SPINAL CORRECTION AND SECONDARY STABILIZATION

摘要

Methods of correcting a spinal deformity include securing a first rod on a first side of a spine, securing a second rod on a second side of the spine, and securing a lateral coupling between the first rod and the second rod to facilitate derotation and translation of the spinal deformity and further provide stabilization of the corrected spine.

主权项

1. A method of correcting a spinal deformity, the method comprising:
extending a first rod along a first side of a spine of a patient; securing a first anchor to a vertebra of the spine; receiving the first rod with the first anchor such that the first rod is secured against substantial lateral translation relative to the first anchor and the first rod is allowed to slide axially relative to the first anchor through a first pivot point and to change in at least two of pitch, yaw, and roll about the first pivot point during correction; securing a second anchor to a vertebra of the spine; receiving the first rod with the second anchor such that the first rod is secured against substantial lateral translation relative to the second anchor and is allowed to change in at least pitch and yaw about a second pivot point during correction; extending a second rod along a second side of the spine of the patient; securing a third anchor to a vertebra of the spine; receiving the second rod with the third anchor such that the second rod is secured against substantial lateral translation relative to the third anchor during correction and such that the second rod is secured against changes in pitch, yaw, roll, and axial sliding; securing a fourth anchor to a vertebra of the spine; receiving the second rod with the fourth anchor such that the second rod is secured against substantial lateral translation relative to the fourth anchor; and laterally coupling the first rod and the second rod such that the lateral coupling facilitates derotation and translation of the spine.
