Dr. Douglas Letson and Dr. David Cheong are working to develop a navigational system for musculoskeletal tumor surgery. Currently, the surgeons at Moffitt have performed more than 20 complex orthopedic oncology cases (such as hemipelvectomies, total femur replacements, and proximal and distal femur replacements) using navigation for limb salvage surgery and segmental prosthetic reconstruction. With the development of these new techniques for navigation, surgical resections (tumor removals) are more precise and accurate by using fused MRI and CT scans. A clearer, multidimensional image of the limb allows for more accurate surgical resections and easier reconstructions.
Moffitt Cancer Center has installed a Stryker Navigational Room specifically designed to improve limb salvage surgery and pelvic resections using the new navigation oncology software system. In this state-of-the-art navigation room, surgeons perform complex tumor surgery with less complications and more accuracy. Accuracy and improved visualization are fundamental variables in procedures such as pelvic resections (tumor removals) where exposure is difficult and vital anatomic structures are in close relationship with the tumor mass. In addition to enhancing the exposure of difficult anatomic regions, the use of navigation permits exact evaluation of limb length and rotation of components for procedures in the appendicular skeleton. With the use of computer-navigated systems, we are improving limb salvage surgery and improving the accuracy of the resections and reconstructions. Patients have a higher probability of clear, surgically resected margins with less risk of complications or damage to vital structures and pinpoint accuracy in reconstruction of the appendicular and axial skeleton.
