摘要： Instruments and methods are provided for manipulating a bone anchor and a spinal fixation element. The instruments and methods disclosed herein are particularly suited to facilitate rotation of a bone anchor relative to another bone to correct the angular rotation of the vertebrae attached to the bone anchor. The instrument does not require the spinal fixation element to be inserted into the bone anchor prior to manipulation. The instrument further may be used in the insertion of the spinal fixation element into the bone anchor.

摘要： 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.

摘要： Methods and devices are provided for reducing a spinal fixation element into a spinal implant element. In one exemplary embodiment, a spinal rod reduction device is provided for reducing a spinal fixation element into a spinal implant element. The spinal rod reduction device can include a fastener engaging member for engaging at least a portion a spinal implant element, a reduction member for engaging at least a portion of a spinal fixation element, and a handle assembly mated to the reduction member. The handle assembly can be designed in such a way that actuation of the handle assembly causes movement of the reduction member relative to the fastener engaging member and the movement of the reduction member reduces the spinal fixation element into the spinal implant element. Two different styles of spinal rod reduction devices are discussed in detail. Various techniques are also provided for reducing a spinal fixation element into a spinal implant element.

摘要： An instrument for manipulating a spinal fixation element relative to a bone anchor includes a bone anchor grasping mechanism, a first adjustment mechanism, and a second adjustment mechanism. The bone anchor grasping mechanism includes a first arm having a distal end configured to engage an opening provided in the bone anchor. The first adjustment mechanism includes a second arm pivotally connected to the first arm. The second arm has a distal end configured to engage an opening provided in the bone anchor and is operable to adjust a spinal fixation element in a first direction upon pivoting relative to the first arm. The second adjustment mechanism is removably and replaceably coupled to the bone anchor grasping mechanism and is movable relative to the bone anchor grasping mechanism to adjust the spinal fixation element in a second direction, perpendicular to the first direction, relative to the bone anchor.

摘要： The present invention provides methods and devices for reducing a rod disposed within or adjacent to a rod-receiving head of a spinal implant. In general, a rod reduction device is provided that can removably mate to the rod-receiving head of a spinal implant and be effective to reduce a rod disposed within or adjacent to the rod-receiving head. In an exemplary embodiment, the rod reduction device can include a clamping member that is adapted to removably mate to a rod-receiving head of a spinal implant and a rod-reducing arm that is rotatably matable to the clamping member. The rod-reducing arm can be configured such that rotation of the arm with respect to the clamping member is effective to reduce a rod into the rod-receiving head of the spinal implant that is mated to the clamping member.
