摘要：
Various methods and devices are provided for bone screw fixation. In one exemplary embodiment, the methods and devices provide a bone fixation device that includes a receiving head having a recess adapted to seat a spinal rod therein and a shank extending distally from the receiving head. An anti-rotation mechanism can be located distal of a distal end of the receiving head and around a proximal portion of the shank, and it can be configured to interact with bone to prevent rotation of at least a portion of the bone fixation device relative to the bone.
