A coupling assembly that is configured to couple a surgical screw to another coupling assembly and another surgical screw is disclosed. The coupling assembly comprises a body that includes a receptacle configured to receive a head portion of the surgical screw and hold the head portion through an interference fit. The body further includes either a female member, a male member, or both, the female member and the male member configured to mate with a female member and a male member of the another coupling assembly and thereby join the coupling assembly to the another coupling assembly. Embodiments of the coupling assembly provide for adjustment of the distance between the coupling assemblies, as well as misalignment of various axes of the coupling assembly relative to the surgical screw and the male member. Exemplary embodiments provide fewer parts, greater flexibility during the surgical implantation, and a smaller profile than previous coupling mechanisms. |
