1. A system for performing spinal fusion surgery, the system comprising:
a tracking system for tracking one or more markers;
a computer processor;
a physical spinal rod having a length;
an inserter configured for insertion of the physical spinal rod; and
an engagement member;
wherein the rod inserter is configured for connecting to a proximal end of the physical spinal rod,
wherein the rod inserter comprises a first marker attached to the rod inserter,
wherein the engagement member comprises a second marker attached to the engagement member,
wherein the engagement member is configured to slideably engage with the physical spinal rod,
wherein the tracking system is configured to track the engagement member during movement of the engagement member from the proximal end to a distal end or from the distal end to the proximal end along a length of the physical spinal rod, and
wherein the computer processor is configured to determine an axis, a curvature, a shape or a combination thereof of the physical spinal rod based on tracking information of the engagement member in relationship to the spinal rod connected to the tracked rod inserter.
