Abstract
A bone screw assembly comprises a bone screw having a shaft and a head, a stabilizer retainer, a set screw, and a housing having a proximal opening, biased to one side, and a distal opening that open on an interior cavity. 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 bone screw, the stabilizer retainer and the set screw in the interior cavity. The housing has a channel that permits passage of the stabilizer though the housing. The set screw is engaged in the distal opening. The set screw and stabilizer retainer engage and prevent movement of the flexible portions, preventing movement of the stabilizer from the stabilizer retainer.
