[Comparison of long bone repair in tibia by vascularized fibular grafting of different sides].
OBJECTIVE
To evaluate the clinical effect of repair of massive bone defect in tibia by vascularized fibula grafting of either sides.


METHODS
Twenty-four cases of massive bone defect in tibia, among which 14 case were repaired by vascularized fibula grafting of the other side and another 10 cases were repaired by those of the same side, from 1987 to 1997 were followed up for 3 to 13 years; the functions of the operated limbs were evaluated according to Enneking Score System, and the outcome of the fibula grafts were assessed by radiographic examination with reference to the standard established by International Symposium on Limb Salvage.


RESULTS
The average recover rate of the operated limbs in those repaired by the other side grafting was 80.7%, and the average healing period of the fibula graft was 14 weeks with fracture of the graft in one case which made the operated lower limb shorten for about 2.5 cm; the fibula grafts were observed thickened in 43 weeks, on average, and the patients could walk independently without a crutch. While in those repaired by the same side grafting, the average recover rate of the operated limbs was 68.3%, the average healing period of the fibula graft was 17 weeks with fracture of the graft in 3 cases, in 2 of which the lower limbs were shortened for 2 cm and 4 cm respectively, and in the third one infection occurred and amputation was performed finally; the fibula grafts were observed thickened in 49 weeks, on average, which made it available for the patients to walk without a crutch. All of the data showed that there was a significant difference statistically between the differently treated cases.


CONCLUSIONS
It's a good choice to repair massive bone defect in tibia by vascularized fibula grafting, and the vascularized fibula graft from the other side could promote the bone healing and accelerate the recover of the function of the operated lower limb.
