Indicated for skeletally immature patients undergoing limb-salvage near a growth plate (e.g., distal femur/proximal tibia). Designs: minimally invasive magnetically driven expanders vs older surgical-lengthening types. Aims to maintain limb length equality during growth while preserving function and oncologic safety. Complications: infection, mechanical failure, soft-tissue problems, stiffness; multiple lengthenings required. Requires multidisciplinary follow-up through growth until maturity.
