A VERSATILE ONE-STAGE NEUROVASCULAR FLAP FOR FINGERTIP RECONSTRUCTION - THE DORSAL MIDDLE PHALANGEAL FINGER FLAP

The dorsal middle phalangeal finger flap is an extremely reliable flap that is indicated for fingertip injuries which require sensory reconstruction. This flap originates from the dorsum of the middle phalanx of the finger and is elevated with a vascular pedicle of the digital artery and the dorsal branch of the digital nerve. After transfer of the flap to the injured site, epineural neurorrhaphy is done between the digital nerve and the dorsal sensory branch of the flap. This flap can be thought of as an island flap of the innervated cross-finger flap that provides excellent sensory recovery and aesthetic improvement. We used this flap in a series of eight consecutive patients and were able to follow up seven patients for longer than 6 months (mean follow-up time 10.7 months). All patients achieved measurable two-point discrimination, with an average of 4.9 mm in the moving two-point discrimination. In this study, we report our consecutive series of the dorsal middle phalangeal finger flap and its versatile utility.
