Limb salvage is preferred over amputation when margins can be obtained and function preserved. Endoprostheses replace resected bone segment, especially around knee and proximal humerus. Types: modular, custom‑made, expandable (pediatric). Complications: infection, aseptic loosening, mechanical failure, soft tissue problems. Survival: 70–80% implant survival at 10 years; improves quality of life over amputation.
