Malunion Correction — Principles

Malunion = fracture healed in unacceptable alignment causing functional, cosmetic, or biomechanical issues. Decision to correct depends on symptoms, joint at risk, magnitude/plane of deformity, and patient goals. Thorough planning with long‑leg alignment views, scanogram, and CT rotational profile is essential. Osteotomy at CORA restores axis with least translation; fixation by plate, nail, or circular frame. Common techniques: closing wedge, opening wedge (needs graft), dome, step‑cut, and gradual correction (Ilizarov/Hexapod).
