1. A surgical implant assembly for use in an implantation procedure performed on a functional spinal unit of a subject, the functional spinal unit comprising a superior vertebral bone, an inferior vertebral bone, and an intervertebral disc space disposed between the superior vertebral bone and the inferior vertebral bone, the surgical implant assembly comprising:
an implant sized and configured to be at least partially received in the functional spinal unit and a non-implantable insertion instrument configured to advance the implant to the functional spinal unit, the implant comprising:
a superior member, an exterior surface of the superior member configured to abut an inferior surface of the superior vertebral bone;
an inferior member, an exterior of the inferior member configured to abut a superior surface of the inferior vertebral bone;
a first side wall connecting the superior member and the inferior member; and
an internal cavity, at least a portion the internal cavity bordered by the superior member, the inferior member, and the first side wall; and
the non-implantable insertion instrument comprising:
a handle assembly comprising a body, the body extending from a front portion to an opposing back portion;
an implant delivery track coupled to the front portion of the handle assembly and comprising an upper surface, a lower surface, a distal portion, and a proximal portion, the implant delivery track extending from the proximal portion to the distal portion along a first longitudinal axis;
a distraction assembly disposed at the distal portion of the implant delivery track and extended outwardly therefrom, the distraction assembly comprising a first plate and a second plate, the first plate movable relative to the second plate along at least one direction that is non-parallel to first longitudinal axis of the implant delivery track, the distraction assembly configured to transition the first plate from a non-distracted configuration to a distracted configuration relative to the second plate; and
an implant pusher member movably coupled to the implant delivery track, the implant pusher member configured to advance the implant along at least a portion the implant delivery track and onto an implantation site of the subject;
wherein at least a portion of an interior surface the superior member of the implant is configured to engage with at least a portion of the upper surface of the implant delivery track, and at least a portion of an interior surface of the inferior member of the implant is configured to engage with at least a portion of the lower surface of the implant delivery track; and
wherein the implant is configured such that at least a portion of the implant delivery track can be seated within the internal cavity of the implant when the at least portion of the upper surface is engaged with the at least portion of the interior surface of the superior member and the at least portion of the lower surface is engaged with the at least portion of the interior surface of the inferior member.
