A cortico-cancellous flap from the anterolateral aspect of the upper t
hird of the tibia was presented. Sixty lower limbs of ''fresh'' cadave
rs were dissected. The vascular bundle includes the anterior tibial ar
tery and its recurrent collateral branches and recurrent and muscllo p
eriostal arteries. The flap is harvested with the interosseous membran
e and can be used either free or pedicled. We used this flap for two p
atients suffering from pseudarthrosis. Long range clinical and radiolo
gical results are good.
