Abstract

A spinal construct comprising a first portion. A second portion defines a longitudinal axis and is configured to penetrate tissue. A tether is fastened with the first portion such that a spinal implant connected with the tether is movable to a plurality of orientations relative to the longitudinal axis. Systems and methods are disclosed.

Claims (29)

1. A spinal construct comprising:

a first portion;

a second portion defining a longitudinal axis and being configured to penetrate tissue; and

a tether having a section positioned within the first portion such that the section is coaxial with the longitudinal axis and a spinal implant connected with the tether is movable to a plurality of orientations relative to the longitudinal axis,

wherein the first portion defines a cavity having the section disposed therein, the first portion comprising a wall circumferentially disposed about the cavity, the tether extending through the cavity.

2. A spinal construct as recited in claim 1 , wherein the plurality of orientations includes a plurality of axes and/or a plurality of planes.

3. A construct as recited in claim 1 , wherein the spinal implant is adjustable in a plurality of planes relative to the second portion.

4. A spinal construct as recited in claim 1 , wherein the cavity extends past an uppermost surface of the wall.

5. A spinal construct as recited in claim 1 , wherein the first portion includes an inner surface that defines the cavity, the inner surface being mechanically coupled to the section.

6. A spinal construct as recited in claim 1 , wherein the first portion is swaged to the section.

7. A spinal construct as recited in claim 1 , further comprising the spinal implant, wherein the spinal implant comprises a ring defining an opening, the tether being positioned within the opening.

8. A spinal construct as recited in claim 1 , wherein an outer surface of the section includes adhesive material to fix the section to the first portion.

9. A spinal construct as recited in claim 1 , wherein the first portion engages the section in a friction fit.

10. A spinal construct as recited in claim 1 , wherein the first portion engages the section in a pressure fit.

11. A spinal construct as recited in claim 1 , wherein an outer surface of the wall has a hexalobe geometry.

12. A spinal construct as recited in claim 1 , wherein the tether is resorbable.

13. A spinal construct as recited in claim 1 , wherein the tether is degradable.

14. A spinal construct comprising:

a bone fastener comprising a head including an inner surface that defines a cavity, and a shaft defining a longitudinal axis and being configured to penetrate tissue; and

a tether extending between a first end and a second end, the first end including a section that is positioned within the cavity such that the section is coaxial with the longitudinal axis and a spinal implant connected with the tether is movable to a plurality of orientations relative to the longitudinal axis,

wherein the first portion defines a cavity having the section disposed therein, the first portion comprising a wall circumferentially disposed about the cavity.

15. A spinal construct as recited in claim 14 , wherein an outer surface of the section includes adhesive material to fix the section to the head.

16. A spinal construct as recited in claim 14 , wherein the head engages the section in a friction fit.

17. A spinal construct as recited in claim 14 , wherein the head engages the section in a pressure fit.

18. A spinal construct comprising:

a first portion;

a second portion defining a longitudinal axis and being configured to penetrate tissue; and

a tether fastened with the first portion such that a spinal implant connected with the tether is movable to a plurality of orientations relative to the longitudinal axis,

wherein the first portion defines a circular cavity having the section disposed therein, the first portion comprising a wall circumferentially disposed about the cavity, the extending through an uppermost surface of the first portion, an outer surface of the wall having a hexalobe geometry configured for engagement with a similarly shaped tool.
