Amputation or degloving injuries of the thumb or index finger are highly disabling. We describe the use of twin dorsal middle finger flaps harvested from the dorsal aspects of the middle and ring fingers, and based on one palmar proper digital artery, its venae comitantes, and the dorsal branches of the palmar digital nerves of the middle and ring fingers, respectively. These flaps offer advantages when large soft tissue defects of the thumb or index finger are present. In this study, twin dorsal middle finger flaps were used in nine patients (six thumbs, three index fingers). All flaps completely survived. At the mean follow-up of 20 months, the appearance of the reconstructed thumbs or index fingers was acceptable, the length was maintained, and the mean static 2-point discrimination values were 10 mm in the palmar flap and 13 mm in the dorsal flap of the reconstructed digit. All patients were satisfied with the appearance and mobility of the donor fingers. All but one donor finger showed normal finger pulp sensibility, with a static 2-point discrimination between 3 and 6 mm.
