摘要

Musculoskeletal tumor surgery is characterized by its interdisciplinary nature, complexity, and individualized approach. The primary objective is an R0 resection—a complete removal of the tumor with clear margins—in order to reduce the risk of recurrence and improve long-term survival. A careful, individualized balance must be struck between the extent of resection required from an oncological perspective and the amount of tissue or function to be preserved from a functional perspective. Classic resection techniques, such as those described by Enneking and Durham, can be customized through the use of modern assistance systems. These systems are collectively referred to as “computer-assisted surgery” (CAS) systems and have undergone a remarkable evolution over the past 20 to 25 years. They encompass image-based navigation, robot-assisted navigation, augmented reality navigation, and patient-specific instruments and implants (PSI). First studies have demonstrated the superiority of CAS systems over manual resection techniques with regard to achieving R0 resections and improving long-term survival outcomes. This article aims to introduce CAS systems and provide an outlook on potential avenues for future development.
