摘要
目的探讨以指动脉远侧指间关节皮支为蒂指侧方岛状皮瓣修复同指指端软组织缺损的临床效果。方法2009年6月至2010年3月，对15例15指手指远侧指问以远的指端缺损的患者，采用以指动脉远侧指间关节皮支为蒂指侧方岛状皮瓣转移修复，术中切取皮瓣范围1．2cm×0．8cm～2．0cm×3．0cm，供区取前臂全厚皮片移植修复。结果15例15指术后获得随访10例10指，时间为6-12个月，皮瓣和移植皮片全部顺利成活，皮瓣质地柔软，外观满意，颜色与周围皮肤接近，顺行推进岛状皮瓣的两点辨距觉为5～6mm，逆行岛状皮瓣的两点辨距觉为7～10mm，远侧指间关节屈伸活动无明显障碍。手功能ATM法评定，优8指，良1指，可1指。结论应用该皮瓣修复指端软组织缺损，不损伤指动脉和指神经，简化了传统的指根部岛状皮瓣的手术，是一种较好的方法。
Objective To investigate the repair of soft tissue defect at finger tip with square island flap pedicled with skin perforator of digital artery on the distal interphalangeal joint （DIP）. Methods From Jun. 2009 to Mar. 2010, 15 cases with soft tissue defects at 15 fingers tip were treated with this island flaps. The flap size ranged from 1.2 cm x 0. 8 cm to 2.0 cm x 3.0 cm. The defects at donor sites were covered with skin grafts from forearm. Results All the flaps and skin grafts survived. 10 fingers in l0 cases were followed up for 6-12 months. The color, texture and contour of the flaps were good. The two- point discrimination distance was 5-6 mm on the directed island flaps, and 7-10 mm on the reverse island flaps. No obvious functional problem was found in DIP motion. The hand function was assessed as excellent in 8 fingers, good in 1 finger and medium in 1 finger. Conclusions The main artery and nerve will not be sacrified when the island flap is used. The operative procedures are easily performed for the treatment of fingertip skin defect.
