Abstract
Official abstract text for this publication.
Spinal anchoring methods and devices are provided that are effective to correct spinal deformities while allowing some flexibility to the spinal. In particular, the methods and devices allow a spinal fixation element to mate to several adjacent vertebrae to maintain the vertebrae at a fixed distance relative to one another, yet to allow the orientation of each vertebrae relative to the fixation element to adjust as the orientation of the patient's spine changes.
First claim
Opening claim text (preview).
What is claimed is: 1. A spinal anchoring device, comprising: a bone screw having a threaded shank and a head with a flattened proximal surface; a receiver member having opposed side walls that define a U-shaped recess therebetween for receiving a spinal fixation element, a distal cavity formed therein that seats the head of the bone screw such that the threaded shank extends distally from a distal portion of the receiver member, and a protrusion formed on an inner surfac…
