Partial volar amputations of the entire thumb pulp require soft tissue coverage that provides not only padding and protection for exposed bone and tendons, but also restoration of discriminative sensation. A modification of the radial sensory innervated cross finger flap from index to thumb is described, which includes separate reinnervation of the flap by repair of the dorsal sensory branch of the index radial digital nerve to the ulnar digital nerve of thumb. The anatomical basis for this flap is discussed and two example cases presented. Sensory reinnervation is rapid and does not require cortical reorientation.
整个拇指指腹的部分掌侧截肢需要软组织覆盖，这不仅能为暴露的骨骼和肌腱提供衬垫和保护，还能恢复辨别性感觉。本文描述了一种改良的从示指到拇指的桡侧感觉神经支配的交叉手指皮瓣，其中包括通过将示指桡侧指神经的背侧感觉支修复至拇指尺侧指神经来单独对皮瓣进行再神经支配。讨论了该皮瓣的解剖学基础并展示了两个病例。感觉再神经支配迅速，且不需要皮质重新定向。
