A titanium posterior spinal fixation system for occipitocervical, upper cervical and lower cervical stabilization applications.
Titanium
3.5mm fixed rod
Screw-rod posterior fixation
The system is presented with multiple occipital fixation methods, a low-profile 3.5mm rod design, optional instruments for different clinical habits, and a polyaxial screw structure for flexible construct adjustment.
Different occipital fixation methods can be selected according to surgeon preference and case requirements.
The system uses a 3.5mm diameter fixed rod with a lower-profile posterior fixation construct.
Optional tools are available to support different clinical habits and surgical workflow preferences.
The low-profile design helps reduce stimulation of the surrounding soft tissue around the construct.
The negative-angle thread design helps prevent the screw arm from expanding.
The special-structure polyaxial screw design supports maximum unidirectional motion up to 55°.
The procedure content is arranged as visual cards so it reads better online than the original PDF spread. Keep the professional-use notice above this section when publishing.
The patient is placed in a prone position as for a standard midline posterior cervical incision. Expose the occipital bone, posterior arch of the atlas, and the articular mass and arch of the cervical segment that need to be fused.
After determining the entry point and entry angle, the cortical bone is drilled with an open drill and the hole is enlarged.
The screw entry point is described as inward to the middle point of the side mass and 2mm upward. The entry angle is tilted outward 20°-25° and toward the head end 30°-40°, parallel to the adjacent articular surface.
Proper placement of lower cervical C3-C7 screws helps minimize vertebral artery and nerve risk while providing maximum screw length and optimal fixation.
Lower cervical C3-C7: the screw entry point is 2-5mm inside the outer edge of the side block and 2-3mm below the base of the articular surface of the upper facet. The entry angle is 30°-45° inside the coronal plane, with the sagittal plane parallel to the upper endplate.
Upper cervical C1-C2: C1 lateral mass screw entry is described around 18-20mm beside the midpoint of the posterior tubercle of the atlas, with depth controlled at about 28mm. C2 pedicle screw entry is described at the midpoint of the vertical line in the middle of the lateral mass, with depth generally about 24-26mm.
These screw entry descriptions are professional reference content from the IFU and depend on the specific surgical situation.
Use the drill bit and guide to drill and determine the depth to be drilled. Adjust the guide to the corresponding scale to limit the depth.
Control drilling speed and depth strictly according to measured data. Stop drilling immediately once reaching the predetermined depth to avoid over-penetration of vertebral cortex and damage to peripheral nerve or vascular tissue.
Remove the drill bit after the hole is finished and clean bone debris inside the pilot hole.
The depth of the screw path is measured with the depth gauge and screws of appropriate length are selected.
If the bone is hard, tapping can be used.
This section converts the implant insertion pages into a clear web layout with separated procedural cards and related images.
Use the screwdriver to implant screws. Insert the hexagon of the screwdriver into the screw completely, then screw into the locking sleeve to implant the screw.
Use screw-holding forceps to assist in screw insertion and positioning. Sequentially insert the remaining screws following the identical procedural template.
Select the appropriate rod length according to the anatomical curvature of the patient. The rod is cut and prebent according to the rod movement to accommodate the sagittal curve of the spine.
Excessive and repeated bending should be avoided to maintain material integrity. The rod should be carefully checked for damage before implantation.
Hold the rod with the rod-holding forceps and place it into the U-shaped slots of the implanted screws.
Using the preload wrench, insert the screw plug into the U-shaped threaded slot. Initially tighten one set screw with the hexagonal wrench to secure the rod provisionally.
After the spinal rod is seated into the U-shaped slots of the pedicle screws, reduction and contouring maneuvers can be performed.
Compression: mount compression forceps on adjacent pedicle screws and apply inward closing force to draw two vertebrae closer via rod linkage.
Distraction: install distractor between two adjacent screws and distract along the rod to recover lost intervertebral height and release compressed nerve roots.
Rotation: grip the rod with rod rotators and rotate the spinal rod inside the screw U-slot to adjust sagittal curvature and align screw openings.
Using the anti-rotation sleeve, insert the screw plug into the U-shaped slot of the screw and provisionally tighten it with the hexagonal wrench.
Lock all occipital and cervical screws from top to bottom, and implant transverse connectors as required.
After confirming the desired alignment and implant position, perform final tightening of all set screws using the specified torque-limiting wrench.
Verify that all components are securely locked and the construct is stable before wound closure.
Note: the torque-limiting wrench is an optional accessory and is sold separately.
Confirm alignment, implant position, component locking and construct stability before closure.
