Ilizarov Technique — Principles

Tension‑stress effect: gradual distraction (≈1 mm/day in 4 steps) after corticotomy induces regenerate bone and soft‑tissue adaptation. Circular fixator with tensioned wires permits multiplanar stability and early weight bearing. Phases: latency (5–7 d), distraction, consolidation; rate/rhythm critical to regenerate quality. Indications: nonunion (infected), bone loss (transport), deformity correction, limb lengthening. Complications: pin site infection, joint contractures, poor regenerate, psychological burden.
