The spine, a vital component of our musculoskeletal system, plays a pivotal role in our overall well-being. When issues arise, spinal cages become a critical element in addressing these concerns. This blog explores the world of spinal cages, their various types, and the diverse range of applications they serve.
Understanding of Spinal Cages
Surgeons use innovative medical devices, known as spinal cages or interbody/vertebral cages, in spinal surgery. These devices create space between vertebrae and provide crucial support during spinal fusion procedures, essential for stabilizing the spine and alleviating discomfort. By understanding the different types and uses of spinal cages, we can appreciate their profound impact on the field of spinal healthcare.
Types of Spinal Cages
Spinal cages are not one-size-fits-all. Various types have been developed to cater to different medical requirements. Here, we’ll explore some of the most common categories:
Interbody Cages: These are perhaps the most well-known. Interbody cages are inserted between vertebrae to restore the height of the disc space. By doing so, they help alleviate pressure on nerves and facilitate fusion.
Corpectomy Cages: In cases where an entire vertebral body needs to be removed due to trauma or disease, corpectomy cages come to the rescue. These implants replace the removed vertebral body, providing structural support and stabilizing the spine.
Artificial Discs: For patients who wish to preserve spinal motion, artificial discs are an option. These devices replicate the natural function of a disc and serve as an alternative to traditional fusion procedures.
I. Dio Cage:
The Dio Cage is a type of interbody spinal cage used in spinal fusion procedures. These devices are typically crafted from durable materials; notably, titanium or PEEK (polyetheretherketone) is commonly used, ensuring their suitability for medical applications. The Dio Cage is designed for insertion between adjacent vertebrae to maintain disc space height and promote fusion. This type of cage provides stability and support to the spine, which is essential in addressing conditions like degenerative disc disease and spondylolisthesis.
- Simplify surgery for quicker procedures.
- Maximize bone fusion with a large grafting area.
- Enable 3D visualization and radiological precision with X-ray markers.
- Optimize graft material use and enhance end plate contact.
- Choose between biocompatible, corrosion-resistant PEEK and Titanium.
- Ensure reliability with corrosion resistance, precision construction, permanent finish, and robust bone support.
II. Expandable Cage:
Expandable cages offer a high degree of versatility. They can be dynamically adjusted in size during surgery, thus allowing for a customized fit tailored to the specific needs of individual patients. This adaptability makes them an excellent choice in various clinical scenarios. Surgeons can customize the cage’s dimensions to fit the patient’s specific anatomical requirements. These cages are particularly useful when dealing with complex spinal conditions or when minimally invasive procedures are preferred. The expandable nature of these cages allows for a more precise and patient-tailored approach to spinal fusion.
- Emphasizes ease of insertion and quick positioning for minimal invasiveness.
- Ensures dependable performance with precise dimensions.
- Maximizes anatomical fit through an anterior cervical approach.
- Optimizes load distribution between the implant and vertebrae.
- Allows continuous expansion to achieve the desired height.
- Maintains stable implant height without additional steps.
- Offered in Titanium material for added options.
III. Expandable Cage with Plate:
The expandable cage with a plate combines the benefits of an expandable cage with an additional plate for increased stability. This configuration offers enhanced structural support and is commonly used in cases where a high degree of stability and fusion is required. The plate provides additional fixation to promote successful fusion and long-term spine health.
- Facilitates a minimally invasive approach, simplifying insertion and quick positioning.
- Ensures consistent performance with precise dimensions.
- Maximizes the anatomical fit through an anterior cervical approach.
- Optimizes the distribution of load between the implant and vertebrae.
- Permits continuous expansion to attain the desired height.
- Maintains stable implant height without the need for extra steps.
- Comes in Titanium material as an available option.
IV. Mesh Cage:
A mesh cage is a unique variation of spinal cage that features an open or mesh-like structure. This design allows for better fusion through the incorporation of bone graft material. Mesh cages are often used in conjunction with bone grafts to promote bone growth and fusion between vertebral segments. They provide an environment conducive to bone ingrowth and fusion.
- Used in corpectomy to preserve intervertebral height.
- Offered in various heights to suit specific pathology and anatomy.
- Features an open design to encourage bony fusion and bone ingrowth.
- Equipped with parallel end rings to restore spinal alignment and prevent subsidence.
- Mesh cages find utility in cervical and lumbar areas.
- Available in diameters of 12, 14, 16, and 18 millimeters (mm).
- Titanium material is a viable option.
V. PLIF Bullet Type Cage:
The Posterior Lumbar Interbody Fusion (PLIF) Bullet Type Cage is specially designed for PLIF procedures. It has a bullet-shaped or tapered structure that allows for easier insertion into the intervertebral space. These cages offer good load-bearing capabilities and support for fusion. PLIF Bullet Type Cages are popular choices for addressing lumbar spine issues.
- Designed for treating lumbar degenerative disc disease.
- Facilitates fusion of painful vertebral segments to halt painful motion.
- Constructed from Titanium grade 5 and PEEK materials for durability and biocompatibility.
- Available in various lengths and sizes for surgeon flexibility and patient customization.
VI. TLIF Cage:
Transforaminal Lumbar Interbody Fusion (TLIF) Cages are designed for TLIF procedures. They are characterized by their unique shape, featuring larger anterior and smaller posterior portions. The design promotes stability and support, in addition to facilitating the insertion of bone graft material, thereby aiding in the fusion process. TLIF Cages are frequently used in cases of lumbar spine pathologies.
- Allows for fusion via the cage
- Osseointegration and fusion occur quickly and directly.
- Insertion simplified with an anatomical shape available in a variety of widths and heights
- Clear and postoperative visual evaluation of imaging, including X-rays, CT scans, and MRI
- Can be used to maintain the height between two vertebrae in the Lumbar region.
- The bullet nose design for self-distraction facilitates insertion.
- Surface self-guiding rails are designed to guide and turn the cage into the desired position.
- The pivoting mechanism, in conjunction with the applicator, is enabled by the connecting post.
Uses of Spinal Cages
Spinal cages have a wide range of applications in the field of spinal healthcare:
Degenerative Disc Disease: Patients suffering from degenerative disc disease find relief through cage implantation, which alleviates pain and restores spine stability.
Spondylolisthesis – A challenging condition for individuals to manage, can greatly benefit from the application of spinal cages. These medical devices are designed not only to help realign and stabilize the spine but also to effectively prevent further slippage.
Herniated Discs: Spinal cages reduce pressure on nerves affected by herniated discs, providing relief to those suffering from excruciating pain.
Spinal Tumors: After the surgical removal of spinal tumors, cages play a crucial role in stabilizing the spine and preventing deformities.
Post-Traumatic Stabilization: Surgeons can address spinal fractures or severe trauma by implanting cages, which offer structural support and promote healing.
Scoliosis: In cases of scoliosis, surgeons use specific types of cages to correct the curvature of the spine, thereby improving the patient’s quality of life.
