Correction of Equinus Deformity by Ilizarov Frame Using the Matsushita Method and Achilles Tendon Lengthening

Case: The patient was an 18-year-old man who had sustained diaphyseal fractures of the left femur and tibia in a traffic accident and underwent surgery at another hospital. A severe left foot equinovarus deformity developed in the early after surgery. The patient's left foot deformity was addressed using unconstrained gradual external fixator correction (the Matsushita method) in combination with soft-tissue contracture through Achilles tendon lengthening and was maintained after removing the external fixation. Conclusion: The Matsushita method can be effective in the correction of post-traumatic equinovarus foot deformities.
