The spinal rod is disposed within a saddle portion of a housing of the bone screw, and includes an elongated body having a first end and a second end. The spinal rod is formed from a first material having a first modulus of elasticity. The flexible member is coupled to the spinal rod, and includes an elongated body having a first end portion and a second end portion. The flexible member is formed from a second material having a second modulus of elasticity that is different from the first modulus of elasticity. The fixation member includes a threaded body portion and a head portion defining a hole therethrough. A portion of the flexible member extends through the hole of the head portion. ## Claims ### Claim 1 A spinal fixation construct comprising: a first fixation member attached to a first vertebral body; a second fixation member attached to a second vertebral body; a third fixation member attached to a third vertebral body; and a band connected to at least one of the fixation members and another vertebral body. ### Claim 2 (depends on 1) The spinal fixation construct of claim 1, wherein the first fixation member is a first bone screw including a first rod passage. ### Claim 3 (depends on 2) The spinal fixation construct of claim 2, further comprising a rod disposed in the first rod passage. ### Claim 4 (depends on 3) The spinal fixation construct of claim 3, wherein the band extends through a passage in the rod. ### Claim 5 (depends on 3) The spinal fixation construct of claim 3, wherein the second fixation member is a second bone screw including a second rod passage. ### Claim 6 (depends on 5) The spinal fixation construct of claim 5, wherein the rod is disposed in the second rod passage. ### Claim 7 (depends on 6) The spinal fixation construct of claim 6, wherein the first and second bone screws are pedicle screws. ### Claim 8 (depends on 1) The spinal fixation construct of claim 1, wherein the band is flexible. ### Claim 9 (depends on 1) The spinal fixation construct of claim 1, wherein the band extends above the first and second bone screws. ### Claim 10 A spinal fixation construct comprising: first and second bone screws defining respective first and second rod passages, the first and second bone screws attached to a first vertebral body; first and second spinal rods including respective first and second single longitudinal axes and first and second apertures formed therethrough, a portion of the first rod positioned within the first rod passage and a portion of the second rod positioned within the second rod passage; first and second fixation members attached to a second vertebral body; and first and second bands connected to the first and second screws and first and second fixation members, respectively. ### Claim 11 (depends on 10) The spinal fixation construct of claim 10, wherein the first and second longitudinal axes are substantially parallel to each other. ### Claim 12 (depends on 10) The spinal fixation construct of claim 10, further comprising third and fourth bone screws including respective third and fourth rod passages, the third and fourth bone screws attached to a third vertebral body. ### Claim 13 (depends on 12) The spinal fixation construct of claim 12, wherein a portion of the first spinal rod is positioned within the first and third rod passages and a portion of the second spinal rod is positioned within the second and fourth rod passages. ### Claim 14 (depends on 10) The spinal fixation construct of claim 10, wherein the band is flexible. ### Claim 15 A spinal fixation construct comprising: a first rod attached to a first vertebral body; a first fixation member attached a second vertebral body; and a band connected to the first rod and the first fixation member. ### Claim 16 (depends on 15) The spinal fixation construct of claim 15, wherein the first spinal rod is attached to the first vertebral body with a first bone screw. ### Claim 17 (depends on 16) The spinal fixation construct of claim 16, wherein the first spinal rod is attached to a third vertebral body with a second bone screw. ### Claim 18 (depends on 17) The spinal fixation construct of claim 17, wherein the band is attached to fourth vertebral body with a second fixation member. ### Claim 19 (depends on 15) The spinal fixation construct of claim 15, wherein the band extends through a first passage in the first spinal rod. ### Claim 20 (depends on 15) The spinal fixation construct of claim 15, wherein the band is flexible.
