Computer-assisted navigation and musculoskeletal sarcoma surgery.

BACKGROUND Despite advances in medical, surgical, and radiation oncology, deep-seated bone sarcomas that require large osseous resections continue to present resection and reconstructive challenges to musculoskeletal surgeons. METHODS We describe our experience with computer navigation techniques combined with complex pelvic resections and limb-preserving surgeries. RESULTS Computer-assisted navigation has shown promise in aiding in optimal preoperative planning and in providing more accurate and precise feedback during surgery. CONCLUSIONS Computer-assisted navigation offers precise instrumentation, technology-oriented imaging systems, and powerful information processing, all of which can assist in decision making, preoperative planning, and surgical accuracy.
