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.

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 transl
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; andlaterally coupling the first rod and the second rod such that the lateral coupling facilitates derotation and translation of the spine. 2. The method of claim 1, wherein the first and second anchors are secured to vertebra outside of an apical region of the spine, the method further comprising immobilizing an apical region of the spine and leaving a superior region of the spine adjacent to the apical region and an inferior region of the spine adjacent to the apical region free to move in at least one degree of freedom. 3. The method of claim 2, wherein the at least one degree of freedom facilitates elongation of the spine in the inferior-superior direction. 4. The method of claim 1, wherein laterally coupling the first rod and the second rod includes: securing the third anchor to a vertebra of the spine such that the third anchor extends from the second side of the spine toward the first side of the spine, a flexible connector being secured to the third anchor; andsecuring a first adjuster to the first rod, the first adjuster being secured to the flexible connector. 5. The method of claim 4, further comprising: adjusting an effective length of the flexible connector in order to move the vertebra connected to the third anchor toward the first rod; andafter adjusting the effective length, securing the second rod to the third and fourth anchors. 6. The method of claim 5, further comprising laterally translating and derotating the spine to correct a curvature of the spine and securing the corrected curvature of the spine by securing the second rod in the third and fourth anchors. 7. The method of claim 1, wherein the first and second anchors are secured to pedicles of different vertebrae. 8. The method of claim 1, wherein extending the first and second rods along the first and second sides of the spine, respectively, includes the first rod extending along a longer region of the spine than the second rod. 9. The method of claim 1, wherein extending the first and second rods along the second side of the spine includes the second rod generally corresponding in length to the apical region of the spine. 10. The method of claim 1, wherein securing the second rod to the third anchor includes receiving the second rod in a U-shaped head of the third anchor. 11. The method of claim 1, further comprising securing the first and second rods, respectively, to the spine with anchors that selectively prevent axial sliding and changes in pitch, yaw, and roll of the first and second rods, respectively. 12. A method of correcting a spinal deformity of a patient's spinal column, the method comprising: securing a first rod anchor to a first vertebra of the patient's spine;securing a second rod anchor to a second vertebra of the patient's spine;coupling a first rod to the first rod anchor and the second rod anchor such that: the first rod is laterally constrained relative to the first rod anchor while being free to slide axially and to change in alignment relative to the first rod anchor; andthe first rod is laterally constrained relative to the second rod anchor while being free to slide axially and to change in alignment relative to the second rod anchor;securing a third rod anchor to a third vertebra of the patient's spine, the third vertebra being different from the first vertebra;securing a fourth rod anchor to a fourth vertebra of the patient's spine, the fourth vertebra being different from the second vertebra;coupling a second rod to the third rod anchor and the fourth rod anchor such that: the second rod is laterally constrained relative to the third rod anchor while being free to slide axially and to change in alignment relative to the third rod anchor; andthe second rod is laterally constrained relative to the fourth rod anchor while being free to slide axially and to change in alignment relative to the fourth rod anchor; andcoupling the first rod with the second rod such that the coupling facilitates derotation and translation of the spinal deformity. 13. The method of claim 12, wherein the coupling between the first rod and the second rod prevents the first rod and the second rod from changing alignment with respect to each other. 14. The method of claim 12, wherein the first rod extends along a first side of the patient's spine and the second rod extends along a second side of the patient's spine opposite to the first side. 15. The method of claim 12, wherein a change in alignment comprises a change in one or more of pitch, yaw, and roll. 16. A method of correcting a spinal deformity of a patient's spinal column, the method comprising: securing a first rod anchor to a first vertebra of the patient's spine;securing a second rod anchor to a second vertebra of the patient's spine;coupling a first rod to the first rod anchor and the second rod anchor such that: the first rod is laterally constrained relative to the first rod anchor while being free to slide axially and to change in alignment relative to the first rod anchor; andthe first rod is laterally constrained relative to the second rod anchor while being free to slide axially and to change in alignment relative to the second rod anchor;securing a third rod anchor to a third vertebra of the patient's spine;securing a fourth rod anchor to a fourth vertebra of the patient's spine;coupling a second rod to the third rod anchor and the fourth rod anchor such that: the second rod is laterally constrained relative to the third rod anchor while being free to slide axially and to change in alignment relative to the third rod anchor; andthe second rod is laterally constrained relative to the fourth rod anchor while being free to slide axially and to change in alignment relative to the fourth rod anchor; andcoupling the first rod with the second rod such that the coupling facilitates derotation and translation of the spinal deformity, wherein one or more of the first, second, third, and fourth rod anchors provides for selective locking of one or more of pitch, yaw, and roll. 17. The method of claim 16, wherein the coupling between the first rod and the second rod prevents the first rod and the second rod from changing alignment with respect to each other. 18. The method of claim 16, wherein the first rod extends along a first side of the patient's spine and the second rod extends along a second side of the patient's spine opposite to the first side. 19. The method of claim 16, wherein a change in alignment comprises a change in one or more of pitch, yaw, and roll.
