Computer Assisted Surgery (CAS)
Computer assisted surgery has been used by surgeons for many years. There are many systems in use but the most common use a camera system to record the position of markers inserted into the hip during surgery to precisely locate where the components should be placed. Computer navigation also allows for the position of instruments and implants to be checked throughout surgery and adjusted as necessary.
An alternative to computer navigation is the use of computer planning from preoperative scans and the creation of customised jigs that guide Dr Negus in where to place the components. These are known as Patient Specific Implants or PSI.
