Abstract: 【Abstract】〓Objective〓To investigate the clinical efficacy of unilateral producible external fixation apparatus for treatment of open tibia fracture with bone defect. Methods〓Twenty-one cases with fresh open tibia fracture (GustiloⅢB/C) with bone defect between June 2011 and June 2014 were included in this study and analyzed retrospectively. The surgical procedure was performed as follow: after one-stage debridement,.esquillectomy or elimination of heavily polluted bone tissue and repairing damaged blood vessel and nerve,.the unilateral producible external fixation apparatus was used to perform external tibia fixation. Then, operation of the superior extremity tibia osteotomy for bone-extension was done and bone transport operation began 2 weeks after operation..The external fixation apparatus was removed when bone got union. Results〓The average follow-up period was 18 months(range, 10 months to 3 years). Complete heal was achieved in 17 patients by one-stage operation. Three cases underwent local rotation flap and one case received thickness skin graft due to necrosis of skin flap..Complete union was achieved in all 21 cases. No refracture was observed after the removal of the external fixator, and the average healing time was 8 months.(range,.5 to 13). Conclusion〓Unilateral producible external fixation apparatus is an effective surgical approach for treating open tibia fractures by the way of esquillectomy, tibia osteotomy, bone transport for bone-extension.
