1. A kit, comprising:
a spacer comprising a body with a distal portion and a plurality of notches defined by the body, a first arm attached to the distal portion of the body, a second arm attached to the distal portion of the body, and an actuator coupled to the body, wherein movement of the actuator in a first direction causes the first arm of the spacer to deploy and move toward engagement with a first vertebra of a subject and the second arm of the spacer to deploy and move toward engagement with a second vertebra of the subject, wherein, for each of the notches, to define the notch the body comprises a planar, proximal wall extending distally and radially inset relative to portions of the body immediately adjacent to, and in contact with, the planar, proximal wall and an undercut region providing an opening immediately distal to, and radially undercut relative to, the planar, proximal wall; and
an insertion instrument comprising an instrument shaft having a distal end portion and a proximal end portion, a plurality of prongs extending from the distal end portion of the instrument shaft and configured for engaging the notches defined in the body of the spacer throughout deployment of the first and second arms and engagement of the first and second arms with the first and second vertebrae, respectively, and a drive element extending along the instrument shaft and configured to engage the spacer and move the actuator in the first direction, wherein at least a portion of each of the prongs is configured for insertion into the distal undercut region of a one of the notches.
