A bone screw assembly comprises a bone screw, a stabilizer retainer, a set screw, and a housing. The housing may have a proximal opening, biased to one side, and a distal opening that open on an interior cavity or the housing may be part of the bone screw. The stabilizer retainer has a cylindrical channel that receives a stabilizer. The retainer has flexible portions that allow passage of the stabilizer into the channel. An arcuate wall of the channel maintains contact with the stabilizer within the channel. The housing is adapted to receive the stabilizer retainer and the set screw in the interior cavity. The housing has a channel that permits passage of the stabilizer through the housing. The set screw is engaged in the distal opening to engage and prevent movement of the flexible portions, preventing movement of the stabilizer from the stabilizer retainer. |
