    摘要： A bone anchoring device with a shank (2, 102, 202) to be anchored in a bone or vertebra, a head (3, 103, 203), and a receiving part (4) receiving the head (3, 103, 203) for connecting the shank (2, 102, 202) to a rod is provided. The shank (2, 102, 202) and the head (3, 103, 203) are separate parts. The head (3, 103, 203) has a bore (31, 131, 231) with a cylindrical inner surface, a ring-shaped groove (34, 134, 234) provided on the inner surface, and at least one slit (35, 135, 235) extending from the inner surface to the outer surface (30, 130, 230) of the head (3, 103, 203). The shank (2, 102, 202) has a first portion (21, 121, 221) for anchoring in the bone or vertebra and a second portion (23, 123, 223) with a cylindrical outer surface adjoining a free end (27, 127, 227). A projection (7, 107) is provided on the cylindrical outer surface which engages with the ring-shaped groove (34, 134, 234) of the head (3, 103, 203), when the cylindrical second portion (23, 123, 223) of the shank (2, 102, 202) is inserted in the bore (31, 131, 231) of the head.

    摘要： A bone screw is provided including
    a tubular body (1) having a first end (2) and a second end (3), wherein the tubular body has a tubular wall defining a cavity and wherein a plurality of openings are provided extending through the tubular wall into the cavity;
    an exterior bone thread on an exterior tubular surface of the tubular wall;
    a head (8) configured to engage with a driver to advance the bone screw in the bone by rotating the driver in a first direction, the head being also configured to connect to the tubular body at the first end (2);
    wherein the head is connectable to the tubular body in such a way that it is locked against disconnection from the tubular body when the driver is rotated in a second direction opposite to the first direction.
