| FIG. 2-05. The sensory island flap has been used to resurface the entire volar tactile surface of the thumb, anastomosing the digital nerve from the lateral side of the toe to the digital nerves of the thumb and reestablishing normal cortical orientation to the sensory pinch area of the thumb.
An avulsive injury of the entire distal phalanx of the thumb was resurfaced circumferentially with a groin flap.
FIG. 2-08. The groin flap is floppy, insensate, and unaesthetic.
In this case, there was partial amputation of the pulp substance of the distal radial aspect of the thumb, with marked deformity of the nail and loss of most of the nailbed.
FIG. 2-11. In this instance, the neurovascular island flap not only carries the normal pulp substance of the great toe but the entire nail plate of the great toe, plus a shaving of bone from the distal phalanx, similar to a "wraparound. "
