桥式血管吻合游离背阔肌骨皮瓣移植治疗胫骨缺损五例分析

Transplantation of free latissmus dorsi osteocutaneous flap using bridge-like vascular anastomosis in treatment of tibial defect：5-case report

应用桥式血管吻合游离背阔肌骨皮瓣移植对5例胫骨缺损患者（年龄24～46岁）进行修复治疗。骨皮瓣全部成活，胫骨缺损全部愈合。术后随访1．5～4．5年（平均2．6年），无明显的供区功能障碍，减轻了对供区的损伤。此技术适宜修复伤肢组织缺损仅有1条主要动脉者，且不损伤健侧小腿胫后动脉。

From September 2002 to May 2006, five patients （ age range, 24 to 46 ; mean, 32） with tibial defect underwent transplantation of free latissmus dorsi osteocutaneous flap using bridge-like vascular anastomosis. All the osteocutaneous flaps survived without any serious complications, and tibial defects were improved completely. After 1.5 to 4.5 years＇ follow-up （ mean, 2.6）, no remarkable dysfunction was found at donor sites, and local injury was reduced. This study indicates that transplantation of free latissmus dorsi osteocutaneous flap using bridge-like vascular anastomosis might be useful in leg reconstructive surgery if only one vessel is remained.
