Infected large defect of the long bone have had many obstacles in treatment. It is usually very difficult to obtain union and to correct coexisting infection, deformity, & leg length discrepancy. Allograft transplantation have been traditionally
used to
treat infected large defect of the long bone. And Ilizarov techique has recently gained popularity as a multifactorial approach to themanagement of infected large defect of the logn bone. We performed allograft transplantation in 5 cases and
Ilizarov
technique in 6 cases with infected large defect of the long bone at National Medical Center from 1987 through 1991.
@ES The results were as follows:
1. in the five cases of allograft transplantation. the average size ofthe bone defect was 9.6cm (range from 6cm to 3cm) and the average length of leg length discrepancy was 2.4cm (range from 0cm to 4cm).
2. In the six cases of Ilizarov technique, the average size of the bone defect was 2.5cm (range from 0.5cm to 4.5cm) and the average length of leg length discrepancy was 3.7cm(range from 0cm to 7cm).
3. In the cases of allograft transplantation, the bone union was achieved in two cases. Two cases have been followed up for 19 to 26 months each and they showed complete bone union in the proximal side of host-graft junction. but not complete
union
in
the distal side. In one
case, developed the osteolysis of the grafted bone due to the infection. After operation, the
average length of leg length discrepancy was 1.4cm(range from 0cm to 2cm0
4. In the cases of Ilzarov technique, bone union was achieved in three cases. One case have been followed up for 15 months and showed incomplete bone union, In two cases. additional operation was performed due to the nonunion and the fracture
between
the junction of the proximal bone fragment and the transportated bone fragment in each.
So we report our results ofdifferent two methods of treatment even if limited cases and
experiences.
