Conventional osteomyocutaneous flaps do not always meet the requirements of a composite defect. A prefabricated composite flap may then be indicated to custom create the flap as dictated dy the complex geometry of the defect. The usual method to prefabricate an osteocutaneous flap is to harvest a nonvascularized bone graft and place it into a vascular territory of a soft tissue, such as skin, muscle, or omentum, before its transfer. The basic problem with this method is that the bone graft repair is dependent on the vascular carrier; the bone needs to be revascularized and regenerate. The bone graft may not be adequately perfused at all, even long after the transfer of the prefabricated flap.
