应用改良掌背皮瓣修复手指中、远节皮肤缺损

The clinical application of improved dorsal metacarpal flap in repairing of the middle and distal segment of finger skin defects

目的:报道改良掌背皮瓣修复手指中、远节皮肤组织缺损的临床应用。方法:2011年3月-2014年9月,采用改良掌背皮瓣治疗各指中、远节皮肤缺损8例。将掌背皮瓣的旋转点位于指蹼以远、近节指间关节近1.0cm之间。皮瓣切取面积:2.0cm×2.0cm^5.5cm×3.5cm。结果:7例皮瓣全部成活,1例皮瓣远端部分坏死经换药等处理瘢痕愈合。术后平均随访6个月,皮瓣外形、色泽、血运良好,厚薄适中,两点辩别觉1.1~2.5cm手部功能满意。结论:改良掌背皮瓣(将皮瓣旋转点向远端推移至指蹼以远)修复手指中、远节皮肤组织缺损的临床疗效良好。

Objective To discuss the clinical application of improved dorsal metacarpal flap in repairing of the middle and distal segment of finger skin defects. Methods Summary of 8 cases with skin defects in the middle and distal segment of finger were repaired with improved dorsal metacarpal flap since March 2011 to September 2014.The rotation point of the dorsal metacarpal flap located in Webbed finger refers to Far and near section between nearly 1cm of the interphalangeal joint. The area of the flap was cut out is from 2.0cm ×2.0cm-5.5cm ×3.5cm. Results 7 cases flaps were all survived,one distal portion of the flap necrosis was scar healed by dressing and other treatment.Good appearance,colour and lustre,blood supply of the flap, medium thickness,two-point discrimination 1.1cm to 2.5cm and satisfaction of hand function have been seen after an average followed-up of 6 months. Conclusion There was a good clinical efficacy improved dorsal metacarpal flap in repairing of the middle and distal segment of finger skin defects
