NEW TECHNOLOGY ENHANCES COMPUTER-GUIDED JOINT REPLACEMENT SURGERY; FIVE OPERATIONS ALREADY PERFORMED AT HADASSAH
(New York, NY -- June 05, 2006) -- Doctors at the Hadassah University Medical Center in Jerusalem have further refined groundbreaking computer-guided joint replacement surgery by replacing electro-optics with electro-magnetic technology. This new technology not only enhances precision in the operating room, but may also shorten the patient’s recovery period and hospital stay.
Prof. Iri Liebergall, head of Hadassah’s Orthopedic Departments, and Dr. Yoav Matan, director of the Joint Replacement Center at Hadassah University Hospital-Mt. Scopus hospital, who performed the world’s first computer-guided hip replacement operation two years ago, noted that electro-magnetic technology enables surgeons to operate without constantly considering the computer’s location. Most medical centers that perform computer-guided surgery use electro-optic technology, which requires the surgeons to maintain a continuous line of vision between the computer and the site of the patient’s surgery, forcing them to alter their location during the operation, prolonging the procedure.
"This new technology ensures that Hadassah will maintain its position as a world leader in computer-guided orthopedic surgery,” notes Prof. Liebergall, whose 12-person team performs about 600 joint replacements a year; 230 of them knee replacements. The new electro-magnetic technology has already been used in five operations. “We are proud that giant American corporations such as Zimmer and Medtronics, which developed these technologies, chose Hadassah in Jerusalem as a medical center to install and implement the latest refinement of their sophisticated computer navigation system."
Computer navigation systems provide surgeons with an accurate three-dimensional virtual picture of the surgical area continuously transmitted to a computer screen in front of them as they operate. Special sensors attached to the patient’s body convey data to the computer indicating the location of the surgical site relative to the space in which it is located. The data guides the surgeons in positioning the replacement through a display of the exact coordinates of the surgical site and angle at which the implant should be placed. This complex procedure is conducted through a minimal incision of two inches.
