The authors present the anatomy and clinical applications of a new donor site for free or pedicled transfers. It is localised on the posterior aspect of the forearm, over the distal radius, and based on a posterior branch of the anterior interosseous artery. It can be used as a free skin flap, osteoperiosteal or osteocutaneous transfer. Reinnervation is possible. Indications in hand surgery are numerous. Five consecutive cases have been operated upon successfully.
