An anchoring member and packer for use in spinal osteosynthesis systems. The anchoring member can accept a connecting element such as a spinal rod, and is adapted for insertion into bone. The packer provides stability to the anchoring member particularly when the anchoring member is not fully engaged to bone. The anchoring member has a head, anchoring means for engagement to bone, and retaining means for retaining the packer against the head. The packer has a through-orifice for receiving the anchoring member and complimentary retaining means for engagement to the head of the anchoring member.
