Abstract:
An anchoring device for urging a ligament against a bone surface within a tunnel formed in a bone of a patient comprising a first component and a second component, the first and second component being designed for mutual sliding co-operation between a first anchor inserting position and a second fixation position, said sliding co-operation being provided along respective parallel inner mating surfaces of each component which surfaces are each in angular relation to the respective component outer surfaces and in opposed angular relation to each other so that in the anchor insertion position the width of the said anchoring device is in an elongate narrow mode with respect to a bone hole and, in the fixation position, the width of said anchoring device is in a compressed wide mode to thereby urge the ligament against a wall of the bone hole wherein the first or second component has an elongate tongue and the second or first component respectively has an accommodating elongate groove wherein the tongue slides in the groove between the said anchor inserting and fixating positions and wherein the groove comprises a terminal abutment at a leading end, said terminal abutment being the end adjacent to the inner end of the bone hole, in use, to provide a limit of longitudinal compression of the trailing component of the anchor device.
