[Use of posterior interosseus artery flap in the repair of forearm and hand].

The posterior interosseous vessels give a significant contribution to the fascial plexus which supplies the skin of the forearm. This vascular arrangement forms the basis for an island fasciocutaneous flap which can be based either proximally or distally. Its principal advantage is that it is a thin flap with excellent circulation and that the donor area can be closed primarily. The design and usage of an island fasciocutaneous flap with possibility of expansion is also described.
