A bone screw apparatus, system, and method for assisting in the placement and alignment of a bone screw and for aligning bone are described. The present invention allows a surgeon to position a bone screw in a desired position and adjust a coupling element in a variety of positions and angles with respect to the bone screw.

Bone screw apparatus, system and method

An intervertebral stabilizer includes: a first plate member operable to engage an endplate of a first vertebral bone of a spine; a second plate member spaced apart from the first plate member and operable to engage an endplate of an adjacent second vertebral bone of the spine; a ball element depending from the first plate member; and a socket element depending from the second plate member, wherein at least one of the ball and socket elements include one or more keyed surfaces such that: (i) an assembly function is obtained in which the ball element may at least one of be received into, and removed from, the socket element in one or more first articulation positions of the first and second plate members; and (ii) a capture function is obtained in which the ball element may at least one of not be received into, and not be removed from, the socket element in one or more second articulation positions of the first and second plate members.

A stabilization system for implantation in a patient includes: at least first and second bone anchors, each bone anchor including a shaft extending in a respective bone insertion direction for connection to a respective bone of a patient, and a fastening member; and an elongate member comprising a first end portion, a first transverse portion extending transversely from the first end portion, a second end portion, a second transverse portion extending transversely from the second end portion, and a connecting portion extending in a longitudinal direction between the first and second transverse portions.

Method and apparatus for bone stabilization

A stabilization rod engaging apparatus for implantation in a patient includes: a first pivot element including at least one first aperture, a first engagement element, and a first locking element; a second pivot element including at least one second aperture, a second engagement element, and a second locking element, wherein: the first and second apertures are sized, shaped and disposed in substantial axial alignment such that they are operable to receive the stabilization rod therethrough, and displacement of the first and second locking elements relative to one another urges the first and second apertures to misalign and thereby clamp the stabilization rod.
