Navigation during hip surgery has the same purpose like navigation in a car: To reliably reach your destination – and thus reduce complications.
Digital planning
The orthopedic surgeon plans the operation as usual with the help of the X-ray image.
Navigated hip surgery
The Naviswiss navigation system helps the surgeon during the operation to insert the prosthesis as planned with great accuracy. The more precisely the prosthesis is inserted, the longer its service life and the lower the risk of complications.
Documented result
Finally, the results of the navigation are also used for quality control and documentation of the operation.

How does hip navigation work?

Just like in a car the driver, in hip navigation the orthopedic surgeon determines the destination before starting. The navigation system helps the surgeon to reach this destination during the operation. On the way, he has the possibility to deviate from the route at any time or to head for a different destination due to special individual circumstances.

1. Referencing
The surgeon temporarily fixes two NAVItags measuring trackers by means of small punctures on the pelvic crest and on the femur. These serve to measure the anatomy.
2. Navigation
When inserting the acetabular cup, the navigation system now shows the exact angle. This allows the orthopedic surgeon to decide on the optimal orientation.
3. Documentation
When inserting the hip stem, the navigation assists in adjusting the optimal leg length. Alignment and leg length are finally documented with a detailed surgical report.
