In order to eliminate pain or disability caused by a damaged
joint (for example, knee or hip), orthopaedic surgery is sometimes performed to replace the faulty joint with an orthopaedic implant. Less than perfect alignment of implants with
the joint can cause pain, longer recovery times, and possibly result in the procedure being repeated, however, precise alignment of orthopaedic implants is difficult to achieve
with consistency.
Integrating the Polaris Spectra® Optical Measurement System into an orthopaedic image-guided surgery solution would improve the consistency of implant alignment and precise anatomical and biomechanical reconstruction. It also helps reduce the invasiveness of the overall procedure, by providing surgeons with better real-time visualization tools.
How
can the integration of the Polaris Spectra achieve these improvements to orthopaedic procedures? Attaching NDI markers to limbs and surgical
instruments, and tracking them with the Polaris Spectra Position Sensor, results in the ability to identify the exact location and orientation of
these items in real-time. With the exact location of the bone and tools known, the surgeon can more accurately prepare the joint fixation point for the implant, as well as more
precisely align the artificial joint replacement into the implant fixation, resulting in optimal implant placement.
Key benefits of integrating the Polaris Spectra optical measurement system into an orthopaedic computer-assisted surgical application, include:
