An intervertebrae implant comprises two spaced sidewalls 1, 2, a front wall connecting the sidewalls at one end thereof, a back wall connecting the other end of the sidewall and corresponding apertures in the bottom and top surfaces extending transversely to the above-defined walls. In order to lock the implant in a desired position between two adjacent vertebrae a screw 13, 13' is rotatably provided in the front or back wall 3, 4, resp., and adapted to have a portion projecting beyond the bottom or top surface, resp., in a first rotational position and no projecting portion in a second rotational position.
