Abstract
An anchoring member is provided with a shaft 2, 12 for anchoring in a bone and a head 3, 53 with a substantially U-shaped cross-section for connection with a rod 9, 59, the head having a base 5, 55 connected with the shaft 2, 12 and two free legs 6, 7; 56, 57 forming a channel for receiving the rod 9, 59. The two legs have an internal screw thread 8, 58 and an external screw thread 8', 58'. A nut member 11, 61 comprises an internal thread which embraces the outside of the legs and cooperates with the external screw thread and a locking member 10 has a thread cooperating with the internal screw thread of the legs. The anchoring member further comprises a spring member 19, 79 acting onto the rod 9, 59 to be received in order to, on the one hand, obtain a rigid connection between the anchoring member and the rod and, on the other hand, to allow an easy manipulation for precisely adjusting the position between the anchoring member and the rod before finally locking the position.
