[Pedicled vascularized bone graft for vascular alternation in scaphoid cadaveric study].
BACKGROUND
Use of vascularized bone grafts makes possible to transfer useful vascular preserved bone.


METHODS
Experimental model.


OBJECTIVE
To create an experimental model to obtain vascularized bone graft. To describe anatomic characteristics of the graft.


METHODS
Dissections were performed in 10 experimental models, 6 cadavers were male, 4 female, 5 hands were right and 5 left.


RESULTS
Artery staining, was successful in 8 hands, and failed in 2. Length of the graft was appropiate in 10 dissections, and the quality of the pedicle, was adequate in 8 hands, 2 failures were due to destruction of the pedicle.


CONCLUSIONS
Vascularized bone grafts have multiple clinical applications, for example: carpal Nonunion, failed arthrodesis, osteonecrosis (Kienbock's), and bone deficiencies.


CONCLUSIONS
This experimental model to obtain vascularized bone grafts is feasible and reproducible, and avoids the risk for patients during the surgeon's learning curve. One of the advantages in a cadaver dissection is absence of bleeding. Caveats for this technique are its complexity in identifying arteries and the technical difficulties such as rigid tissues and dry skin.
