The bilobed flap: a new application in the reconstruction of congenital thumb deviation.

Congenital radial angulation deformity of the thumb in Rubinstein-Taybi syndrome is generally corrected by a wedge osteotomy of the delta phalanx and a redistribution of the overlying skin using a Z-plasty or, rarely, skin grafting. We describe a new application of the bilobed flap in the reconstruction of the thumb and discuss its advantages over traditional methods in providing tension-free skin cover, excellent access to the delta phalanx and aesthetically acceptable scars.
