摘要：
Bone anchors are provided that include a distal shaft for engaging bony structure of a vertebral body and a proximal post pivotably mounted at or near the proximal end of the shaft during implantation of the bone anchor. The bone anchors include a locking member that is engageable to the post and to the shaft to lock the post in a selected angular orientation relative to the shaft.
