[Use of Ilizarov fixator in the treatment of post-osteomyelitis pseudoarthroses in children]

The aim of this study was to emphasize the importance of the distraction osteogenesis technique in the treatment of post-osteomyelitis nonunion. We report 12 cases.Mean patient age was 9.5 years. There were 7 cases of nonunion of the femur and 5 involving the tibia. Nonunion was associated with 5.9 cm shortening in 10 cases, 8.4 cm circumferential bone defect in 1 case, shortening and bone defects in 6 cases, and shortening and joint deformities in 2 cases.Consolidation was obtained in 11 cases with an average delay of 11.6 months. Infection was eradicated in 75 per cent of the cases. Average residual shortening was 0.4 cm. Joint deformities and axial deviations were corrected at the same time in all cases.The advantages of the Ilizarov technique are well known for the treatment of such deformities and musculoskeletal system disorders subsequent to osteomyelitis: nonunion, infection, shortening, joint deformities and malunion.
