主权项 1. A spinal stabilization system for providing stabilization between a first vertebra and a second vertebra comprising: a first anchor configured to engage with the first vertebra, wherein the first anchor includes a first receiver member of which includes a first receiver passage through the first receiver member; a second anchor configured to engage with the second vertebra, wherein the second anchor includes a second receiver member of which includes a second receiver passage through the second receiver member; a tension member including a body and a passage through the body that extends between a first end of the tension member and a second end of the tension member that is opposite from first end of the tension member, wherein the tension member is coupled within the first receiver member near the first end and is coupled within the second receiver member near the second end, a compression member including first and second ends positioned within the passage through the body of the tension member, and the compression member is not received within the first receiver passage of the first receiver member or configured to extend the distance between the first and second anchor such that the second receiver member when the tension member is coupled to the first receiver member and the second receiver member wherein the first and second ends of the tension member are crimped to collapse the passage when coupled within the first and second receiver passages respectively, and wherein the tension member with the compression member positioned therein are configured to resist movement of the first vertebra and the second vertebra away from and toward one another respectively by abutting both the first anchor and the second anchor resulting from the compression member extending the distance between the anchors from within a portion of the tension member.
