Endosteum and bone marrow thermal necrosis caused by reaming during tibial intramedullary nail insertion, and unskilled operation of soft tissue penestration by reamer resulted in chronic osteomyelitis and soft tissue defect. So, several times of free flaps were done but the result was unsuccessful. At last, the authors performed radical necrotic bone resection and internal bone transport using Ilizarov external fixator. The authors report case with literature review.
PURPOSE To evaluate the results of bone transport using external fixator over an intramedullary nail for defects of long bone. MATERIALS AND METHODS We treated 14 cases of bone defect after chronic osteomyelitis or trauma of tibia (12 cases) and femur (2 cases) using this method. The mean age of index procedure was 46.9 years, and all of them had follow-up study for a mean of 3 years. After the corticotomy and insertion of intramedullary nail, bone transport was done by external fixators. Then, the segment was moved and bone graft was done at docking site. RESULTS The mean transported amount was 5.8 cm, and the external fixator was removed after 141 days. The mean external fixation index was 25.6 days/cm. Primary union of distraction and docking site was achieved in all, but one had failure in union of docking site. According to the Mekhail's functional criteria, there were 5 excellent, 6 good, and 3 fair results. Among 15 complications, there were 2 major complications with residual sequelae, and they were 1 recurred osteomyelitis and 1 flexion contracture of knee. CONCLUSION Bone transport using external fixator over an intramedullary nail, can successfully solve defects of long bone. Since this method can remove external fixators earlier than the conventional method, it has fewer complications and makes patients to return to daily life earlier.

PURPOSE To retrospectively review the results of internal bone transport in the management of tibial bone defect using ilizarov fixator. MATERIALS AND METHODS We treated 39 cases of tibial bone defect (16 of traumatic bone loss, 23 after treatment of osteomyelitis). The mean age of index procedure was 33.8 years (range, 13~66 years), and all of them had follow-up study for a mean of 3.5 years (range, 1.6~8 years). The mean transported amount was 6.3 cm (range, 2.7~20 cm), and the external fixator was removed after 345 days (range, 120~700 days). The mean external fixation index was 60.3 days/cm (range, 13.1~121.3 days/cm). RESULTS Primary union of distraction and docking site was achieved in all, but two patients had failure in union of docking site. Functional results showed 6 excellent, 19 good, 10 fair, and 4 fair. The patients under age 20 showed better functional outcomes than the others. Among 73 complications (incidence, 1.87 cases/ patient), 27 of major complications with residual sequelae occurred in 20 patients. The residual sequelae were more common in the patients who had the concomitant injuries in the same leg. CONCLUSION Internal bone transport can solve the large amount of tibial bone defect. However, the complications are not uncommon, which might be related to the concomitant injures in the same leg.

Infected nonunion of long bone frequently accompanies with bone loss, because of the outcome of initial trauma or iatrogenic result from sequestra resection. In this study, infected and ununited long bone fracture was treated with internal bone transport technique which was first discribed by G.A. Ilizarov. There were eleven tibial and two femural nonunion. The mean number of admission was 2.8 times; mean number of operation was 8 times; mean duration of average healing index was 1.95 month/cm. All infections were cured and all nonunions were united. Functional result was excellent in 5 cases (of 13 cases), good in 5, fair in 2, and 1 had poor result. Many complication had been observed. All had infection of pin site and pain at least one time, 5 had stiff knee, 9 had stiff ankle, early consolidation(1), delay consolidation(3), tibiofibular synostosis(5), nerve injury(1), refracture after union(1), angular deformity over 5 degree(7), rotational deformity over 10 degree(2).
We experienced the local bone transportation in 3 cases. with a dynamic axial fixator, which had been effected the large bone defects because of the loss of the bony segment or infected non-union. The 2 patients showed the large femoral bone defect after motorcycle accident and the other patient. The tibial infected nonunion with large bone defect. The two femoral bone defects were treated by callotasis, and the tibial bone defect by chondrodiatasis.
The size of bony defects were 12.Ocm and 6.5cm and the amount of bony transportation were 10.Ocm, 9.4cm and 5.9cm in orthoroentgenogram.
These local bone transportations induced excellent osteogenesls and it filled up the defects We suggest that local bone transportation might be one of the best ways for the treatment of the large bone defects.
