Expandable fusion device with integrated deployable retention spikes

A system of autonomously controlling an expandable implant comprising:

• an expandable implant comprising:
• a computing unit including a processor with memory housed within the implant;
• upper and lower main endplates configured to engage adjacent vertebrae;
• a plurality of force sensors housed in the upper and lower main endplates, wherein the force sensors are configured for load distribution measurement;
• an actuator assembly including a rotatable actuator having a shaft and a rotatable nut configured to cause an expansion in height of the upper and lower main endplates;
• a plurality of driving ramps positioned along the shaft of the actuator and engaged with the upper and lower main endplates;
• an electrical motor configured to rotate the actuator and/or the nut to move the driving ramps and expand the upper and lower main endplates;
• a sidecar assembly including a sidecar carrier, an upper carrier endplate pivotably coupled to an upper spike, and a lower carrier endplate pivotably coupled to a lower spike;
• a linear motor configured to move the sidecar carrier, to thereby deploy the upper and lower spikes;
• and
• a power supply for providing power to the motors;
• a robotic navigation system comprising a moveable end effector and a display;
• and
• an inserter positionable in the end effector and configured to hold the expandable implant, wherein the inserter includes an electromagnet that generates an electric field causing a plurality of hall effect sensors to detect a relative location of the driving ramps.
