Abstract
An intervertebral implant in the form of a support unit with a central yoke and four legs extending in a direction is described. The legs are configured in two substantially mutually parallel planes spaced apart by the yoke and are abuttable as support surfaces against adjacent vertebrae. A guide cylinder extending from the yoke in the same direction as the legs has at least on threaded surface. A dilator member is adapted to be fixed to the guide cylinder and to deformably spread the legs of the intervertebral implant a predetermined amount. The gaps between the legs which the dilator member spreads may have grooves to arrest the dilator member in a predetermined location.
