The chosen approach should align with the future resection line to prevent tumor seeding and preserve limb-salvage options.Core needle biopsy is preferred for most lesions,…
Prepared by Dr. Ali Erkan YENIGUL Tumour resection aims to achieve oncologic control while preserving function; margin status is critical for local recurrence risk. Historical Background Basic Principles Enneking’s Margin Classification Intralesional Curettage / piecemeal debulking / Macroscopic disease remains Marginal Shelling out via pseudocapsule- reactive zone / May leave satellite or skip lesions Wide En bloc with…

Enneking Staging – Bone Sarcomas…
prepared by Dr. Alper DUNKI Plain radiography remains the first-line and often diagnostic in most bone tumors, while CT provides detailed cortical and 3D anatomical evaluation. MRI offers superior soft-tissue and marrow contrast, essential for assessing intramedullary extension and surgical margins. PET/CT assist in detecting metastases and evaluating treatment response. 1. Introduction 2. Plain Radiography…
