Summary:Segmental tibial bone loss, specifically in the setting of high-energy trauma, presents a challenging problem to the treating orthopaedic surgeon. These injuries are often complicated by tissue loss, poor wound healing, and infection. Many techniques of reconstruction have been advocated from bone grafting to bone transport. Transport can accomplished using Ilizarov frames, monolateral external fixators, and intramedullary devices. Although transport over an intramedullary device offers the advantage of rigidity and controlled alignment, many authors consider prolonged external fixation and history of pin tract infection to be contraindications to this technique. To our knowledge, bone segment transport used in combination with locking plate fixation has not been described for the treatment of tibial bone defects. We describe two cases of bone transport using a combination of locked plate fixation and a monolateral external fixation frame for large tibial bone defects. This technique allows for easy correction of length and alignment, stable fixation, facilitates quicker, and easier frame removal and also allows for compression of transported segment at the time of docking.
