A method for implanting a spinal prosthesis, comprising:
- forming a passage from a first side of a lamina or a spinous process completely through to a second side of the lamina or the spinous process;
- advancing a distal end of a fastening element from the first side to the second side until a proximal stop of the fastening element rests against the first side;
- and
- securing a bearing prosthesis to the distal end of the fastening element by inserting the distal end of the fastening element into the bearing prosthesis, wherein the securing step is performed by expanding the fastening element into an opening in the bearing prosthesis.
