Abstract

A spinal correction system comprises an elongate member extending between a first end including a first inner surface defining a first cavity and a second end including a collar having a second inner surface defining a second cavity. The second cavity is movable relative to the elongate member in at least one orientation. The second end defining an elongated cavity. A first extender defines a first outer surface and a second extender defines a second outer surface. The elongate member is disposable between a first configuration and a second configuration such that the second cavity is movable in the at least one orientation to a position such that the first inner surface is forcibly disposable in a fixed engagement with the first outer surface and the interior surface is forcibly disposed in a fixed engagement with at least a portion of the collar. Methods of use are disclosed.

Claims (22)

1. A spinal correction system comprising:

at least one elongate member defining a longitudinal axis and extending between a first end and a second end, the first end including a first inner surface defining a first cavity that is fixed relative to the elongate member and the second end including a collar having a second inner surface defining a second cavity, the second cavity being movable relative to the elongate member in at least one orientation, the second end comprising an interior surface defining an elongated cavity;

at least one first extender defining a first outer surface that engages the first inner surface; and

at least one second extender defining a second outer surface configured for engagement with the second inner surface,

wherein the at least one elongate member is disposable between a first configuration and a second configuration such that the second cavity is selectively movable in the at least one orientation to a position such that the first inner surface is forcibly disposable in a fixed engagement with the first outer surface and the interior surface is forcibly disposed in a second fixed engagement with at least a portion of the collar;

wherein the first and second inner surfaces include a plurality of projections defining a plurality of recesses therebetween, such that in the second configuration, the collar is disposed in one of the plurality of recesses.

2. The system as recited in claim 1 , wherein the fixed engagement includes a pivot coupling between the first inner surface and the first outer surface.

3. The system as recited in claim 1 , wherein the elongated cavity includes a slot and the collar includes a post configured for fixation with the interior surface.

4. The system as recited in claim 1 , wherein the collar includes a hinge having a post configured to fix the collar with the elongated member in the position.

5. The system as recited in claim 1 , wherein the interior surface includes a scalloped configuration.

6. The system as recited in claim 1 , wherein the second cavity defines a second axis oriented transverse and is movable relative to the longitudinal axis.

7. The system as recited in claim 1 , wherein the at least one orientation includes an angular orientation and an axial orientation relative to the longitudinal axis.

8. The system as recited in claim 1 , further comprising at least one handle attached with the at least one elongate member.

9. The system as recited in claim 1 , wherein the first end includes a collar defining an opening extending therethrough and the collar of the second end includes a flange configured for engaging the second extender.

10. The system as recited in claim 1 , wherein the collar includes a shoulder configured for preventing ventral translation of the second extender.

11. The system as recited in claim 1 , wherein the first extender comprises a locking collar configured for engaging the first end of the at least one elongate member.

12. The system as recited in claim 1 , wherein the first extender is configured for disposal with a concave portion of a spine and the second extender is configured for disposal with a convex portion of the spine.

13. The system as recited in claim 1 , wherein the system is configured for derotation of vertebrae such that a first force oriented in a first direction is applied to the first end and a second force oriented in a second direction is applied to the second end.

14. The system as recited in claim 1 , wherein the at least one elongate member includes a plurality of elongated members disposed in a linked configuration.

15. The system as recited in claim 14 , wherein each of the elongate cavities of the second end are configured for disposal of a link member for linking the elongated members.

16. The system as recited in claim 1 , wherein the at least one elongated member includes a frame and the first inner surface defines a plurality of first cavities configured for disposal of a plurality of first extenders and the second inner surface defines a plurality of second cavities configured for disposal of a plurality of second extenders.

17. The system as recited in claim 16 , wherein the plurality of first cavities and the plurality of second cavities are aligned in a transverse orientation relative to the longitudinal axis.
