DEVICE AND METHOD FOR CORRECTING A SPINAL DEFORMITY
First Claim
1. A correction system for a spine having an abnormal curvature, the spine including an upper vertebra, a lower vertebra, and an intermediate vertebra, the intermediate vertebra having a translational and rotational orientation and being located between the upper and lower vertebrae, the system comprising:
- a rod having a longitudinal axis, a first portion, a second portion, and a medial portion between the first and second portions;
a first rod anchor adapted to couple the first portion of the rod to the upper vertebra;
a second rod anchor adapted to couple the second portion of the rod to the lower vertebra; and
a stabilizer adapted to form a connection between the intermediate vertebra and the medial portion of the rod, wherein the stabilizer is adjustable to vary a distance between the intermediate vertebra and the medial portion of the rod, wherein the stabilizer is configured to alter the rotational and translational orientation of the intermediate vertebra.

Abstract
A device and method for correcting a spinal deformity are provided. A spinal implant for correcting a spinal deformity includes a multipoint connector that connects to at least one vertebra of a spine at a plurality of locations and a force directing device that applies a force to the vertebra through the multipoint connector. The force directing device may include a rod which extends generally along an axis of the spine and a force directing member which is adjustably coupled to both the rod and the multipoint connector and which applies a corrective force to the at least one vertebra.
