The Malawer method for musculoskeletal cancer surgery revolutionized limb‑sparing procedures by combining wide‑margin oncologic resection with functional reconstruction. It relies on precise imaging, intra‑operative navigation, and a spectrum of reconstruction techniques—from modular endoprostheses to biologic grafts—tailored to the tumor’s location and patient’s needs. Outcomes demonstrate comparable survival to amputation while preserving quality of life, though vigilance for complications such as infection and prosthetic failure remains essential.
