Abstract
The present invention addresses rod rotation and slippage inside the tulip rod channel(s), as well as forcible rod bending as the spine and musculature bias towards a deformity, for example. The present invention provides a stabilization rod that, fundamentally, includes at least one flat surface on at least one side of the construct, this flat surface engaging a corresponding flat surface associated with the head body, set screw, or locking cap. Multiple flat surfaces may, of course, be used. The stabilization rod may also include one or more ridges and/or one or more keyed channels that is/are engaged by the head body, set screw, or locking cap.
Claims21
A stabilization rod for coupling a plurality of bone anchors together, the stabilization rod comprising:
- an elongate body;
- wherein the elongate body comprises at least one flat surface;
- and
- wherein the at least one flat surface is configured and positioned to engage at least one corresponding flat surface associated with one or more of a head body assembly, a set screw, and a locking cap of the bone anchor such that relative rotation of the elongate body and the bone anchor is prevented.
A method for providing a stabilization rod for coupling a plurality of bone anchors together, the method comprising:
- providing an elongate body;
- wherein the elongate body comprises at least one flat surface;
- and
- wherein the at least one flat surface is configured and positioned to engage at least one corresponding flat surface associated with one or more of a head body assembly, a set screw, and a locking cap of the bone anchor such that relative rotation of the elongate body and the bone anchor is prevented;
- and
- disposing the elongate body in the head body.
A bone anchor, comprising:
- a threaded screw portion;
- a head body coupled to the threaded screw portion;
- and
- an elongate body coupled to the head body;
- wherein the elongate body comprises at least one flat surface;
- and
- wherein the at least one flat surface is configured and positioned to engage at least one corresponding flat surface associated with one or more of the head body assembly, a set screw, and a locking cap of the bone anchor such that relative rotation of the elongate body and the head body is prevented.
