Reconstruction of a Bone Defect (Malignant Bone Tumor) in the Diaphyseal Tibia Using Circular External Fixator with Trifocal Bone Transport (Distraction Osteogenesis)

Adamantinomas are rare bone tumors of unknown origin. They have low potential for metastasis and treatment consists of marginal resection. As they are usually located in the diaphyseal region of the tibia, resection leads to a bone defect. In this case we present a patient with adamantinoma located in the mid-diaphyseal region of the tibia. Following resection, the defect was reconstructed with bifocal transport using Ilizarov ring fixator. At the end of the trasportation of the segment, bone grafting and plate osteosynthesis was performed due to non union of the bone ends.
