Vascularized bone grafts for the management of skeletal defects in orthopaedic trauma and reconstructive surgery

Bone loss from trauma, neoplasia, reconstructive surgery and congenital defects remains a major health problem. The long-term clinical goal is to reconstruct bony tissue in an anatomically functional three-dimensional morphology. In the extremities, bone grafts are used for the treatment of non-unions and necrotic lesions, for skeletal structural support and for the reconstruction of defects resulting from trauma, tumor excision, osteomyelitis, congenital pseudarthrosis, or radiation necrosis. In all cases their use is successful provided that the host bed has adequate vascularization. In cases of decreased blood supply, a vascularized bone graft should be applied. The intrinsic blood supply of the vascularized bone grafts leads to higher success rates and to acceleration of the repair process in the reconstruction of defects and necrotic lesions of the skeleton.
