The reduction member is translatable relative to the tether to dispose the spinal rod with a fastener configured for penetrating tissue. Systems and methods are disclosed. ## Claims ### Claim 1 A spinal construct comprising: a fastener comprising a shank configured for penetrating tissue and a head having a U-shaped inner surface that defines a passageway; a tether having an end connected to a concave portion of the inner surface such that the end is fixed to the fastener and disposed within the passageway; a spinal rod; and a reduction member connected with the spinal rod and engageable with the tether, the tether being connected to the spinal rod, the reduction member being translatable relative to the tether to dispose the spinal rod within the passageway. ### Claim 2 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member comprises a ratchet engageable with the tether. ### Claim 3 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member comprises a crimp that resists movement of the reduction member in at least one direction. ### Claim 4 (depends on 3) A spinal construct as recited in claim 3, wherein the crimp includes an inner surface having at least one penetrating element engageable with the tether to resist movement in the at least one direction. ### Claim 5 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member is translatable in a first axial direction and translation of the reduction member is resisted in a second axial direction. ### Claim 6 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member includes a connector defining a cavity configured for disposal of the spinal rod and coupling the spinal rod with the tether. ### Claim 7 (depends on 1) A spinal construct as recited in claim 1, wherein the spinal rod includes a first end attached with a bone screw configured to be fixed with vertebrae and a second end connected with the fastener. ### Claim 8 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member comprises a first inner surface that defines a cavity and a second inner surface that defines a passage, the spinal rod being disposed in the cavity and the tether being disposed in the passage, the first inner surface being spaced apart from the second inner surface. ### Claim 9 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member comprises a first inner surface that defines a cavity and a second inner surface that defines a passage that is spaced apart from the cavity, the spinal rod being disposed in the cavity and the tether being disposed in the passage. ### Claim 10 (depends on 1) A spinal construct as recited in claim 1, wherein the tether is resorbable. ### Claim 11 (depends on 1) A spinal construct as recited in claim 1, wherein the tether has a flexible configuration. ### Claim 12 (depends on 1) A spinal construct as recited in claim 1, wherein the tether has a rigid configuration. ### Claim 13 (depends on 1) A spinal construct as recited in claim 1, wherein the tether has a uniform thickness. ### Claim 14 (depends on 1) A spinal construct as recited in claim 1, wherein the reduction member comprises a first arcuate arm and a second arcuate arm, the arms defining a cavity therebetween, the cavity having the spinal rod positioned therein, the arms being movable relative to one another to expand and contract the cavity. ### Claim 15 A spinal implant system comprising: a fastener comprising a threaded shank configured for penetrating tissue and a head having a U-shaped inner surface defining a passageway; a tether having an end directly connected to a concave portion of the inner surface such that the end is fixed to the head, the tether extending away from the shank; an implant; and a reduction member connected with the implant and engageable with the tether such that the reduction member is movable in a first direction relative to the tether to translate the implant within the passageway and prevented from movement in a second direction. ### Claim 16 (depends on 15) A spinal implant system as recited in claim 15, wherein the reduction member comprises a tensioning device engageable with the tether. ### Claim 17 (depends on 16) A spinal Implant system as recited in claim 16, wherein the tensioning device includes a ratchet that draws the tether through the tensioning device. ### Claim 18 A spinal construct comprising: a fastener comprising a shank configured for penetrating tissue and comprising a head having a U-shaped inner surface that defines a U-shaped passageway; a spinal rod; a tether comprising an end that is connected directly to a concave portion of the inner surface and disposed within the passageway, the tether extending away from the fastener such that the tether is coaxial with the fastener; and a reduction member comprising a cavity having the spinal rod disposed therein and a passage having the tether disposed therein, the tether being connected to the spinal rod, the cavity being spaced apart from the passage, the reduction member being translatable relative to the tether to dispose the spinal rod within the passageway. ### Claim 19 (depends on 18) A spinal construct as recited in claim 18, wherein the cavity extends perpendicular to the passage. ### Claim 20 (depends on 18) A spinal construct as recited in claim 18, wherein an end of the tether is directly connected to the fastener such that the end is fixed to the fastener within the passageway.
