Spinal correction system and method
A spinal construct comprises a first member engageable with a receiver of a first fastener having a shaft fixed with tissue. A second member is engageable with a receiver of a second fastener having a shaft fixed with the tissue. A longitudinal element connects the members. At least one of the members includes a mating element that is releasably engageable with a surgical instrument to manipulate the tissue such that movement of the receivers relative to the shafts is resisted and/or prevented. Surgical instruments, implants, systems and methods are disclosed.
1. A spinal construct comprising:
a longitudinal element;
a first arm connected with the longitudinal element;
a first body connected with the first arm such that the first body is rotatable relative to the first arm, the first arm including a lock to fix the first body relative to the first arm, the lock of the first body including a collar and a shaft that support the first arm, the collar defining an opening and the shaft defining an opening, the openings being aligned to support the first arm;
a second arm connected with the longitudinal element and axially translatable relative to the first arm, the second arm including a housing;
a second body connected with the second arm such that the second body is rotatable relative to the second arm, the second arm including a lock to fix the second body relative to the second arm; and
a locking element pivotably coupled to the housing and configured to move between a first orientation in which the second arm is translatable along the longitudinal element and a second orientation in which the second arm is prevented from translating along the longitudinal element.
2. A spinal construct as recited in claim 1 , wherein the longitudinal element is monolithically formed with first arm.
3. A spinal construct as recited in claim 1 , wherein the longitudinal element comprises a top surface having a plurality of splines engageable with the locking element when the locking element is in the second orientation.
4. A spinal construct as recited in claim 3 , wherein the longitudinal element comprises a bottom surface opposite the top surface, the bottom surface being free of splines.
5. A spinal construct as recited in claim 1 , wherein the collar includes a spline surface engageable with the first body to fix the first body relative to the first arm in the first orientation.
6. A spinal construct as recited in claim 1 , wherein the shaft includes a screw engageable with the first arm to fix the first body relative to the first arm in the second orientation.
7. A spinal construct as recited in claim 1 , wherein the first body includes a sleeve that defines a cavity for capture of a first fastener.
8. A spinal construct as recited in claim 1 , wherein the first body includes a mating element having a quick release connection with a first fastener.
9. A spinal construct as recited in claim 1 , wherein the first body includes at least one releasably engageable latch connectable with a mating element of a first fastener.
10. A spinal construct as recited in claim 1 , wherein the first body includes a pair of resiliently biased latches connectable with a mating element of a first fastener.
11. A spinal construct as recited in claim 10 , wherein the latches are biased to a capture position.
12. A spinal construct as recited in claim 1 , wherein the longitudinal element has a polygonal cross-sectional configuration.
13. A spinal construct comprising:
a surgical instrument including a first arm that is axially translatable relative to a second arm, the arms being connected with and rotatable relative to a longitudinal element;
a first sleeve directly connected with the first arm and engageable with a first fastener, the first sleeve being rotatable relative to the first arm in a first orientation and a second orientation, the first sleeve including a lock to fix the first sleeve relative to the first arm, the lock of the first sleeve including a collar and a shaft that support the first arm, the collar defining an opening and the shaft defining an opening, the openings being aligned to support the first arm;
a second sleeve directly connected with the second arm and engageable with a second fastener, the second sleeve being rotatable relative to the second arm in a first orientation and a second orientation, the second sleeve including a lock to fix the second sleeve relative to the second arm; and
a locking element pivotably coupled to a housing of the second arm, the locking element being configured to move between a first orientation in which the second arm is translatable along the longitudinal element and a second orientation in which the second arm is prevented from translating along the longitudinal element.
14. A spinal construct as recited in claim 13 , wherein the longitudinal element is monolithically formed with first arm.
15. A spinal construct as recited in claim 13 , wherein:
the first body includes a pair of resiliently biased latches connectable with a mating element of the first fastener, the latches being biased to a capture position; and
the second body includes a pair of resiliently biased latches connectable with a mating element of the second fastener, the latches of the second body being biased to a capture position.
16. A spinal correction system comprising:
a first spinal construct including fasteners;
a second spinal construct including fasteners;
a surgical instrument including a first arm that is axially translatable relative to a second arm, the arms being connected with and rotatable relative to a longitudinal element;
a first sleeve directly connected with the first arm and engageable with the first spinal construct, the first sleeve being rotatable relative to the first arm in a first orientation and a second orientation, the first sleeve including a lock to fix the first sleeve relative to the first arm, the lock of the first sleeve including a collar and a shaft that support the first arm, the collar defining an opening and the shaft defining an opening, the openings being aligned to support the first arm;
a second sleeve directly connected with the second arm and engageable with the second spinal construct, the second sleeve being rotatable relative to the second arm in a first orientation and a second orientation, the second sleeve including a lock to fix the second sleeve relative to the second arm; and
a locking element pivotably coupled to a housing of the second arm, the locking element being configured to move between a first orientation in which the second arm is translatable along the longitudinal element and a second orientation in which the second arm is prevented from translating along the longitudinal element.
