Longitudinal Splitting Free Vascularized Fibular Transplantation

종축 절골편을 이용한 생비골 부분이식술

Free vascularized fibular transplantation is one of the most useful living bone reconstructive procedure in microsurgical field. Concerning about donor site morbidity, the donor has minor problems of ankle stability and muscle power weakness and transient peroneal nerve symptoms. That problems can be minimized with longitudinal splitted osteotomy on the donor fibula if the bone defect in recipient site is not so large. Half splitted fibula with peroneal arterial pedicle which contains nutrient artery and periosteal vessels, grafted bone can survive with those vascular supplies. Authors underwent five cases of half splitted free vascularized fibular transplantation from 1985. There were no evidence of devascularization in all cases, we can minimized donor morbidity with leaving half fibula intact on donor site. The problem of that technique is technically demanding in longitudinal splitting of bone without damage to peroneal nutrient vessels and periosteal soft tissues which attached to the bone. Authors can propose longitudinal half fibular transplantation is one of modification in free vascularized bone transplantation that minimize donor defect.
