Stereotactic Systems, Imageless, Surgical
Definition : Imageless computer-aided stereotactic systems designed to aid in the performance of minimally invasive surgical procedures. These systems use a navigation system that is not guided by images (i.e., imageless) but by registering and tracking appropriate anatomic reference points (i.e., landmarks). Imageless surgical systems provide surgeons with real-time, three-dimensional (3-D) positioning and orientation of surgical instruments relative to the patient's anatomy. They are similar to the systems that use image-guiding and these system provide surgical guidance without the need for pre- or intra-operative image acquisition, though registration is still necessary. Navigation is achieved by selecting specific anatomical parts or bone-implanted tracker pins intra-operatively as landmarks and using a reference pointer to create a reference frame for the computer model. Dedicated imageless surgical systems intended for particular specialties (e.g., orthopedics) and procedures (e.g., total knee or hip replacement and hip resurfacing) are available; dedicated software intended for imageless trauma procedures is also available.
