CERVICAL CAGE(RE CAGE)
A cervical cage, also known as a re-cage, is an orthopedic implant used in cervical spine surgeries to provide stabilization, restoration of disc height, and promotion of fusion between cervical vertebrae. Here's an overview of its specifications and uses:
Specification
- Material: Cervical cages are typically made from biocompatible materials such as titanium, titanium alloy, or polyetheretherketone (). These materials offer strength, durability, and compatibility with bone tissue.
- Design: Cervical cages have a cylindrical or box-shaped design with hollow interiors. They are available in various sizes to accommodate different patient anatomies and surgical requirements. The design may also include features such as teeth or ridges to prevent migration and improve stability within the disc space.
- Surface Texture: The surface of the cervical cage may be treated or coated to promote bone growth and fusion. This can include features such as roughened surfaces, porous coatings, or hydroxyapatite coatings that enhance osseointegration.
- Graft Windows: Cervical cages often feature windows or perforations along the surface to allow for the placement of bone graft material. These graft windows facilitate the incorporation of bone graft into the intervertebral space, promoting fusion between adjacent cervical vertebrae.
- Plate Design: Some cervical cages may include an integrated plate or fixation mechanism to provide additional stability and support. The plate may be attached to the cage or placed separately during surgery, depending on the surgical technique and specific patient needs.
Uses
- Spinal Fusion Surgery: The primary use of a cervical cage is in cervical spine fusion surgeries. It helps restore and maintain disc height, stabilize the spine, and promote fusion between adjacent cervical vertebrae. The cage serves as a spacer to facilitate bone growth and fusion across the disc space.
- Correction of Spinal Deformities: Cervical cages can be used to correct spinal deformities such as cervical disc degeneration, herniation, or spondylolisthesis. By providing structural support and realignment of the cervical spine, the cage helps alleviate symptoms and improve spinal stability.
- Interbody Fusion: Cervical cages facilitate interbody fusion by providing a stable platform for the placement of bone graft material. They allow for the ingrowth of bone tissue across the disc space, leading to fusion between adjacent cervical vertebrae and stabilization of the spinal segment.
- Minimally Invasive Surgery: Cervical cages are suitable for use in minimally invasive cervical spine surgeries, where access to the surgical site is limited. Their design allows for easier insertion through smaller incisions while still providing adequate stability and fusion promotion.
- Revision Surgery: Cervical cages may be used in revision spinal surgeries to augment or replace existing interbody implants. They can provide additional stability and support in cases where previous implants have failed or require modification.
In summary, a cervical cage, or re-cage, is a versatile implant used in various cervical spine surgeries to provide stabilization, restoration of disc height, and promotion of fusion between cervical vertebrae. It offers customization, stability, and fusion-promoting properties essential for successful outcomes in cervical spine surgery.
