Anterior cervical plate fixation. The Sterile Cervical Plate System is named on an EU MDR certificate.
EU MDR
Anterior cervical plating stabilises one to four levels of the cervical spine. The plate lies against the prevertebral soft tissue, so its profile matters. Variable-angle screws are held by a quarter-turn mechanical lock that has no ring to fatigue. The system is supplied with plate screws and larger-diameter revision screws.
The plate is forged from a titanium billet, a process chosen for fatigue resistance and structural density. The aim is high strength at low thickness. The outer rim is rounded, which is intended to make the plate less aggressive against the soft tissue lying over it.
Each plate carries an anatomical radius across the vertebral body and a lordotic radius along the spine. It is designed to sit flush without intraoperative bending. When more or less lordosis is wanted, a plate bender is used. Its channels protect the lock region, because bending at the lock would impair its action.
A central lock covers the two screws of each level. It turns through 90° with the plate screw driver and gives visual and tactile confirmation that it is closed. The mechanism is mechanical, with no ring that can fatigue under high insertion torque, and screws can be unlocked, removed and repositioned in revision. When the lock is closed, the screw heads lie flush or recessed beneath it.
Screws can be angled from −2° to 22° in the cephalad–caudal plane and from −4° to 10° in the medial–lateral plane. A double sleeve prepares both holes at one end of the plate together. An angled sleeve awl reaches the cephalad trajectories without being blocked by the chin or mandible.
Fixation pin holes are positioned to keep the surgical field unobstructed and give a clear line of sight during screw insertion. The plate can be aligned to the endplates under direct sight while it is held with fixation pins. A midline alignment notch helps centring.
The drill has an integrated depth stop that limits drilling depth by contacting the sleeve. The depth is therefore set before drilling instead of being judged during it.
