An adjustable articulating spinal rod system including a first elongated element secured to a first bone, a second elongated element secured to the spine, and an articulating joint connecting the first and second elongated elements. The articulating joint including a first movable joint, a second movable joint, and at least one locking mechanism. The first movable joint is coupled to the first elongated element and the second movable joint which is also coupled the second elongate element. The first and second movable joints are configured to allow polyaxial movement and rotation of the first elongated element with respect to the second elongated element. The at least one locking mechanism immobilizes the first and second movable joints in the locked position to secure the first elongate element in a position relative to the second elongate element and allow movement and rotation in an unlocked position.

This disclosure describes a variety of transitional or terminal components that may be implanted as part of a spinal fixation construct to decrease the potential for subsequent development of junctional disease. The fixation construct may extend any number of levels from a single level construct to a long construct spanning multiple spinal levels and multiple spinal regions from the lumbosacral to cervical regions, and with any variety of combination of anchors, rods, and connectors. Terminal and/or transitional components may be utilized at the caudal and or cephalad ends of the fixation construct to reduce stresses endured by the construct adjacent pathology and prevent or reduce incidence and degree of junctional disease.

Lamina plate assemblies, systems, and methods thereof. A lamina plate assembly may be configured to provide lamina support following laminectomy, for example, in cervical and lumbar cases. The lamina plate assembly may include a generally elongate body having a first free end, a second free end, and a posterior portion disposed between the first free end and the second free end. Different embodiments of securing portions are used to secure the lamina plate assembly to a vertebra.

A spinal fixation device is provided having first and second elongate members that are angularly adjustable relative to one another. Each elongate member can include a connecting feature formed on a terminal end thereof, and each connecting feature can be coupled to one another to allow angular movement of the first and second elongate members. The device can also include a locking mechanism that is adapted to couple to the connecting feature on each of the first and second elongate members to lock the elongate members in a fixed position relative to one another.

An articulating assembly includes a first elongated element for attachment to a first anatomical region, and a second elongated element for attachment to a second anatomical region. In at least one embodiment, a coupling connects the first and second elongated elements. The coupling includes a moveable joint configured to allow polyaxial movement of the first elongated element with respect to the second elongated element. The assembly further includes a locking mechanism. The locking mechanism is operable in an unlocked condition to permit polyaxial movement of the first elongated element with respect to the second elongated element, and a locked condition to immobilize the movable joint and fix the position of the first elongated element with respect to the second elongated element.

A segmented rod assembly for aligning a spine including a plurality of vertebrae, including a rod, including a plurality of segments, the plurality of segments having at least a first segment arranged to be connected to a first vertebra of the spine, the first segment including a first body and at least one tang extending from the first body, and a second segment arranged to be connected to a second vertebra of the spine, the second segment including a second body and at least one channel arranged in the second body, wherein the at least tang is operatively arranged to engage the at least one channel, and at least one tensioning member arranged within the plurality of segments, the at least one tensioning member having a first end secured to the first segment and a second end.

A jointed rod assembly for use in a spinal fixation construct involves a caudal rod portion connectable to an adjustment mechanism, and a cranial rod portion connectable to the adjustment mechanism. The adjustment mechanism is configured to rotate the caudal and cranial rod portions relative to one another about a joint axis that is generally perpendicular to the longitudinal axes of the caudal and cranial rod portions. The caudal and cranial rod portions may be dimensioned to be compatible with other pieces of hardware commonly used for spinal fixation, such as bone anchors (e.g., pedicle screws), occipital plates, reducers, and others. The caudal and cranial rod portions are composed of a strong, rigid, non-absorbable, biocompatible material. The jointed rod assembly may be advantageously used in spinal fixation systems and methods of spinal fixation.

Lamina plate assemblies, systems, and methods thereof. A lamina plate assembly may be configured to provide lamina support following laminectomy, for example, in cervical and lumbar cases. The lamina plate assembly may include a generally elongate body having a first free end, a second free end, and a posterior portion disposed between the first free end and the second free end. Different embodiments of securing portions are used to secure the lamina plate assembly to a vertebra.

An adjustable articulating spinal rod system including a first elongated element secured to a first bone, a second elongated element secured to the spine, and an articulating joint connecting the first and second elongated elements. The articulating joint including a first movable joint, a second movable joint, and at least one locking mechanism. The first movable joint is coupled to the first elongated element and the second movable joint which is also coupled the second elongate element. The first and second movable joints are configured to allow polyaxial movement and rotation of the first elongated element with respect to the second elongated element. The at least one locking mechanism immobilizes the first and second movable joints in the locked position to secure the first elongate element in a position relative to the second elongate element and allow movement and rotation in an unlocked position.

A segmented rod assembly for aligning a spine having a plurality of vertebrae, including a rod, including a plurality of segments, the plurality of segments having at least a first segment arranged to be slidingly secured to a first vertebra of the spine, a second segment arranged to be fixedly secured to a second vertebra of the spine, and a third segment arranged between the first and second segments to be connected to a third vertebra of the spine, a tensioning member arranged within the plurality of segments, the tensioning member having a first end secured to the first segment and a second end.
