1. An expandable intervertebral spacer system, the spacer system comprising:
a) a top plate having a top periphery and a top surface within the top periphery and a bottom plate having a bottom periphery and a bottom surface within the bottom periphery, wherein the top plate and bottom plate form a cage surrounding a cavity, wherein the cage has a proximal end and a distal end;
b) four locking mechanisms separating the top plate and bottom plate;
c) a stanchion comprising a movable post having saw teeth and a stationary post having saw teeth; and
d) a spring configured to bias the movable post against the stationary post, such that the movable post and stationary post cooperate to lock the top plate and bottom plate apart a desired distance.
