Abstract
The reverse digital arterial island flap is usually used for finger pulp reconstruction. Endo et al first described the variant procedure, innervated island flap. (1992). The superficial sensory branch of the dorsal digital nerve is sacrificed including it within the flap, then it is reanastomosed to the digital nerve stump on the affected side in order to improve sensory recovery of the pulp, with excellent results (one-sided neurography).We summarized nine finger pulp reconstruction patients in our section and the follow-up time was at least six months after the procedure. All the patients' flaps survived completely, without other surgical complications. We analyzed the sensory recovery of post-reconstructive pulps by using a moving two-point discrimination test (M-2PD test) and sensory recovery score (SRS). In our limited experience, the flap has many advantages including: bulky pulp volume maintenance, shorter hospitalization, single stage operation, good sensory recovery and less donor site morbidity. The innervated flap had better sensory recovery than the non-innervated flap.
