Cross finger flap. A new technique.

Avulsion injuries of the thumb resulting in volar defects and loss of neurovascular bundles are presented. Treatment should aim at restoration of the skin and pulp with as near normal sensation as possible. A new technique is described using a cross-finger flap or flaps with transfer of the superficial terminal branch of the radial nerve. It is claimed that this gives near normal restoration of sensation to the tactile surface of the thumb. The fingers may be treated in the same way for similar injuries.
