Navigation-Assisted Orthopedic Surgery in Bone Tumor / 대한정형외과학회잡지

ABSTRACT

The usefulness and accuracy of computer-assisted surgery have been evaluated clinically in many orthopedic fields, including joint replacement arthroplasty, pedicle screw placement, and cruciate ligament reconstruction of the knee joint. Since several preliminary reports on application of navigation to bone tumor resection and reconstruction surgery have recently been issued, navigation-assisted surgery for bone tumors has received significant attention with regard to its usefulness. In particular, navigation can be helpful during surgery for musculoskeletal tumors, because it can maximize the accuracy of resection and minimize the unnecessary sacrifice of normal tissue by providing precise intraoperative three-dimensional radiological information. In addition, it is helpful in prosthetic reconstruction, because preoperative virtual simulation makes it possible to estimate size and location of bone defect to be left after tumor resection. Surgeons should recognize that use of navigation systems in bone tumor surgery has some hidden pitfalls. Here, based on our clinical results, we describe the surgical techniques that we have used and include some cautionary notes.
