A surgical cutting tool for keyhole surgery comprises: a handle 2 at a proximal end of the tool; an elongate member 4 extending from the handle to a distal end of the tool; and a saw 6 at the distal end of the tool, the saw being supported by the elongate member 4. The elongate member 4 has a length allowing for insertion of the saw 6 into the body by a distance of at least 150 mm. The tool is arranged for insertion of the saw 6 into the body during keyhole surgery; and the saw 6 is able to cut bone when pressed against the bone.
