Partial bone loss treatment using parietal bone transportation

Objective: This study describes the bone transportation technique for partial bone defect, and shows clinical and radiological results of a series of patients treated by using this method. Material and Methods: Nine patients with partial bone defect were treated (six tibia and three femur). Every patient had infection and nonunion. The initial procedure was to stabilize the bone, followed by a partial corticotomy on the healthy bone adjacent to the defect, in order to create a fragment to be distracted. This fragment was fixed by olive wires, which were conected to the thread rod. We used fibula transport for tibial lateral defect in two patients. The latency time, speed and rhythm of distraction were the same as approved by Ilizarov. Results: Infection and nonunion were resolved, and the bone gap was filled in all cases. The most frequent problems were skin infection at the pin site and hypotrophy. Conclusion: The partial bone defect treated by parietal bone transport was an effective soluction for all patients with infection and nonunion, filling the gap in all cases.
