title: Reconstruction of Large Diaphyseal Defects of the Femur and the Tibia with Autologous Bone.
abstract: Post-traumatic segmental bone defects of the femur and the tibia above the critical size require special attention because conventional bone grafts result in high rates of nonunion. The biological and biomechanical aspects of this challenging surgery, as well as ongoing refinements to achieve mechanically stable bone healing with correct bone alignment are reviewed. Choosing the best appropriate method is mainly dependent on both the location and etiology of the bone defect. Three patients with successful bone reconstruction using two-stage reconstruction with cancellous bone graft, double-barrel free vascularized fibula transfer and distraction osteogenesis are described. Advantages and disadvantages of these methods are discussed in accordance with recent literature.
