应用单侧双臂外固定支架同期行延长与加压治疗胫骨骨不连伴骨缺损

Unilateral Double-arm External Fixator for the Treatment of Bone Nonunion and Defection of Tibia Simultaneously with Lengthening and Compression

目的探讨胫骨骨不连伴骨缺损的有效治疗方法。方法对24例胫骨骨不连伴骨缺损患者采用单侧双臂外固定架加压固定骨断端，同期行截骨延长术，在骨断端加压固定的同时重建肢体长度。结果24例胫骨骨不连伴骨缺损患者最终均达到骨性愈合。骨缺损长度延长3～5cm，平均3．8cm；骨愈合时间6～14个月，平均8．5个月。结论应用单侧双臂外固定支架同期行延长与加压治疗胫骨感染性骨不连伴骨缺损，能有效促进感染与骨缺损的愈合，同期行小切口截骨延长不仅有效重建了肢体长度，达到肢体长度的均衡，并且避免了二次手术，大大地降低了治疗费用。

Objective To explore the effective procedure for the treatment of bone nonunion and defection of tibia. Methods 24 patients of bone nonunion and defection of tibia who were treated by unilateral double-arm external fixator simultaneously with lengthening and compression were reviewed. Results All 24 patients achieved bony union. All patients were cured by lengthening tibia 3.8 centimeters in average（3-5 centimeters） without any complication. Average healing time was 8.5 months（6-14 months）. Conclusion Unilateral double-arm external fixator simultaneously with lengthening and compression is an effective way which facilitate the cure of infection and bone defection, avoiding secondary operation and extending the length of lower limb as well as cutting down the medical cost remarkably.
