逆行拇指桡背侧岛状皮瓣修复拇指末节软组织缺损

目的 介绍以拇指桡背侧动脉为蒂的逆行岛状皮瓣在拇指末节软组织缺损修复中的应用.方法 应用逆行拇指桡背侧皮瓣修复拇指末节软组织缺损.结果 2004年1月至2007年6月,临床应用24例,切取皮瓣面积2 cm×2 cm～3 cm×4 cm.术后3例皮瓣出现静脉回流障碍,其中1例皮瓣远端1/3坏死,其余皮瓣均完全成活.随访6～24个月,拇指外观及功能良好,皮瓣两点辨别觉7～11 mm,平均9.3 mm.结论 逆行拇指桡背侧岛状皮瓣是修复拇指末节软组织缺损的一种良好方法.

Reconstruction of distal segment defect of thumb with reverse dorsal radial flap

Objective To introduce the application of reverse dorsal radial flap in reconstruction of distal segment defect of thumb. Methods From January 2004 to June 2007,24 eases of soft tissue defect with exposed bone or tendon at the distal segment of thumb were involved. The flap size ranged from 2 cm × 2 cm to 3 cm× 4cm. Results Venous congestion happened in 3 cases with one case of partial necrosis at the distal end of the flap. All the other flaps survived completely. The follow-up period was 6～ 24 months. The appearance and function of the thumbs were satisfactory. The 2-point discrimination was 7 ～ 11 mm(mean 9.3 mm).Conclusions Reverse dorsal radial flap is a good option for reconstruction of distal segment defect of thumb.
