Four types of the reverse digital artery flap--standard, extended, and innervated standard and extended--were developed for 52 finger defects. The arising pattern of the dorsal branch which was included in the innervated flap was studied and classified in cadaver dissections. Topographically, the described "Lai's line" is a useful guide to locate the underlying digital artery. Refinements in flap design and surgical technique resulted in favourable functional and cosmetic results. The average two-point discrimination of the reconstructed fingertip was 6.8 mm and 3.9 mm in the noninnervated and innervated flaps, respectively. This versatile flap is an ideal and reliable option for one-stage reconstruction of various finger defects.
我们为52例手指缺损设计了四种类型的逆行指动脉皮瓣，即标准型、扩展型、带神经的标准型和扩展型。通过尸体解剖研究并分类了带神经皮瓣中包含的指背支的发出模式。从局部解剖学角度来看，所描述的“赖氏线”是定位指动脉的有用标志。皮瓣设计和手术技术的改进带来了良好的功能和外观效果。非带神经皮瓣和带神经皮瓣重建指尖的平均两点辨别觉分别为6.8毫米和3.9毫米。这种多功能皮瓣是一期修复各种手指缺损的理想且可靠的选择。
