InViZia™ Anterior Cervical Plate System

Product Description

This innovative cervical plate system is designed for anterior interbody screw fixation of the cervical spine. The inVIZia System features direct visualization of implant placement and screw locking for ease of use. With its generous graft window, low profile, simple locking mechanism, narrow waist, and aggressive self-drilling screws, it is a complete solution in one user-friendly spinal implant.


  • Large graft window provides clear endplate visualization
  • Low-profile (less than 2mm) plate
  • Secure-Twist ® Locking Mechanism provides visual and tactile confirmation of locking mechanism engagement
  • Aggressive self-drilling screws

Device Description

The inViZia Anterior Cervical Plate System consists of:

  • Cervical plates
  • Locking caps
  • Fixed and Variable Angle Bone Screws (these are the same bone screws used in the Trinica ® Anterior Cervical Plate System)
  • Instrumentation necessary for implantation of the system

All implant components are made from titanium alloy (Ti-6Al-4V). The inViZia Anterior Cervical Plate System is intended to provide stabilization of the cervical vertebrae for the indications below. The fixation construct consists of a cervical plate that is attached to the vertebral body of the cervical spine with self-tapping and self-drilling bone screws using an anterior approach. Bone screws are available for fixed angle or variable angle implantation. These are the same screws used in the Trinica Anterior Cervical Plate System. The inViZia Anterior Cervical Plate System is intended to be removed after solid fusion has occurred.

Refer to the Surgical Technique Manual for additional information on how to use this device. Contact your Zimmer Spine Sales Representative for a copy of the current Surgical Technique.


The inViZia™ Anterior Cervical Plate System is designed for anterior interbody screw fixation of the cervical spine at levels C2-T1. The inViZia Anterior Cervical Plate System is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), trauma (including fractures), tumors, deformity (defined as kyphosis, lordosis or scoliosis), pseudoarthrosis and/or failed previous fusions.

WARNING: This device is not approved for screw attachment to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.


Contraindications for use of the inViZia Anterior Cervical Plate System include:

  • Overt infection or distant foci of infections
  • Local inflammation, with or without fever or leukocytosis
  • Pregnancy
  • Diseases or conditions other than those specifically described in the Indications section
  • Use in the posterior elements (pedicles) of the cervical, thoracic, or lumbar vertebrae
  • Where attempted correction exceeds the limits of physiological conditions
  • Uncooperative patient or patient with neurologic disorders rendering the patient incapable of following instructions
  • Metabolic disorders that may impair bone formation
  • Inadequate bone stock to support the device
  • Inability to restrict high activity level
  • Obesity
  • Poor prognosis for good wound healing (e.g., decubitis ulcer, end-stage diabetes, severe protein deficiency and/or malnutrition)


Some metals, polymers, chemicals, and other materials utilized with orthopedic implants have been known to cause cancer and other adverse body reactions, or reports in the literature have suggested such causation. Any factor that causes chronic damage to tissues may be oncogenic. Cancer can metastasize from soft tissue sites (lung, breast, digestive system, and others) to bone, including areas adjacent to implants, or it can be seeded to these locations during operative and diagnostic procedures (such as biopsies). Paget’s disease has been reported to progress to cancer; surgical candidates suffering from this disease should be warned accordingly.

Implantation foreign material in tissues can elicit an inflammatory reaction. Current literature suggests that wear debris (including metal, polyethylene, ceramic, and cement particles) can initiate the process of histiocytic granuloma formation and consequent osteolysis and loosening.

Metal sensitivity has been reported following exposure to orthopedic implants. The most common metallic sensitivities (nickel, cobalt, and chromium) are present in medical grade stainless steel and cobalt-chrome alloys.

The inViZia Anterior Cervical Plate System is a temporary internal fixation device. Internal fixation devices are designed to stabilize the operative site during the normal healing process. After healing occurs, these devices serve no functional purpose and must be removed. Implant removal should be followed by adequate postoperative management to avoid fracture or refracture.


The inViZia Anterior Cervical Plate System instrumentation should only be used after the surgeon has had adequate training in this method of fixation and has become thoroughly knowledgeable about the spinal anatomy and biomechanics. A surgical technique for the inViZia Anterior Cervical Plate System is available upon request. This technique is not a substitute for training and is for general informational purposes only.

The inViZia System uses Trinica System bone screws. Components from other anterior cervical plating systems, however, should not be used with the inViZia System because compatibility has not been established.

Do not use implants made from dissimilar metals (such as cobalt chromium-molybdenum alloy or stainless steel) in contact with components of the inViZia Anterior Cervical Plate System; otherwise, galvanic corrosion may occur.

If contouring of the implant is necessary for optimal fit, the contouring should be gradual and avoid any notching or scratching of the implant(s) surface. The plates must not be repeatedly or excessively bent. Do not reverse bend the plate.

All implants and some instruments are intended for single use only; refer to the product label to determine if the instrument is intended for single use only. Single use devices should not be re-used. Possible risks associated with re-use of single use devices include:

  • Mechanical malfunction
  • Transmission of infectious agents

Adverse Effects

Complications and adverse reactions have been reported with the use of similar spinal instrumentation systems. These adverse effects, including the possibility of death, should be discussed with the patient prior to surgery.

Possible neurologic operative/postoperative adverse reactions that may require medical or surgical intervention(e.g., implant removal with or without re-instrumentation) include:

  • Paralysis, complete or incomplete. Delayed onset has occurred even when evoked potential was unaffected during surgery
  • Dural tear leading to cerebrospinal fluid fistula or pseudo meningocele
  • Other spinal cord injuries not otherwise described due to positioning of the spinal attachment device
  • Laminar erosion
  • Epidural bleeding
  • Abnormal sensations
  • Radiculopathy

Possible device postoperative complications/adverse reactions that may require medical or surgical intervention(e.g., implant removal with or without re-instrumentation) include:

  • Loosening, bending, b
