Fibular-Lengthening Osteotomy in Patient with Progressive Valgus Deformity After an Ankle Fracture.

BACKGROUND The fibular fracture requires an anatomical reduction. When a malunion occurs, it can lead to a valgus deformity with an opening of the ankle mortise. CASE REPORT This case deals with a 23-year-old patient with pain and limited movement in the right ankle, caused by a fracture healed in an incorrect position, with shortening of the fibula and progressive displacement of the valgus, after surgery 12 months earlier for an ankle fracture.
