral fibula. The harvested fibula was inserted proximally into the intramedullary canal of the tibia and impacted distally into the talar dome. Results To date, the patient's postoperative course was notable for minor wound healing issues which resolved. Postoperative computed tomography confirmed fusion, allowing for weight-bearing and removal of the external fixator. Conclusion Reconstruction of distal tibial defects with ankle involvement is a challenging operation for orthopedic and plastic surgeons. We describe a case in which a 12 cm tibial defect in conjunction with a talar defect was successfully reconstructed with a free vascularized fibular graft. We believe that this is a safe and viable option for those wishing to avoid amputation.
