Abstract:
1. An arrangement with an implant and attachment part, in which the attachment part comprises a recessed wall and the implant includes or cooperates with a substantially cylinder-shaped portion on a spacer sleeve applied to the implant, said substantially cylinder-shaped portion constituting front parts of a spacer arranged at or on upper parts of the implant, said attachment part and said recessed wall being arranged with displaceability in a main longitudinal direction of the implant relative to an outer surface of the substantially cylinder-shaped portion, said substantially cylinder-shaped portion being expandable so that, in a given position of longitudinal displacement, it is possible to achieve interaction between the outer surface of the substantially cylinder-shaped portion and the recessed wall and thus anchoring of the attachment part to the substantially cylinder-shaped portion, wherein: the substantially cylinder-shaped portion comprises parts extending adjacent to one another which, during expansion, can be pressed outward in a radial direction; the parts extending adjacent to one another are arranged with internal surfaces which combine to form an internal inner surface; the parts extending adjacent to one another are expandable by means of a fastening screw which is provided with an outer screw surface which can cooperate with said internal inner surface, said parts extending adjacent to one another being expanded radially as a function of a position of insertion of the screw in the implant; and the parts extending adjacent to one another have lengths which substantially correspond to or are slightly smaller than a total length of the spacer sleeve.
