Objective To introduce the surgical techniques and clinical results of repairing defects of the finger nail bed with free great toe dorsofibular nail flap transfer.Methods From December 2011 to February 2013,dorsofibular nail flap of the great toe based on the great toe fibular dorsal artery was applied to repair defects of the finger nail bed in 10 cases.These defects involved the thumb in 7 cases,the index finger in 2 cases,and the middle finger in 1 case.The size of the defects ranged from 8 mm × 12 mm to 13 mm × 21 mm.The donor sites were covered with full-thickness skin grafts.Results All 10 great toe dorsofibular nail bed flaps survived completely.Complete survival of the skin graft and primary healing at the donor site was seen in 8 cases.Necrosis at the edge of the skin graft occurred in 2 cases which was treated with dressing change and healed secondarily.Postoperative follow-up ranged from 9 to 23 months,with an average of 15 months.Nails that grew back at the recipient thumb or finger were smooth,shiny and plump in appearance.Walking function of the donor foot was not affected.There was no pain.Conclusion Transfer of the great toe dorsofibular nail bed flap is an ideal procedure for treatment of different types of finger nail bed defects.%目的 探讨游离(拇)趾腓背侧甲床皮瓣修复手指甲床缺损的方法及临床效果.方法 2011年12月至2013年2月,应用以(拇)趾腓侧趾背动脉为血供的(拇)趾腓背侧甲床皮瓣移植修复手指甲床缺损10例,其中拇指7例、示指2例、中指1例,缺损面积为8 mn× 12 mm～ 13 mn×21 mm.供区取全厚皮片植皮修复.结果 10例(拇)趾腓背侧甲床皮瓣全部存活,(拇)趾供区植皮8例Ⅰ期成活,2例植皮边缘少许坏死,经换药后瘢痕愈合.术后随访时间为9 ～ 23个月,平均15个月,拇指指甲生长平整、有光泽、外形饱满,供区行走功能无影响、无疼痛.结论 游离(拇)趾腓背侧甲床皮瓣是修复手指甲床缺损的理想方法.
