目的 探讨应用第2足趾末节游离移植再造示中环指指尖部缺损的方法 及临床疗效.方法 2008年3月-2010年12月,对156例168指示中环指指尖部缺损患者,采用第2足趾末节游离移植进行再造.结果 再造156例168指均成活,仅9例于术后24～48h发生血管危象,经拆除部分缝合线、放血治疗处理及手术探查后均成活,无再造指尖坏死发生.术后随访134例142指,随访时间3个月～2年,再造指尖手指外形恢复良好,大小与正常指尖相似,指甲面积较大,指纹生长良好,指腹皮肤两点辨别觉4～6mm.供区足部行走功能无明显影响.结论 应用第2足趾末节移植再造示中环指指尖,不仅可获得良好的外观,而且具有极高的成活率,供区损伤小,患者容易接受,是一种较理想的修复方法.

The curative effect reconstruction of fingertips by transplantating distal pan of the second toes

Objective To explore of the fingertips defect method and its curative effect of reconstruction by transplanting distal part of the second toes. Methods From March 2008 to December 2010, 168 fingertips defect with fingers in 156 cases, fingertips repair to distal part of the second toes. Results All 168 reconstituted fingertips in 156 cases survived.9 fingers occurred vascular crisis between 24 and 48 h after operation. The vascular crisis was released and the fingers survived through taking out some stitches, bloodletting and operation ascertainment, thanatosis of the fingertips Was absent.Followed-up 142 finger tips in 156 cases from 3 months to 9 years,shown to be satisfactory in outward appearance and recovery of sensory and motor function, similar to normal fingers, two point discrimination found to be between 4- 6mm. there are no influence for foot with injured toe. Conclusion It is reconstruction of fingertips by grafting distal part of the second toes. Besides favorable outward appearance recovery, more than the high survival rate on the basis of the smaller damnification in donor site.
