In covering amputations of fingertips several methods, including free grafts and local flaps have proven useful. When the amputation is at a more proximal level near the cuticle closure of the wound is often accomplished by further shortening of the distal phalanx and eradication of the nail matrix in order to avoid a claw-like deformity of the nail. This results in a unpleasant stump of poor prehensile quality. Therefore attention is called to the distal thenar flap which offers all the advantages of the palmar flap e. g. adequate subcutaneous tissue for reconstruction of a fingertip, good texture and colour match and a great potential for recovery of sensation. To avoid permanent stiffness of the PIP joint the flap is fashioned well distally on the thenar eminence with the base on the radial side. Immobilisation is secured by means of a plaster cast with the thumb in full palmar abduction and the MP joint of the recipient finger in full flexion. This leaves the PIP joint in but moderate flexion. The base of the flap is severed at two weeks.
在覆盖指尖截肢创面时，包括游离皮片移植和局部皮瓣在内的几种方法已被证明是有用的。当截肢部位更靠近近端时，靠近角质层的伤口闭合通常通过进一步缩短远节指骨和切除甲床来完成，以避免指甲出现爪状畸形。这会导致残端外观不佳且抓握质量较差。因此，人们开始关注小鱼际远侧皮瓣，它具有掌侧皮瓣的所有优点，例如有足够的皮下组织用于重建指尖、质地和颜色匹配良好以及感觉恢复潜力大。为避免近端指间关节（PIP）永久僵硬，皮瓣在小鱼际隆起处向远端精心设计，基部位于桡侧。通过石膏固定，拇指完全掌侧外展，受区手指的掌指关节（MP）完全屈曲，从而使PIP关节保持适度屈曲。两周后切断皮瓣基部。
