    摘要： A vertebral rod has an elongated body extending along a longitudinal axis. The rod also includes a cavity extending the length of the body. Either the body or the cavity may have an asymmetrical shape about a centroid in a plane perpendicular to the longitudinal axis. Alternatively, both may have the symmetrical shape about the centroid. The body of the rod may be bounded by an exterior surface and the cavity. The body has a first bending axis that is perpendicular to longitudinal axis. The body also has a second bending axis that is perpendicular to the longitudinal axis and to the first bending axis. The body of the rod may be distributed asymmetrically about the first and second bending axes. Also, the rod may have a different bending stiffness about the first and second bending axes.

    摘要： Elongated connecting elements include bodies having anisotropic cross-sectional shapes defining a first moment of inertia about a first bending axis and a second moment of inertia about a second bending axis that is transverse to the first bending axis. The connecting elements are positioned along one or more spinal motion segments and engaged to vertebrae with anchors with the first and second bending axes in the desired orientation relative to the spinal motion segments.

    摘要： A connector pivotally connects an anchor to a longitudinal member in a spinal implant. The connector body may include an oppositely disposed channel and cavity that are aligned on a common axis of the body, but isolated from each other. The channel receives the longitudinal member and the cavity receives the anchor. The anchor may include a shaft and an enlarged head that fits within the cavity. The cavity may include a narrow opening that is sized to retain the head within the cavity. The head may pivot within a wear member. The anchor may freely pivot within the cavity when a fastener mates with the receiver to maintain the longitudinal member within the channel.

    摘要： A pivoting connector couples a vertebral member to a longitudinal member. An anchor is pivotally attached to a body by positioning a head of the anchor within a cavity in the body. A longitudinal rod is inserted into a channel also positioned within the body and axially aligned with the cavity. A retainer applies a force to maintain the longitudinal rod within the channel, however the force may be isolated from the anchor. The cavity is adjustable between a plurality of sizes that apply different resistances to pivoting movement of the anchor relative to the body. The adjustment may be performed before or during a surgical procedure. The adjustment may be performed by inserting different components or by rotating a threaded element to create more or less rotational interference.

    摘要： The forces exerted on a spinal implant by one or more coupling assemblies are controlled to facilitate the use of the implant in spinal stabilization and other procedures. The coupling assemblies are structured to distribute the forces exerted on the implant while engaging the implant to the coupling assembly and providing at least one of a rigid, semi-rigid or variable engagement of the coupling assembly with one or more anatomical structures of the spinal column.
