The cage serves as a space holder
between your affected vertebrae and allows the bone to grow through it,
eventually becoming a part of your spine. Cervical implants are devices
surgeons used to unwind and steady the neck.
These devices are implanted
either from the front of the spine or from the back. Spine surgeons around the
world are interested in cervical artificial discs to treat drop disease. Cervical
cage sustains most of the dorsum injuries, among other injuries,
the disc degeneration, and damage that lead to the replacement of the damaged
disc with cage or artificial disc.
Potential benefits of cervical
cages
Interbody cages aim to improve
the stability and balance of the treated cervical segment, while also relieving
pain and restoring function.
The goals of cervical cages
include:
- Restoring the height provided by the original intervertebral disc
- Supporting the front (anterior) part of the Cervical column
- Expanding the bony openings between the vertebrae, providing more space for Cervical nerves
- Restoring the normal lordotic (S-shaped) curve of the lower (lumbar) spine
- Transferring loads from the upper segments to lower sections of the spine
- Promoting a solid fusing of the adjacent vertebral segments by promoting bone growth
Increasing the spaces within the
Cervical canal to decrease the compression of neural tissue that may be
indirectly compressed
Depending on the number of
Cervical segments being fused, your surgeon may place more than one cage in
your spine.
Research suggests that 70% to 95%
of cervical fusion and 88% of lumbar fusion may be achieved when interbody
cages are used. While the role of the cervical cage is a factor for achieving a solid bony fusion, the success of
a fusion surgery depends on different parameters, such as but not limited to
the skill of the surgeon and the integrity of the nearby tissues.
Over time, some cages may undergo
Support, which can affect the fusion and stability of the treated cage segment.
Support may occur due to poor bone quality, the structure and/or material of
the cage, improper bone preparation prior to the cage placement, and other
anatomical problems.
