Abstract:
1. A spinal anchoring device, comprising: a bone-engaging member adapted to engage bone, the bone-engaging member having a head formed thereon; a spinal fixation element; a U-shaped receiver member having a distal cavity that movably seats the head of the bone-engaging member and the U-shaped receiver member having a proximal recess that seats the spinal fixation element, the cavity and the recess including an opening extending therebetween and defined by the U-shaped receiver member, the opening further having a size that allows a portion of the spinal fixation element to extend into the distal cavity but prevents passage therethrough of the spinal fixation element seated in the proximal recess; and a fastening element adapted to mate to the U-shaped receiver member to lock the spinal fixation element relative to the U-shaped receiver member while allowing the U-shaped receiver member to move freely relative to the bone-engaging member.
