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