DEVICE: Zavation (00842166195004)

A small, threaded, implantable rod with a screw head and drive intended for internal spinal fixation by being screwed into the spine to hold a correction/stabilization device (e.g., rod, plate, tether) to bone; it is made of a material that is not chemically degraded or absorbed via natural body processes (e.g., surgical steel, titanium alloy, carbon fibre). It is available in various types (e.g., pedicle or transfacet, with a slotted, cross, star, or polygonal drive), and is typically used to provide immobilization and stabilization of spinal segments in the treatment of spinal instabilities or deformities. A screw head adaptor intended to stabilize a rod may be included with the screw.

A small, implantable, non-customized sheet of solid material intended to be attached to the spine with screws for spinal immobilization; it is made of a material that is not chemically degraded or absorbed via natural body processes (includes implant grade metal such as surgical steel, titanium alloy, or carbon fibre). The device is typically used to provide immobilization and stabilization of spinal segments in the treatment of various spinal instabilities or deformities (e.g., during anterior/posterior cervical, anterior/posterior lumbar, thoracolumbar, and occipital fixation procedures).
