RESUMO
Musculoskeletal tumours of the lower limbs especially malignant tumours are not common. The fibula is the site of primary bone tumours as reported in 2.4% of lower limb tumours with the proximal third being more frequently involved than the distal segment. Osteosarcoma is the most common primary malignant bone tumour of nonhaematopoietic origin, with distal fibular involvement in 0.47% of patients. The advances in imaging techniques and neo-adjuvant chemotherapy have now made it possible to accurately define the extent of tumour and plan limb salvage with tumour resection. The purpose of this case report is to highlight the successful outcome of limb salvage procedure with a five year follow up in an 11-year old boy with distal fibular osteosarcoma. Limb salvage surgery with distal fibulectomy and retention of the foot are a good alternative to radical amputation.
