A push-in orthopedic implant having an expandable height. The implant includes an upper member, a lower member, and a blocker pivotally attached to one of the upper and lower members. The blocker is attached proximate one of the proximal and distal ends of the one of the upper and lower members, and is adapted to pivot into cooperative engagement with another of the one of the upper and lower members. The blocker is adapted to hold at least a portion of the upper and lower members apart so as to maintain an increased height of the implant and resist the collapse of the implant to a collapsed implant height when the implant is in a final deployed position.
