The surgical approach to benign, metastatic, and some low-grade malignant tumors is often difficult due to their typically precarious locations. This article presents a series of cases where intraoperative stealth navigation was used to treat periarticular tumors. The use of paired point imaging with image fusion has made approaching tumors through an accurate and minimally invasive technique a viable option for the treatment of a subset of musculoskeletal tumors. Conventional resection of periarticular and pelvic tumors of bone usually requires an extensive surgical approach to adequately visualize the tumor and protect the nearby neurovascular structures. When tumors in periarticular locations are encountered, dislocation of the affected joint may be necessary, putting periarticular and subchondral bone at risk for osseous necrosis and articular surfaces at risk of mechanical insult at the time of dislocation. While arthroscopic techniques may enable a minimally invasive mode of surgical approach in certain anatomic locations, this is not always feasible and can add additional operative time and morbidity to the patient. This article describes 5 cases where locally aggressive tumors in challenging periarticular anatomic locations were treated in a minimally invasive manner with the assistance of image fusion and paired-point registration.
