Abstract
Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and/or derotating the spine and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

1-30. (canceled)
A spinal correction system comprising:
- a first rod configured to extend along a first side of a spine;
- a first stabilization member configured to extend along the first side of the spine, the first stabilization member configured to laterally constrain the first rod while allowing the first rod to slide axially and to change in pitch, yaw, and roll about a first pivot point;
- a first rod anchor configured to be secured to a vertebra of the spine and to laterally constrain the first stabilization member while allowing the first stabilization member to slide axially and to change in pitch, yaw, and roll about a second pivot point;
- a second rod anchor configured to be secured to a vertebra of the spine and to laterally constrain the first stabilization member while preventing the first stabilization member from sliding axially and from changing in pitch, yaw, and roll;
- a second stabilization member configured to extend along a second side of the spine;
- a third rod anchor configured to be secured to a vertebra of the spine and to laterally constrain the second stabilization member while allowing the second stabilization member to slide axially and to change in pitch, yaw, and roll about a third pivot point;
- and
- a fourth rod anchor configured to be secured to a vertebra of the spine and to laterally constrain the second stabilization member while preventing the second stabilization member from sliding axially and from changing in pitch, yaw, and roll.
