The osteosynthetic fixation element (10) in the form of a pedicular screw or a vertebral column hook has a lower section (2) that can be anchored into a bone and an upper section (3) connected in the direction of its longitudinal axis (1), that is completely penetrated transversely by a penetration channel (8) running transversely to the longitudinal axis (1) for acceptance of a longitudinal support (40). The upper section (3) is provided with an internal threading (5) and an external threading (9) to accept a locking part (30; 50) locking the longitudinal support (40). The upper section (3) is provided at its upper end (6) or at the inserted lock part (30; 50) with a rotationally-stable, releasable connecting mechanism (4, 5, 7; 11, 12) for positive and non-positive temporary acceptance of a manipulation device (20).
An osteosynthetic fixation element comprising a shaft having a longitudinal axis, a lower section for attachment to a bone, an upper section having a penetration channel running transversely to said axis to receive a longitudinal support, and a locking part to secure a longitudinal support in said channel, said upper section being threaded to receive said locking part, said upper section further comprising a mechanism for receiving a manipulation device, said mechanism not interfering with said penetration channel and allowing a releasable and a rotational and tension stable connection with said manipulation device.
