Computer-assisted navigation in bone tumor surgery: seamless workflow model and evolution of technique.

ABSTRACT:

Background

Computer-assisted navigation was recently introduced to aid the resection of musculoskeletal tumors. However, it has not always been possible to directly navigate the osteotomy with real-time manipulation of available surgical tools. Registration techniques vary, although most existing systems use some form of surface matching.

Questions/purposes

We developed and evaluated a workflow model of computer-assisted bone tumor surgery and evaluated (1) the applicability of currently available software to different bones; (2) the accuracy of the navigated excision; and (3) the accuracy of a new registration technique of fluoro-CT matching.

Methods

Our workflow involved detailed preoperative planning with CT-MRI image fusion, three-dimensional mapping of the tumor,
