Abstract
Abstract The implant is inserted between two vertebrae of a spinal column. It has top and bottom supporting surfaces (11,12) from which one or more retractable anchor bolts (8) protrude. The drive mechanism extending the bolts is formed by an instrument or part of one, typically consisting of a wedge or rotary cams. The camshaft (18) can turn in a bore between the supporting surfaces, and is ventrally accessible. The shaft end can contain a tapped drilling or other device for engagement by the instrument. Where there are several cams on the shaft there can be discs between the cams and protruding beyond them, forming bearings for the shaft.
