Orthopaedic Implants Cervical Fusion Overview

Cervical fusion devices are key implants used in spine surgery to treat degeneration, trauma or instability of the cervical spine.

Its core role is to re-establish cervical stability, restore intervertebral height and promote bony fusion.

The cervical fusion device replaces degenerated disc tissue by implanting into the diseased vertebral space.

By replacing the degenerated disc tissue, the cervical fusion device opens up the intervertebral space 

and restores the normal height and curvature of the cervical spine, thus indirectly enlarging the volume 

of the spinal canal and the nerve root canal and effectively relieving spinal cord and nerve root compression.

The PEEK locking screw is the core fixation component in the cervical peek cage system. It anchors the fusion tightly to the adjacent vertebral body by means of a locking mechanism , preventing the fusion from shifting or rotating within the intervertebral space and ensuring immediate postoperative stability.

Advantages of pairing a cervical peek cage with a cervical peek locking screw

Improved mechanical stability:

The locking nail directly anchors the fusion to the vertebral body, dispersing shear and rotational stresses during 

cervical spine movement and reducing the risk of postoperative displacement.

Avoiding the rigid fixation of traditional sheet metal screw systems reduces 

the incidence of adjacent segment degeneration (ASD).

Biological fusion optimisation:

The elastic cushioning properties of the PEEK material promote uniform growth of bone trabeculae 

and reduce bone resorption due to stress masking.

The porous structure of the fusion device (e.g., 3D-printed honeycomb pores) synergises with the active coating 

on the surface of the locking nail to promote bone ingrowth.

Convenient imaging assessment:

The PEEK material is free of metal artefacts, and the progress of bone fusion and the effect of nerve decompression 

can be clearly observed by CT/MRI after surgery.

The combination of cervical peek cage and PEEK locking screws achieves the therapeutic goal of ‘Stabilisation - Fusion - Decompression’ through material suitability, structural complementarity and surgical precision.
