Abstract
An anchoring element with a screw (12) comprising a threaded section (13) and a head (15) designed as a spherical segment-shaped section, and with a receiving portion (1) for connecting the screw (12) to a rod (19), is provided. The receiving portion (1) comprises a first end (2) and a second end (3) opposite the latter and a longitudinal axis (4) passing through the two ends (2, 3). The receiving portion further comprises a bore (5) coaxial with the longitudinal axis (4), a first region adjoining the first end (2) with an essentially U-shaped cross-section (18) with two free arms (8, 9) comprising a thread for receiving the rod (19) to be inserted, a region adjoining the other end (3) for receiving the head (15), and an element which exerts pressure on the rod (19) or on the head (15). In order that the screws can be used in situ for very different lengths, the threaded section (13) and the head (15) are designed as separate parts.
