Posterior interosseous artery flap: our experience and review of modifications done.

This is a report on the 14 PIA flaps done in our centre for traumatic hand defects over both volar and dorsal aspects, as well as thumb reconstruction over a six-year period from 2000 to 2007. We were able to achieve reach to the DIPJ with the use of fascia extension and better flap survival with more perforators captured in the flap.
