The posterior interosseous flap: a review of 81 clinical cases and 100 anatomical dissections - assessment of its indications in reconstruction of hand defects

Based on our experience of 100 cadaveric dissections and a series of 81 cli nical cases, we have assessed the indications for the posterior interosseou s flap in reconstruction of the hand. Large fasciocutaneous island flaps ca n be harvested, even when the radial or ulnar pedicles are damaged, sacrifi cing only vessels of secondary importance to the perfusion of the hand. Com pound flaps can be dissected based on muscular, musculoperiosteal and fasci operiosteal branches. The primary indications for using this flap are dorsa l hand defects up to the metacarpal joints, reconstruction of the first web space up to the interphalangeal joint of the thumb and extensive lesions o n the ulnar border of the hand.
