目的介绍第五掌骨尺侧逆行筋膜皮瓣修复小指软组织缺损的手术方法。方法2000年～2002年,对12例患者应用第五掌骨尺侧逆行筋膜皮瓣,分别修复小指掌侧、背侧和尺侧软组织缺损。皮瓣设计以第五掌骨头尺侧与豌豆骨连线为轴线,其蒂部转折点在掌指关节以近0.5cm～1.0cm处。皮瓣面积最大6.0cm×3.0cm,最小2.5cm×1.5cm。结果12例皮瓣全部成活,术后随访5～7个月,外形美观,质地柔软,两点辨别觉8mm～12mm。结论第五掌骨尺侧逆行筋膜皮瓣具有血供可靠、切取方便、质地良好等优点,是修复小指软组织缺损的良好方法。

Objective To introduce a reversed ulnar fasciocutaneos flap of the fifth metacarpal bone for repair soft tissue defect of the little finger.Methods From May2000to January2001,twelve patients with soft tissue defects in palmar,dorsal and ulnar part of the little finger were treated with the reversed ulnar fasciocutaneous flap of the fifth metacarpal bone.Axial line of flap was the line from the head of the fifth metacarpal bone to the pisiform one.It was0.5cm～1.0cm between the pedicle and the soft tissue defect.The largest size was6.0cm×3.0cm,the smallest was1.5cm×1.5cm.Results All flaps survived,following-up for 5～7months they had good appearance and the sensation with2-PD was8～12mm.Conclusion The reversed ulnar fasciocutaneous flap of the fifth metacarpal bone is a reliable flap with its easy dissection and good texture in repair soft tissue defect of the fifth finger.
