带血管的腓骨移植修复四肢骨大段骨缺损的临床体会

目的 探讨一种修复四肢骨大段骨缺损的手术新途径 ,以提高植骨存活率。方法 自1988年来 ,对31例骨缺损范围6～14cm病例 ,采用带血管的腓骨移植方法 ,移植腓骨8～18cm,随访8个月～12年。结果 29例均在2～4个月愈合 ,平均愈合时间2.5个月。结论 带血管腓骨移植是“活骨移植” ,骨愈合过程与骨折相似 ,改变了传统骨移植需经过漫长的“爬行替代”过程 ,是修复大段骨缺损的最佳方法。

Objective To search for a new pathway to treat large bone defect and improve survival rate of bone graft. Methods From 1988, 31 patients who had bone defect of 6 to 14cm were transplanted with vascularized fibula, and followed up for 8 months to 12 years. Results 29 of 31 patients healed after 2 to 4 months, and the mean time was half and two months. Conclusion Vascularized fibula transplantation was a 'living-bone transplantation'. Its healing procedure was similar with fracture, and it was appropriate to treat large bone defect.
