Abstract
An instrument for guiding a spinal rod into a rod-receiving portion of an implant comprises a linear portion comprising two relatively moveable shafts, an actuator portion coupled to the linear portion for moving the spinal rod relative to the implant and a handle portion for moving the shafts to actuate the actuator portion. The actuator portion holds the rod in place until the surgeon inserts a setscrew or other device for securing the rod to the anchor. The actuator portion further defines a path for inserting and securing a locking device, such as a setscrew, for securing the rod in the implant while also holding the rod in the implant. The path for the screw is aligned with the rod-holding portion of the implant. Using the instrument, a surgeon can guide a rod into a selected position in the implant, reposition the spine to match the contour of the rod, hold the rod in the selected position and secure the rod to the implant.
