Abstract 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.
