Abstract
Latin for “sacred bone” and so named for its recurrent role in ancient Greek and Egyptian mythology [1], the os sacrum remains the subject of much discourse and scholarship in modern-day musculoskeletal oncology. The treatment of sacral tumors demands attention to the complex interplay of anatomic, biomechanical, and oncologic considerations. However, with meticulous preoperative planning and input from a specialized multidisciplinary team, good functional and oncologic results can be obtained in the surgical management of these tumors.
