Spinal rod system and method

1. A spinal rod system comprising:

at least one first instrument extending between a proximal portion and a distal portion along a longitudinal axis thereof, the proximal portion defining an inner cavity extending along the longitudinal axis,

the at least one first instrument including at least one first arm extending along the longitudinal axis, the at least one first arm includes a first leg extension and a second leg extension, the first and second leg extension each including a tapered slot and a distal inner surface having a tapered configuration,

the at least one first arm defining at least a portion of a vertebral construct cavity disposed in communication with the inner cavity and including a distal end being configured to engage a bone fastener;

an actuator arm movable along the longitudinal axis and comprising a distal head that tapers distally to an increased width, the distal head being engageable with the distal inner surfaces to move the at least one first arm in a direction transverse to the longitudinal axis between a first position and a second position such that the distal end of the at least one first arm engages the bone fastener; and

a slide disposed with a slot at a distal end of the actuator arm to fix the slide axially relative to the actuator arm, the slide having enlarged end portions movably disposed in the tapered slots,

wherein the actuator arm comprises an elongated portion including an aperture, the at least one first instrument comprising a pin that is received in the aperture to connect the actuator arm with a handle, the pin extending through inner and outer surfaces of the handle.

2. The spinal rod system of claim 1 , wherein the leg extensions defining an arm cavity therebetween.

3. The spinal rod system of claim 1 , wherein the at least one first instrument further includes an actuator engageable with the at least one first arm to move the at least one first arm between the first position and the second position such that the distal end of the at least one first arm engages the bone fastener.

4. The spinal rod system of claim 1 , wherein the leg extensions define an arm cavity configured for relative movement of the actuator arm therein.

5. The spinal rod system of claim 1 , wherein the first leg extension defines a distal engagement part and the second leg extension defines a distal engagement part, the leg extensions defining an arm cavity configured for relative movement of the actuator arm therein.

6. The spinal rod system of claim 1 , wherein the slide engages a proximal first end of each of the tapered slots when the at least one arm is in the second position to limit movement of the actuator arm.

7. The spinal rod system of claim 1 , wherein the handle includes a grip surface configured to facilitate axial movement of the actuator arm.

8. The spinal rod system of claim 1 , wherein the at least one first arm includes a first arm and a second arm extending along the longitudinal axis, the first arm and the second arm being disposed in opposed relation to define the vertebral construct cavity.

9. The spinal rod system of claim 8 , wherein the at least one first instrument further includes a first actuator engageable with the first arm to move the first arm between a first position and a second position such that the distal end of the first arm engages a bone fastener, and a second actuator engageable with the second arm to move the second arm between a first position and a second position such that the distal end of the first arm engages a bone fastener.

10. The spinal rod system of claim 1 , wherein the slide is removably disposed in a slot of the actuator arm that extends transverse to an axis defined by the actuator arm.

11. The spinal rod system of claim 1 , wherein the vertebral construct cavity is defined by a first wall of the at least one first arm that extends parallel to the longitudinal axis and a second wall of the distal portion that extends transverse to the longitudinal axis.

12. The spinal rod system of claim 1 , wherein the at least one first arm is biased to the second position.

13. The spinal rod system of claim 1 , wherein:

the spinal rod system comprises the bone fastener, the bone fastener comprising first and second extensions each comprising a pair of receiving cavities; and

the first and second leg extensions each include an engagement surface configured to engage the first extension, the engagement surfaces each comprising a tab projecting therefrom, the tabs being spaced apart from the receiving cavities of the first extension when the at least one first arm is in the first position and the tabs being disposed in the receiving cavities of the first extension when the at least one first arm is in the second position.

14. The spinal rod system of claim 13 , wherein the engagement surfaces each include an arcuate surface configured to contour and conform to the first extension to facilitate attachment thereto.

15. A spinal rod system comprising:

at least one first instrument extending between a proximal portion and a distal portion along a longitudinal axis thereof, the proximal portion defining an inner cavity extending along the longitudinal axis,

the at least one first instrument including at least one first arm extending along the longitudinal axis, the at least one first arm includes a first leg extension and a second leg extension, the first and second leg extension each including a tapered slot and a distal inner surface having a tapered configuration,

the at least one first arm defining at least a portion of a vertebral construct cavity disposed in communication with the inner cavity and including a distal end being configured to engage a bone fastener;

an actuator arm movable along the longitudinal axis and comprising a distal head that tapers distally to an increased width, the distal head being engageable with the distal inner surfaces to move the at least one first arm in a direction transverse to the longitudinal axis between a first position and a second position such that the distal end of the at least one first arm engages the bone fastener; and

a slide disposed with a slot at a distal end of the actuator arm to fix the slide axially relative to the actuator arm, the slide having enlarged end portions movably disposed in the tapered slots,

wherein the distal head includes an aperture, the at least one first instrument comprising a pin disposed in the aperture to connect the actuator arm with the first and second leg extensions, wherein the pin engages the slide.
