指端部分缺损的形态学修复

Reconstruction of partial defects at the end of the fingers

目的研究应用吻合血管的游离足趾组织移植急诊修复拇指及其他手指指端部分缺损的治疗方法。方法对19例21指指端部分缺损者，应用拇趾趾腹皮瓣、第2趾趾腹皮瓣、第2趾趾甲皮瓣、拇趾半侧趾甲皮瓣、第2趾半侧趾甲皮瓣游离移植进行再造。结果19例21指游离皮瓣、趾甲皮瓣全部成活，术后经过3～6个月的随访，患指指腹饱满并具有指纹，外观良好，两点分辨觉为4～6mm。结论对于手指指端部分缺损，应用上述手术方法进行再造，可达到良好的修复效果。

Objective To study the reconstruction of partial defects at the end of the thumbs and other fingers with microsurgical free toe flaps. Methods 21 partial defects （ 19 cases） at the end of thumbs and other fingers were reconstructed with microsurgical free toe flaps taking from the corresponding toe part. Results All the free flaps survived. The patients were followed up for 3 - 6 months. The aesthetic and functional results were both satisfactory. The two-point-discrimination distance was 4 - 6 mm. Conclusions The microsurgical free toe flaps have good therapeutic effect for the reconstruction of partial defects at the end of the fingers.
