A push-in interbody spinal fusion (100) implant having an expandable height. The implant (100) comprises upper and lower members (102 and 106) with an expander in between (122). When the expander (122) is changed from one position to another, for example as in the first embodiment where it is rotated in a plane perpendicular to the axis of the upper and lower members (102 and 106), the height of the implant (100) is increased.
