Introduction: Residual orthopedic deformities after meningococcal infection in infancy, including severe angular deformities and leg length discrepancy (LLD), affect patient quality of life.

Case presentation: We report the case of an adolescent female with severe varus deformity and LLD of her right femur. We applied a preconstructed Ilizarov frame and initially corrected the varus deviation with different rates of rod elongation and appropriate hinges. We then completed the correction by performing usual lengthening procedures to address the LLD.

Conclusion: Treatment with distraction osteogenesis with the Ilizarov frame enabled the restoration of the anatomical axis and severe LLD of the legs.
