Vascularised fibular grafts for reconstruction of extremity bone defects after resection of bone and soft-tissue tumours : a single institutional study of 49 patients.

AIMS: The aims of this study were to analyse the long-term outcome of vascularised fibular graft (VFG) reconstruction after tumour resection and to evaluate the usefulness of the method. PATIENTS AND METHODS: We retrospectively reviewed 49 patients who had undergone resection of a sarcoma and reconstruction using a VFG between 1988 and 2015. Their mean follow-up was 98 months (5 to 317). Reconstruction was with an osteochondral graft (n = 13), intercalary graft (n = 12), inlay graft (n = 4), or resection arthrodesis (n = 20). We analysed the oncological and functional outcome, and the rate of bony union and complications.
RESULTS: Five- and ten-year overall survival rates were 89% and 86%, respectively. Local recurrence occurred in two patients. Eight patients developed pulmonary metastases. Bone union was achieved in 44 patients (90%). Fracture occurred in six patients (12%), infection in three (6%), and nonunion in five (10%). The mean Musculoskeletal Tumor Society (MSTS) scores were as follows: osteochondral graft 70%; intercalary graft 73%; inlay graft 89%; and resection arthrodesis 83%.
CONCLUSION: Although associated with a relatively high rate of complications, each reconstruction method is useful, with a high rate of successful limb salvage and a good long-term functional outcome.
