Cervical PEEK Cage (4 Locking Screws)

Engineered from radiolucent PEEK (ASTM F2026) with embedded locking screws, the cervical PEEK cage offers a zero-profile solution with biomechanically robust fixation through four angled screws. It restores disc height and lordosis without requiring anterior plate hardware, reducing dysphagia risk and facilitating clearer imaging follow-up. CEmarked and ISO13485/9001 certified, it supports single to twolevel cervical fusion procedures with immediate fixation and simplified surgical workflow.

Product Description

Cervical PEEK Cage (4 Locking Screws) Overview


Cervical PEEK Cage (4 Locking Screws) Features and Benefits

Four integrated locking screws provide immediate, multi-axial anchorage

Zero-profile design minimizes anterior hardware prominence

PEEK core offers bone-like elasticity to reduce subsidence

Radiolucent material allows clear imaging without artifact

Generous graft chamber for bone substitute/fusion material

Titanium or Ti‑6Al‑4V screws—self-tapping and locking

Variable screw trajectories for better purchase in vertebral bodies

Easier, faster implantation relative to plate-plus-cage systems



Cervical PEEK Cage (4 Locking Screws) Indications

Single- and two-level ACDF (C3–C7) in skeletally mature adults

Cervical degenerative disc disease, radiculopathy, or myelopathy

Early cervical fusion without anterior plating to reduce soft tissue complications

Revision cases where previous plate placement complicates hardware removal

Situations where cervical lordosis correction and subsidence resistance are priorities

Cervical PEEK Cage (4 Locking Screws) Insights



What is the Cervical PEEK Cage (4 Locking Screws)?


This is a stand-alone cervical fusion implant designed for anterior cervical discectomy and fusion, combining a PEEK spacer with four self-tapping, locking titanium screws. It offers immediate mechanical stability—comparable to plating—but without external anterior hardware.


Applications of Cervical PEEK Cage (4 Locking Screws)

The Cervical PEEK Cage (4 Locking Screws) is indicated for use in:

Supports anatomical alignment and segmental stability in one‑ or two‑level ACDF

Ideal for patients at higher risk of dysphagia from anterior plates

Useful in revision surgeries involving prior hardware

Targets clinical scenarios with risks of subsidence or cervical instability

Enhances multi-screw fixation in osteoporotic or compromised vertebral bodies



Advantages of Cervical PEEK Cage (4 Locking Screws)

Multi-screw fixation minimizes micro-motion and migration

Eliminates need for anterior plate—simplifies surgical approach and reduces complications

PEEK’s elasticity aligns with endplate mechanics, lowering subsidence risk

Clear postoperative visualization of fusion progression without CT/MRI artifact

Faster instrumentation and reduced implant footprint streamline workflow



Biomechanics of Cervical PEEK Cage (4 Locking Screws)


Meta-analyses and recent comparative studies show self-locking stand-alone cages have lower dysphagia and adjacent-segment degeneration (ASD) than plate-augmented constructs, particularly in multilevel cases. Fusion rates between the two approaches are clinically similar, though plate systems may better preserve segmental lordosis and reduce subsidence in three‑level fusions. Clinical evidence supports self-locking cages with four-screw designs offering comparable biomechanical stability in one- or two-level fusions.


Surgical Technique of Cervical PEEK Cage (4 Locking Screws)

Expose disc space via standard anterior cervical approach

Perform discectomy and endplate preparation

Select cage size and lordotic angle via preoperative imaging

Load cages with bone graft or substitute

Insert cage into disc space with snug fit

Advance all four screws per pre-angled trajectories into adjacent vertebral bodies

Confirm seating and alignment under fluoroscopy

Avoid over-distraction of disc space; follow torque guidelines for screw locking



Postoperative Care of Cervical PEEK Cage (4 Locking Screws)

Following implantation, proper postoperative care is essential to ensure healing and prevent complications:

Immediate postoperative X-ray or CT to confirm implant positioning

Early ambulation typically allowed; cervical collar prescribed per surgeon preference

Neck rehabilitation focusing on stabilization

Monitor for subsidence or cage migration in serial imaging at 3, 6, and 12 months

Watch for dysphagia or adjacent segment degeneration; incidence is lower vs. plate systems



Conclusion


The Cervical PEEK Cage (4 Locking Screws) offers advanced stand‑alone fixation for ACDF procedures, combining multi-screw mechanical anchorage with a zero‑profile, radiolucent implant body. It delivers low subsidence risk, reduced soft tissue complication, and clear imaging follow-up—while matching plate-assisted constructs in fusion success for one- to two-level surgeries. CE‑ and ISO‑certified, it reflects modern expectations in safety and surgical efficiency.


FAQs of Cervical PEEK Cage (4 Locking Screws)



Does the four-screw design prevent migration better than two-screw cages?


Yes—quad-screw fixation enhances resistance to shear, torsion, and migration by anchoring at multiple points in both vertebral bodies.


Is the fusion rate comparable to plate‑augmented systems?


Clinical studies demonstrate similar fusion success for one- and two-level constructs, with some loss of lordosis and higher subsidence in multilevel stand-alone cages.


Is the incidence of dysphagia lower than with plate cages?


Yes—the zero‑profile design without an anterior plate reduces soft tissue irritation and swallowing complications.


Can it be used for three-level ACDF?


While technical possible, clinical evidence suggests plate-assisted systems may better preserve alignment and reduce subsidence in ≥3-level constructs.


Are screws self-locking and self-tapping?


Yes—screws engage bone directly and lock without additional hardware, simplifying insertion workflow.
