Free Flap Vs. Pedicled Flap
Pedicled flaps involve the same movement of muscle or other tissues, but differ from free flaps in that the pedicle (blood supply) to the flap are not cut. Instead the pedicle is dissected so that the flap can be moved directly or through a tunnel created under the skin to the defect area. Pedicled flaps are usually quicker to perform and are much more robust, but depending on the defect and anatomy, are not always possible.
Free flaps can be very complex and lengthy surgeries. Length commonly ranges from 6 to 12 hours but can take longer based on the complexity (microscopes are used).
Finger and hand reattachments use the same microvascular techniques.
The suture used to reattach blood vessels is typically made of nylon.
Many successful free flap surgeries are performed every day.

Famous quotes containing the words free and/or flap:
“Next to our free political institutions, our free public-school system ranks as the greatest achievement of democratic life in America ...”
—Agnes E. Meyer (1887–1970)
“Let Sporus tremble—‘What? That thing of silk,
Sporus, that mere white curd of ass’s milk?
Satire or sense, alas, can Sporus feel,
Who breaks a butterfly upon a wheel?’
Yet let me flap this bug with gilded wings,
This painted child of dirt, that stinks and stings;
Whose buzz the witty and the fair annoys,
Yet wit ne’er tastes, and beauty ne’er enjoys:”
—Alexander Pope (1688–1744)
