Navigation Systems for Knee and Spine Surgery

New surgical navigation systems for knee and spine surgery are designed to improve implant placement accuracy and outcome and to reduce recuperation time for patients following an orthopedic surgical procedure.

The Navitrack TotalKnee computer-assisted orthopedic surgery (CAOS) software provides surgeons with a user-friendly application that guides them through total knee reconstruction surgery with a validation feature that optimizes accuracy and patient satisfaction. It provides easily identifiable alignment information, specific views of the knee, and animations showing key tasks to be performed when reconstructing the knee joint. A visual representation of the femoral and tibial axes through real-time digital imaging are also offered.

"In routine knee replacement surgery, as many as 25% of the cases can result in alignment errors of more than three degrees. In a recent study of 74 patients, the Navitrack TotalKnee applications reduced this amount of inaccurate alignments to under 5%,” said Dr. Louis-Philippe Amiot, chairman and CEO, Orthosoft, Inc. (Montreal, Canada).

A companion system, Navitrack PSP 4.0 3D image-guided software, is designed to reduce the complication rates of conventional spinal operations. According to Orthosoft, it is the only application available today to display multiple tracked vertebrae simultaneously for an intraoperative visual assessment of the spinal curve correction. Navitrack PSP supports implantation of the pedicle screw fixation systems to correct and stabilize congenital and acquired deformities, as well as truama and degenerative diseases of the spine.
