Patent ID: 8057523

Claim:
A set screw for use with a receiver to secure an elongated member within a patient, the set screw comprising: a body with a first end and second end; a sidewall that extends outward from and around a periphery of the second end and forms a recess with the second end; an extension that extends outward from the second end, the extension including a base at the second end and a tip at a distal end that faces outward from the body, the extension extending between the base and the tip being straight and coaxial with a centerline of the body; an annular member positioned within the recess and extending around the extension, the annular member being attached to the body to prevent rotation of the annular member relative to the body; the sidewall, extension and annular member each positioned to space the body away from the elongated member with each positioned to contact against the elongated member when the set screw is engaged with the receiver; the annular member constructed from a more deformable material than either the set screw and the receiver to deform against the elongated member.
