BACKGROUND: Tumor-bearing frozen autografts have been used for reconstruction of bone defects after resection of bone tumors. In the present study, outcomes and complications of reconstruction using frozen autografts were assessed to determine indications for this procedure in patients with metastatic bone lesions. PATIENTS AND METHODS: Twenty-two patients were treated with reconstruction using frozen autografts. The surgical technique involved excision of the bone lesion, curettage, freezing in liquid nitrogen, thawing and reconstruction. RESULTS: Limb function was evaluated in 11 patients; wa found excellent in 10 patients and good in 1 patient. Five-year overall survival and disease-free survival rates were 46.7% and 26.3%, respectively. Five-year fracture-free survival and recurrence-free survival rates were 79.9% and 100%, respectively. Complications were observed in 6 patients and included fractures (4), deep infection (1) and osteoarthritis (1). CONCLUSION: Reconstruction using frozen autografts is a beneficial treatment option in patients with long expected survival or complete cure of the primary cancer. Copyright
