1. An interbody spacer for a spine comprising:
an elongated threaded shaft having a first end opposite a second end;
a first spring loaded ramp coupled to the first end of the elongated threaded shaft;
a second spring loaded ramp coupled to the second end of the elongated threaded shaft,
wherein the first spring loaded ramp and the second spring loaded ramp comprise an open position and a closed position and are spring loaded to maintain the closed position;
a first driving wedge threadably engaged with the first end of the elongated threaded shaft; and
a second driving wedge threadably engaged with the second end of the elongated threaded shaft,
wherein the first driving wedge is configured to drive the first spring loaded ramp and the second driving wedge is configured to drive the second spring loaded ramp to maintain a first distance between a first vertebra and a second vertebra, wherein the first distance corresponds to a maximum height of the interbody spacer and of the first spring loaded ramp and the second spring loaded ramp.
