1. An expandable intervertebral implant system configured to be positioned in an intervertebral space between rostral and caudal vertebral bodies and expanded in situ in the intervertebral space, the system comprising:
an expandable implant having a length, a height, and a width, wherein the expandable implant defines a rostral plate with a rostral surface and defines a caudal plate with an opposite caudal surface each having a plurality of spikes configured and positioned for engaging the rostral and caudal vertebral bodies when the expandable implant is positioned in the intervertebral space and expanded, wherein the rostral and caudal plates comprise titanium and the plurality of spikes also comprise titanium, wherein the width is defined as a distance between the rostral surface and the caudal surface and the length is defined as a longest distance across the rostral surface of the expandable implant from a first end to a second end in a direction perpendicular to a direction of the width of the expandable implant, wherein the expandable implant comprises first and second posts between the rostral surface and the caudal surface that extend in a direction of the width of the expandable implant and that allow the expandable implant to expand in a direction of the width so as to increase the width between the rostral surface and the caudal surface of the expandable implant, wherein the expandable implant has an expandable liquid chamber that is positioned between the rostral surface and the caudal surface, wherein the expandable implant has a port fluidly connected to the expandable liquid chamber such that liquid injected through the port flows into the expandable liquid chamber between the rostral surface and the caudal surface; and
a source syringe configured to be connected to the port of the expandable implant and to inject and fill the expandable liquid chamber with a liquid from the source syringe that flows from the source syringe through the port and into the expandable liquid chamber.
