A system of devices and methods for use by which one or more target motion segments of the cervical spine are stabilized without any violation of the cortical bone of the target vertebrae. The devices are brought against strategic aspects of these vertebrae, thus permitting the disclosed inventions to achieve secure control of each vertebra. Connecting elements then stabilize the constructs. Preferred and alternative embodiments of the invention are disclosed, along with methods of implantation, and adjunct devices used in the implantation of the disclosed invention.

A pivotal bone anchor assembly includes a shank having a head portion and an anchor portion for fixation to the bone of a patient, and a receiver comprising a base defining a lower portion of central bore and a pair of upright arms defining a channel for receiving an elongate rod. The assembly also includes a retaining structure with a central opening configured to capture and pivotally retain and support the head portion of the shank in the retaining structure, and which is slidably movable relative to the receiver so as to provide for increased articulated movement between the shank and the receiver prior to locking the assembly with the elongate rod and a closure. The assembly further includes an insert configured to engage the elongate rod and the head portion of the shank when in use, and to have an overlapping configuration with the retaining structure when the assembly is in the locked configuration.

Connector assemblies, systems, and methods thereof. A modular connector has a first end that clamps to a first rod in an existing construct and a second end having a modular connection point configured to connect a second rod in a new construct such that the new construct can be extended from the existing construct.

The present invention discloses fusion systems and methods of assembly and use. The fusion systems include a first fastener, a second fastener, and an elongate member with a first end and a second end. The first end being secured to the first fastener and the second end being secure to the second fastener. The method of assembling a fusion system and methods of using the fusion systems are also disclosed.

A connection device for connecting an end region of an already implanted first spinal column support, at which pedicle screws are coupled on their head side to a first connection rod by respective coupling devices, to an already or not yet implanted spinal column support portion having a pedicle screw and extending the first spinal column support, having a first fastening arrangement for fastening the connection device to the first connection rod and a coupling for the extending support portion, in particular a second rod to be coupled to the pedicle screw of the extending support portion or a second fastening arrangement for fastening the connection device to such a second rod, further having a rigid bridge, laterally clinging to the coupling device of the closest pedicle screw of the first spinal column support on the connection side, of an intermediate region between the first fastening arrangement and the coupling.

A personalized fixation system includes a surgical planning software tool configured to adjust relationships of relevant anatomy of a subject, at least one bone anchor, a plate having a shape that does not conform to a single plane, the plate configured to accept the at least one bone anchor, wherein the shape of the plate is at least partially determined by the surgical planning software tool, and wherein the plate includes at least one node having a hole configured to receive the at least one bone anchor, and a locking element configured to connect the at least one bone anchor to the plate, wherein the plate is manufactured using additive manufacturing.

Methods and devices for the tailored restraint of two separate bones, in which the bones are generally permitted to rotate relative to one another, or move toward each other, but are restrained from separating beyond a predetermined, fixed distance. In some embodiments, the restraint is provided by compressing a tether into a notched groove.
