目的探讨应用趾背动脉供血的微型蹲甲瓣修复甲床缺损的方法及临床效果。方法自2012年1月至2016年1月，以趾背动脉供血的微型躅甲瓣修复12例拇指、7例示指、2例中指、2例环指甲床及背侧皮肤软组织缺损．缺损面积6mm×12mm～14mm×28mm。供区予直接缝合、全厚皮片植皮或带蒂皮瓣修复。结果术后足母甲瓣全部成活。随访6～48个月，23例患指指甲生长平整、光滑，外形饱满，功能恢复好。供区未见明显畸形，功能未受影响。结论游离移植趾背动脉供血的微型足母甲瓣是拇、手指甲床缺损美学修复的理想方法。

Objective To explore the surgical techniques and clinical effects of the mini wraparound flap supplied by the first dorsal digital artery for nail bed reconstruction. Methods From Jan 2012 to Jan 2016, the mini wrap-around flap supplied by the first dorsal digital artery was harvested to reconstruct nail bed defect, including 12 cases in thumb, 7 cases in the index finger, 2 cases in the middle finger and 2 cases in ring finger. The size of the defects ranged from （6 mm×12 mm）-（14 mm×28 mm）. The donor sites were directly closured, or covered with full-thickness skin grafts and pedicle flaps. Results All the flaps were survived. Patients were followed up for 6-48 months. Twenty-three cases were all satisfied with near-normal appearance and good function. No significant morbidity was observed at the donor site and the function was not affected. Conclusion Mini wraparound flap supplied by the first dorsal digital artery is an excellent method for entire or partial nail bed reconstruction.
