An interbody fusion device including pivoting endplates is disclosed. The endplates define grooves between the endplates to house sliding pins. A threaded shaft extends through the implant to connect the endplates and the sliding pins. The implant is fit to be inserted into an intervertebral disc space to pivot according to the natural angles of the adjacent vertebrae. The shaft can be rotated to adjust the sliding pins into a position to provide support to the endplates at the angle they take between the vertebrae.
