Limb Salvage Surgery in Bone Tumors
Oncologic principles: accurate diagnosis, staging (MRI, PET/CT), biopsy planning, and **wide margins**. Indications: resectable tumors with adequate soft-tissue coverage and neurovascular preservation; good chemo response when applicable. Reconstruction options: endoprosthesis (modular/mega), biological (intercalary grafts, vascularized fibula, allograft), arthrodesis. Complications: infection, flap failure, nonunion, prosthetic loosening, local recurrence. Multidisciplinary planning is essentia...
