How it works
Research, and an understanding of biomechanics can tell us what anatomical configuration produces best results with orthopaedic surgical procedures, whether it be realignment procedures, implant surgery or joint stabilisation. Navigation allows surgeons to know precisely the position and orientation ofinstruments and implants in relation to the anatomy of the patient, like a virtual ruler and protracter. There are many systems that provide this information for the surgeon, the principles are the same in general
The Requirements: -
Trackers: - Devices whose orientation and position can be determined by either markers on the device or its effect on an electromagnetic field.
Detectors: - Intruments that can detect these devices' markers or the field effects, and thereby calculate their orienattion and position.
Anchors: - Mechanism for attaching the device to the bone, instrument or implant rigidly so that orientation of these can be deduced from the position of the attached devices.
The Process: -
