1. An expandable implant comprising:
an expandable spacer including:
upper and lower endplates configured to engage adjacent vertebrae;
an actuator assembly including a rotatable actuator having a shaft;
a plurality of driving ramps positioned along the actuator shaft, wherein the upper and lower endplates are engaged with the plurality of driving ramps such that actuation of the actuator assembly causes movement of the driving ramps to thereby expand the upper endplate relative to the lower endplate;
a strain gauge embedded in at least one of the endplates and configured to measure force being applied to the expandable implant by a vertebral body,
first and second expandable spacers; and
the expandable implant further comprising a link plate pivotally coupled to the first and second expandable spacers.
