What is navigation-guided surgery?

Navigation-guided surgery is performed with the help of a computer programme which, using a CT scan and an X-ray of the patient, creates 3D images of the spine, allowing the specialist to perform the surgery with excellent precision.

In cases where this system is used, the patient undergoes a CT scan in the Diagnostic Testing Department as well as an X-ray (front and side view) in the operating theatre. With both tests, the computer system composes a 3D image of the actual moment when the operation begins.

Using specific instruments and laser cameras recognised by the computer programme, the specialist can perform the surgery more precisely and accurately, placing the screws with a margin of error of less than 1.5 mm, in other words, with 99.5% accuracy.
