Abstract
A surgical system comprises a magnet having a magnetic field. The magnet is disposed with a first spinal implant. A sensor is disposed with a first end of a second spinal implant. The sensor is configured to measure the magnetic field relative to the second spinal implant. Indicia represents position and orientation of the first spinal implant relative to the second spinal implant based on the measured magnetic field. Systems and methods are disclosed.
