Abstract: Sensate cross-finger flaps and homodigital and heterodigital island flaps can usually be used for sensory reconstruction in the volar aspect of the digit. However, when the donor areas are damaged by concomitant injuries, these flaps are not available. The free dorsal digital flap, including both dorsal branches of the proper digital nerves, can be used as an alternative to resolve this problem. The flap was used in 16 patients with soft tissue defects on the volar aspect of the digits. For comparison, we collected a consecutive series of 31 patients with similar defects treated using a cross-finger flap including one branch. At final follow-up, the static 2PD of 2-branch flap is superior to 1-branch flap. The dorsal digital sensate free flap can be used as an alternative for the reconstruction of volar soft tissue defect of the digits. Sufficient sensory recovery can be achieved using this technique.
