An intervertebral implant having an endplate that can be slidably expanded following its placement in the intervertebral space. The endplate comprises a pair of planks that are slidably received within respective recesses of a base portion of the endplate. During insertion of the implant into the intervertebral space, the planks are set in a contracted position within respective recesses of a base portion of the endplate. This provides the implant with a relatively small profile that is suitable for MIS procedures. Once the implant has been inserted, the planks are slid outward from the recesses to an expanded position that increases the footprint of the implant endplate. This expansion increases the stability of the implant.
