A spinal implant comprising an elongate body insertable between adjacent vertebrae, the elongate body comprising first and second portions, the first and second portions each having an internal surface, the internal surface of the first portion facing the internal surface of the second portion in use, at least part of each internal surface of the first and second portions being threaded, the spinal implant further comprising a bolt, at least part of the bolt being externally tapered and externally threaded, the external threads of the bolt corresponding with the threads of the internal surfaces of the first and second portions, wherein the bolt is insertable between the first and second portions of the elongate body such that the external threads of the bolt engage with the internal threads of the elongate body, whereby rotation of the bolt in the threaded internal surfaces of the first and second portions causes relative movement of first and second portions away from one another.
