Nonunion & Bone Transport — Ilizarov
Ilizarov fixator allows bone transport for segmental loss. Principle: distraction osteogenesis by gradual tension on callus. Indications: infected nonunion, bone loss, deformity correction. Protocol: latency 5–7 days, distraction 1 mm/day (0.25×4). Complications: pin site infection, joint stiffness, regenerate problems.
