Recent advances in microsurgery have made it possible to provide a continued circulation of blood to the grafted bone so as to ensure viability. With the nutrient blood supply preserved, healing of the graft to the recipient bone is facilitated without the usual replacement of the graft by creeping substitution. We reviewed 34 cases of vascularized osteocutaneous fibular transfers to the infected tibial defect complicated with skin defect, which were performed from May, 1982 to January, 1992, and the following results were obtained: 1. Despite of uncontrolled bone infection with skin defect, the vascularized osteocutaneous fibular flap transfer could be performed. 2. In the vascularized osteocutaneous fibula transfer, the patency of anastomoses could be indirectly monitored by observing the color of the skin flap. 3. The vascularized fibula had been hypertrophied with bony union during the follow-up period of 13 months to 6 years and 4 months(average, 30 months) and there was no resorption of the grafted fibula. 4. There was no fracture of the grafted fibula in parti resection of involved tibia. 5. The hypertrophic potentiality of grafted fibula could be inhibited by the infection status as operation site.

Purpose : We have evaluated the morbidity of donor site after transfer of free fibular osseous and osteocutaneous flap to defect site of bone and soft tissue due to chronic osteomyelitis of long tubular bone, open fracture with bony defect, bone or soft tissue tumor and congenital anomaly. Materials and methods : The 54 cases of 79 cases to be carried out from May, 1982 to May, 2001 which could be followed up were reviewed. There were forty nine in male and five in female. The mean age was 35(4 to 66)years old and mean follow up period is 21.3 month(12 to 72). We have retrospectively analyzed the various postoperative complications such as compartment syndrome, donor site infection, skin defect, hypesthesia, hammer toes, ankle instability and activity of daily living by help of questionnaire, telephone, physical examination, follow up x-ray study and chart. Results : In the total 54 cases the medication period for pain control after operation were classified into three groups under 2 weeks(49 cases), from 2 weeks to 6 weeks(3 cases) and over 6 weeks(2 cases). The postoperative morbidity were occurred in total 12 cases(compartment syndrome: 0, infection : 2, skin defect: 1, hypesthesia: 5, hammer toe: 2 ankle pain: 2 discomfort in activity of daily living: 0), and also the morbidity rates of donor site were 23.5% in osseous flap and 21.6% in osteocutaneous flap were occurred. There was no statistical significonce in morbidity between osseous and osteocutaneous free fibular flap transfer(P>0.05). Discussion : In general the morbidity of free fibular flap transfer was relatively high but it did not have any effect on daily activity of living. We think that the meticulous operation technique, detailed wound care and early range of motion exercise will reduce the morbidity of donor site of flap.

Purpose : To analyze the clinical results of free vascularized osteocutaneous fibula graft to tibial defect combined with soft tissue defect and infection. Materials and Methods : In the retrospective study of 51 consecutive cases of vascularized osteocutaneous fibular graft, the length of the grafted fibula, size of the skin flap, anastomosed vessels, ischemic time of the flap, time for union, hypertrophy of fibula and the complications were evaluated. Results : Initial bony union of the grafted fibula was obtained at 3.74 months after operation, except 4 cases of nonunion and delayed union. The weight bearing without external supports was possible at 18 months after operation in average. The fracture of grafted fibula was most common complication(16 cases). Conclusion : The vascularized osteocutaneous fibula graft provided satisfactory bony union and functional results in the cases not responsible for conventional treatment methods.

February 1995 to September 1999, authors have experienced seven cases of infected nonunion of tibial fractures with associated soft tissue injury and skin defect, and have accomplished union in all cases by free vascularized fibular graft. All grafts healed with no radiographic evidence of bone necrosis or resorption and have been able to treat large bony defect and skin defect simultaneously. In this study, five cases of vascularized free fibular osteocutaneous flap transfer and two cases of free fibular graft are reported. All of seven cases were infected nonunion of tibia. The results were obtained as follows 1) The mean duration of the radiologic bone union was average 5.3months. 2) Grafted fibular has been hypertrophied, average 10.6 months. 3) In five cases of preservation of posterior cortex of tibia, bony union and hypertrophy of grafted bone were earlier than that two cases of complete segmental resection of tibia. 4) In two cases which only free vascularized fibular graft were performed because achievement of cutaneous flap was failed, authors found that soft tissue defect was filled with granulation tissue and split-thickness skin graft was possible over the granulation tissue after 3 weeks postoperatively.

We have evaluated the clinical results following the 46 cases of free vascularized osteocutaneous fibular flap transfer to the tibial defect combined with skin and soft tissue defect, which were performed from May 1982 to January 1997. Regarding to the operation, flap size, length of the grafted fibula, anastomosed vessels, ischemic time of the flap and total operation time were measured. After the operation, time to union of grafted fibula and the amount of hypertrophy of grafted fibula were periodically measured through the serial X-ray follow-up and also the complications and results of treatment were evaluated. In the 46 consecutive procedures of free vascularized osteocutaneous fibular flap transfer, initial bony union were obtained in the 43 grafted fibulas at average 3.75 months after the operation. There were 2 cases in delayed unions and 1 in nonunion. 44 cutaneous flaps among the 46 cases were survived but 2 cases were necrotized due to deep infection and venous insufficiency. One necrotized flap was treated with latissimus dorsi free flap transfer and the other was treated with soleus muscle rotational flap. Grafted fibulas have been hypertrophied during the follow-up periods. The fracture of grafted fibula(15 cases) was the most common complication and occurred at average 9.7 months after the operation. The fractured fibulas were treated with the cast immobilization or internal fixation with conventional cancellous bone graft. In the cases of tibia and fibula fracture at recipient site, the initial rigid fixation for the fibula fracture at recipient site could prevent the fracture of grafted fibula to the tibia.
