Minimally invasive plate osteosynthesis (MIPO) combined with distraction osteogenesis in the treatment of bone defects. A new technique of bone transport: a report of two cases.

摘要

This study reports two cases of fracture of the femur with segmental bone loss that were treated by a new technique of bone transport. A minimally invasive plate osteosynthesis (MIPO) bridge from the proximal to distal femur served as a fixation system. A separate Wagner distraction apparatus was used for distraction osteogenesis.After the transport segment docked with the bone fragment, it was fixed to the plate by a percutaneous screw fixation. The Wagner lengthening device was then removed. The total time of external fixation was significantly reduced.A satisfactorily functional result and bone segment regeneration was achieved. The external fixation index was 0.31 and 0.37 month/cm, and the limb length discrepancy was 0.9 and 1.2cm. The advantages of this technique include a decrease in the duration of external fixation, protection against refracture and earlier rehabilitation.
