C.A.O.S

From Wikipedia, the free encyclopedia

With Computer Assisted Orthopedic Surgery or C.A.O.S, the surgeon can more accurately pinpoint anatomical landmarks that might be hard to see in a small incision. This navigation system then guides the surgeon through different bone cuts and finally to implantation. Computer Assisted Orthopedic surgery is mostly used in knee implant surgery because of the precision the surgeon get with femoral and tibial bone cuts. It is also used to navigate acetabular components placement where correct cup inclination is crucial.

Computer Assisted Orthopedic Surgery is a system where a computer interacts with body parts via infrared lights and gate detectors. There are systems that require C-Arm images or CAT scans, flourabased systems and the newest and most evolved systems are imageless systems, this means that no pre scans of any kind are necessary. The imageless systems are far less complicated, are lower cost and more patient friendly since the pre scans are not necessary. The imageless systems will also bring down operation time. The negative aspect of imageless systems is that they might be less accurate, this is yet to be proven.
