Advance Information*

Introduction

The Anterior Cervical Plate System Spine Implants are advanced medical devices that are meticulously designed to provide optimal stabilization and support during anterior cervical discectomy and fusion (ACDF) procedures. Among these innovative implants, the C-fix Cervical Interbody Anterior Cage stands out due to its unique features. This comprehensive description delves into the specific aspects of the C-fix system, elucidating its design, functionality, technical specifications, materials, and much more.

Overview of Anterior Cervical Discectomy and Fusion (ACDF)

What is ACDF?

Anterior Cervical Discectomy and Fusion (ACDF) is a surgical procedure aimed at alleviating symptoms caused by nerve root or spinal cord compression. This compression may emerge from a variety of conditions, such as herniated discs, degenerative disc disease, or trauma. The procedure involves removing the problematic disc and stabilizing the vertebrae using an implant.

The C-fix Cervical Interbody Anterior Cage

Integrated Design

The C-fix system is pioneering in its approach, offering a cervical interbody anterior cage with integrated internal screw fixation. This innovative design merges the functionality of traditional cages and anterior plates into a singular, cohesive unit.

• Rigid Screw Fixation: The screws are designed to anchor securely into the vertebrae, providing stability without the need for an additional anterior plate.
• Ultra-low Profile: The cage is designed to be minimally invasive, with an ultra-low profile that avoids protrusion from the anterior surface, reducing the potential for soft tissue irritation.

Indications for Use

The C-fix cage is intended for patients undergoing cervical discectomy and fusion, specifically those requiring rigid spinal support to address cervical spine instability.

5. Reduces risk of soft tissue damage.

6. Ensures minimal interference with anatomical structures.

7. Biomechanical Rigidity:

8. Provides strong and stable support.

9. Promotes successful bony fusion.

10. Variety of Sizes:

11. Available in multiple dimensions to suit different patient anatomies and clinical situations.

12. Material Composition:

13. Constructed from biocompatible materials, ensuring safety and reducing the risk of adverse reactions.

Technical Specifications

Dimensions and Variants

• Height Options:

• Available in heights ranging from 5mm to 11mm to accommodate varying levels of disc space collapse.

• Footprint (AP x ML):

• Several footprints available to fit diverse vertebral morphologies adequately.

• Screw Length and Diameter:

• Screws come in varied lengths and diameters to ensure secure fixation.

Radiographic Visibility

• Radiopaque Markers:
• Equipped with radiopaque markers to enhance visibility under fluoroscopy, aiding in accurate placement and postoperative assessment.

Materials

Cage

• Titanium Alloy (Ti-6Al-4V):
• Known for its superior strength-to-weight ratio.

• Excellent biocompatibility, promoting osseointegration.

• PEEK (Polyetheretherketone):

• Sometimes used for its modulus of elasticity similar to bone.
• Radiolucent properties allow easy postoperative imaging.

Screws

• Titanium Alloy:
• Durable and strong, ensuring long-term fixation and stability.

Surface Coating

• Hydroxyapatite Coating:
• Optional coating promotes bone in-growth and faster fusion rates.

Design Features

Optimized for Easy Insertion

• Tapered Leading Edge:

• Facilitates easier insertion and reduces the risk of endplate damage.

• Teeth Pattern:

• Incorporated teeth pattern on the superior and inferior surfaces increases stability and minimizes the risk of implant migration.

Anatomical Contouring

• Curved Profile:
• Matches the natural curvature of the cervical spine, providing an anatomically correct fit.

Surgical Procedure

Preoperative Planning

• Patient Assessment:
• Detailed imaging studies (MRI, CT) to ascertain exact pathology and plan implant placement.

Surgical Technique

1. Incision and Exposure:

2. A small incision on the anterior neck to access the cervical spine.

3. Disc Removal:

4. Careful removal of the affected disc along with any osteophytes or pathological tissue.

5. Preparation of Endplates:

6. Ensure the vertebral endplates are prepared for optimal seating of the C-fix cage.

7. Cage Insertion:

8. The C-fix cage is inserted into the
