1. The vertebra body bracket consists of a threaded housing with elements secured inside, which are equipped with terminals penetrating into the front layers of neighbouring vertebrae bodies, and of screws. Unique characteristics: The housing (1) has the form of a perforated bush with an internal thread. At one end, it ends with an internal recess (3), which accommodates the cylindrical part (5) of the bush (4, 4'), equipped with the circumferential groove (6). The bush is equipped with the flange (7, 7'), resting against the front surface of the housing (1). The bush is protected against separation from the housing (1) with at least one screw (9). At the other threaded end, the housing (1) is connected with the perforated bush (11). The latter has the internal thread (12) at one side, and the flange (13) at the other side. The flange is equipped with anchoring protrusions (14) at its front side.
