A set screw for use in association with spinal implant assemblies. The set screw includes a threaded base portion extending along a longitudinal axis and formed of a first material, and a friction member extending from a distal end of the threaded base portion and formed of a second material different from the first material. In one embodiment, the spinal implant assembly includes a connector member having a passage and an opening in communication with the passage, and an elongate support member positioned within the passage of the connector member. The set screw is threadedly engaged to the connector member and at least partially positioned within the opening, with a distal end portion of the friction member extending into the passage and compressed against an outer surface of the elongate support member to inhibit movement of the elongate support member within the passage.

Surgical constructs pre-assembled for insertion as a unit into a patient. The pre-assembled construct may include an elongated member with opposing first and second ends. The construct may also include a connector with a body, a first receptacle that extends through the body and receives the elongated member, a threaded aperture that extends from an exterior of the body into the first receptacle, a fastener threaded into the threaded aperture, and a second receptacle that receives a structural member in the patient. The first receptacle may be larger than the elongated member for the connector to be movable along the elongated member. The construct may also include retaining members permanently attached to each of the first and second ends of the elongated member. The retaining members may include a central opening with an inner radial surface that contacts the elongated member and an outer radial surface that extends outward beyond the elongated member. The retaining members may be larger than the first receptacle to prevent the connector from detaching from the elongated member.
