[Clinical application of expanded forearm reverse dorsal interosseous artery island flap].

The island flap based distally on the posterior interosseous artery has been proven to be available for the correction of severe cicatricial contracture deformity of the ipsilateral hand. However, the main disadvantages of this flap are the second donor area deformity and muscle or tendon adhesions after skin grafting. Both these complications may be ameliorated by means of tissue expansion to obtain a secure blood supply to the flap. The surgical procedure has been performed in 7 patients with satisfactory result since August 1989.
