  • Distal loading receiver for a polyaxial bone screw and method for implantation thereof
    Patent number: 8974501
    Abstract: A distal loading receiver for a polyaxial bone screw includes a body member having a circumferential wall defining a bore disposed longitudinally through the body member. A skirt depends from a distal end of the body member. The skirt defines one or more distally opening slots and an abluminal surface of the skirt includes one or more transverse ribs proximate to a distal end of the skirt. A retaining ring includes a luminal surface having one or more transverse recesses proximate to a distal end of the luminal surface and one or more walls extending inwardly from the luminal surface. The slots accommodate the walls and the recesses accommodate the ribs to attach the body member to the retaining ring when the distal end of the skirt is inserted into a proximal end of the retaining ring.
