携趾动脉的第2趾复合组织块移植修复与再造手指部分缺损

Transplantation of the second toe composite tissue blocks carrying toe artery to repair and reconstruct finger defects

目的总结采用携趾动脉的第2足趾复合组织块移植修复与再造手指部分缺损的手术方法及临床效果。方法收集我院自2011年1月至2014年1月手指部分缺损病例,对其中9例患指采用带趾动、静脉及趾神经的第2趾复合组织块移植修复与再造。结果手术均获得成功,经6个月～2年(平均10个月)随访,受创指间关节活动度平均约为60°,指腹两点分辨觉为7～10 mm,外形良好。结论以第2足趾为供区的复合组织块是修复与再造手指部分缺损的较佳方法之一,且单纯游离趾动脉具有对供区创伤小,皮瓣切取简单等优点。

Objective To report the surgical methods and clinical effects of finger defect repair with the second toe composite tissue blocks carrying toe artery .Methods Nine cases of fingers defects were repaired and reconstructed with transplantation of the second toe com -posite tissue blocks in our hospital from January 2011 to January 2014 .Results All transplanted tissue survived and the mean follow-up peri-od was 10 months (0.5~3 years).An average of 60 degrees of range of motion of interphalangeal joint was achieved .The two-point discrim-ination was 7~10 mm,and the appearance of repaired fingers was excellent .Conclusion The transplantation of the second toe composite tis-sue block is the optimal way to repair finger defect ,and it is easy to transplant with less trauma for the donor site .
