Abstract
Abstract Posterior interosseous flap is an island fascio-cutaneous flap located on the dorsal forearm surface. Based on a. interossea posterior it can be lifted by a distal pedicle thanks to the anastomosis with a. interossea anterior in the wrist area. In the present paper 12 clinical cases are reported. This flap has been used to cover various interesting hand defects such as ulnar and dorsal as well as lesions in the area of the first commissural. The role of the application of this particular flap in hand reconstruction has been outlined.
