Introduction:
The "Foucher" flap is a pedicled neurovascular island flap of the first dorsal metacarpal artery.
Methods:
From 1992 to 2000, thirty-three neurocutaneous island flaps from the dorsal aspect of the index finger (FDMCA flap) were performed for defect coverage and reconstruction of sensibility in the thumb.
Results:
Static 2-PD over the flap area averaged 10.8 mm (range 4-15), compared to 8.2 mm (4-15) over the dorsal aspect of the contralateral index finger. Response to the SW monofilaments showed no difference to normal skin or only diminished light touch in 76% (19/25) patients. Seventy-six percent (19/25) were able to return to their previous jobs or resume previous activities.
Conclusion:
Based on negligible donor site morbidity of the flap and the good sensate quality and aesthetic appearance, the Foucher flap has become our first choice in defect coverage and restoration of sensibility of the thumb.
