ABSTRACT

Introduction: Use of vascularized bone grafts makes possible to transfer useful vascular preserved bone. Design: Experimental model. Objectives: To create an experimental model to obtain vascularized bone graft. To describe anatomic characteristics of the graft. Intervention: Dissections were performed in 10 experimental models, 6 cadavers were male, 4 female, 5 hands were right and 5 left. Result: 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. Discussion: Vascularized bone grafts have multiple clinical applications, for example: carpal Non-union, failed arthrodesis, osteonecrosis (Kienbock’s), and bone deficiencies. Conclusion: 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.


Key words: hand, graft, experimental model, osteonecrosis, carpal bones.
