Blood supply to the index finger is maintained through volar (palmar arch) and dorsal (intermetacarpal arteries) vascular networks. In traditional index finger pollicization, blood supply is maintained on the volar palmar arch. In case of index finger loss at the metacarpophalangeal joint, remaining length of the second metacarpal is often not used for pollicization because the arc of rotation is limited on digital arteries. In this report, we present a surgical technique for the transfer of the index metacarpal to the thumb on the dorsal vascular network. This method adds no further morbidity and can be used as an alternative method of thumb reconstruction in cases in which the thumb and index fingers are amputated.
