In the surgical management of primary bone cancer, tumor surgeons formulate a three-dimensional (3D) surgical plan after analyzing two-dimensional (2D) medical images. It is prone to surgical inaccuracy as it is challenging to translate the plan to the operating room in complex cases with distorted anatomies, like in pelvic or sacral tumors or technically demanding operations, like geometric or joint preserving resections. The surgical inaccuracy with a positive surgical margin may result in an increased risk of local tumor recurrence and patient mortality. Incorrect planes of bone resections may compromise the matching to the bone reconstruction, leading to inferior limb functions.
