Neurovascular island flap by the disconnecting-reconnecting technique.

The authors report nine cases of hetero-digital neurovascular island flaps raised by the "disconnecting-reconnecting" technique for defects of the tactile pad of the thumb. At an average follow-up of 25 months, all cases had good restoration of sensibility without any "double sensibility" phenomenon and patients regained good dexterity. No tender neuromata developed and donor site complications were not troublesome.
