A method for manipulating a vertebra includes connecting a first bone anchor to a first vertebra, connecting a second bone anchor to a second bone anchor, positioning a spinal rod in a receiving member of the first bone anchor and in a receiving member of the second bone anchor, connecting a first instrument to the receiving member of the first bone anchor, and manipulating the first instrument to rotate first bone anchor and the first vertebra relative to the second vertebra.

Instruments and methods for manipulating a vertebra

An instrument for inserting, adjusting and engaging an implant, such as a polyaxial screw of a spinal fixation system, includes at least one retratractable tab for engaging a corresponding recess on the implant and a shaft that moves relative to the retractable tab. The movable shaft selectively moves the tab between an expanded position for engaging the recess and a retracted position out of engagement with the recess. The shaft selectively engages a portion of the implant to rigidify the implant after the retractable tab engages the recess. The axially extending shaft may be disposed within an axially extending passageway of a body assembly. A rotatable collar surrounding the body assembly is coupled to the shaft for moving the shaft relative to the retractable tab.

A rod reduction device is provided having a reduction nut adapted to mate to the rod-receiving portion of a spinal implant, and a driver tool that is effective to engage the reduction nut such that rotation of the driver tool rotates the reduction nut to reduce a rod positioned between the reduction nut and within the rod-receiving head of a spinal implant into the rod-seating portion of the head of the spinal implant. The driver tool can include a supportformed on a distal end thereof that is adapted to be disposed within the rod-receiving head of a spinal implant to prevent the rod-receiving head of the implant from collapsing during use of the rod reduction device.
