A spinal correction system (100) comprising:a first rod (12) configured to extend along a first side of a spine；a first (16) and a second (18) rod anchors configured to be secured to a vertebra of the spine and 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 (P1) and a second pivot point (P2), respectively；a second rod (14) configured to extend along a second side of the spine；a third and a second rod anchors configured to be secured to a vertebra of the spine and to laterally constrain the second rod while allowing the second rod to slide axially and to change in pitch, yaw, and roll about a third pivot point and a fourth pivot point, respectively； anda transverse coupler extending laterally between the first and second rods, the transverse coupler laterally constraining the first and second rods and preventing the first and second rods from changing in pitch, yaw, and roll relative to the transverse coupler.
