BACKGROUND: Advances in oncologic treatment modalities and wide resection have made limb salvage procedures in calcaneal malignancy increasingly possible. However, reconstructions of the calcaneal remain a major surgical challenge because of the rarity and specific anatomy of this condition. METHODS: we retrospectively reviewed five patients who had primary calcaneal malignancy and underwent total calcanectomy and reconstructions with the distally pedicled osteocutaneous folded fibular flap between 2001 and 2007. The diagnoses included chondrosarcoma in 2, Ewing's sarcoma in 2 and osteosarcoma in 1. Three tumors were classified as stage-II B lesions, one as I A and one as II A. Wide resection margins were achieved in all patients. The patients were followed up for a mean of 50.4 months (range, 32-76 months). Patients were examined clinically and radiographically and were assessed functionally with Musculoskeletal Tumor Society (MSTS) score and American Orthopaedic Foot and Ankle Society (AOFAS) score. RESULTS: Four patients had no evidence of disease, and lung metastasis was found in one patient who was alive with disease. No local recurrence occurred in this series. At latest evaluation four patients had no evident limp or limitation of daily activities and one patient had mild limp. The average MSTS 93 score and AOFAS score were 83.2% and 86.4% at the last follow-up, respectively. All fibular flaps survived and bone unions achieved successfully. Fibula hypertrophies were seen in three patients. The overall mean time for bone union was 6.2 months. The mean time to full weight-bearing was 8.6 months. The average two-point discrimination was 2.3 cm at the time of final follow-up. Two patients had surgery-related complications including hematoma in 1 and skin margin necrosis in 1. CONCLUSIONS: Following the wide resection of calcaneal malignancy, biological reconstruction using distally pedicled osteocutaneous fibular has proven to be a successful limb salvage procedure, offering satisfactory local tumor control and functional restoration of the lower extremity function.
