TLIF CAGE II TYPE (TT)
TLIF (Transforaminal Lumbar Interbody Fusion) cages, also known as TLIF Cage II type, are orthopedic implants used in spinal fusion surgeries, particularly in the lumbar spine. Here's an overview of their specifications and uses:
Specification
- Material: TLIF cages are typically made from biocompatible materials such as polyetheretherketone (), titanium, or titanium alloy. cages are radiolucent, allowing for clear visualization on imaging studies post-surgery.
- Design: TLIF cages are designed to fit within the intervertebral space and mimic the natural anatomy of the disc space. They may have various configurations, including a rectangular or trapezoidal shape, with hollow centers or perforations for bone graft incorporation and fusion.
- Dimensions: TLIF cages come in various sizes to accommodate different patient anatomies and surgical requirements. The dimensions of the cage are selected based on factors such as the size of the intervertebral space, the degree of disc degeneration, and the desired height restoration.
- Surface Texture: The surface of TLIF cages may be textured or coated to enhance osseointegration and stability within the intervertebral space. Textured surfaces or coatings promote bone ingrowth and fusion, ensuring long-term stability of the spinal construct.
- Graft Windows: TLIF cages often feature graft 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 vertebral bodies.
Uses
- Spinal Fusion Surgery: TLIF cages are primarily used in spinal fusion surgeries to restore disc height, stabilize the spine, and promote fusion between adjacent vertebrae. They are inserted into the disc space following removal of the intervertebral disc to provide structural support and maintain spinal alignment.
- Correction of Spinal Deformities: TLIF cages may be used in the correction of spinal deformities such as degenerative disc disease, spondylolisthesis, or spinal stenosis. By restoring disc height and decompressing neural structures, TLIF cages help to alleviate symptoms and improve spinal stability.
- Interbody Fusion: TLIF cages facilitate interbody fusion by providing a stable platform for the placement of bone graft material. The cage promotes the ingrowth of bone tissue across the disc space, leading to fusion between adjacent vertebral bodies and stabilization of the spinal segment.
- Minimally Invasive Surgery: TLIF cages are commonly used in minimally invasive spinal fusion surgeries, where access to the surgical site is limited. The design of the cage allows for insertion through a smaller incision while still providing adequate structural support and fusion promotion.
- Revision Surgery: TLIF 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.
TLIF cages, including TLIF Cage II type, play a crucial role in spinal fusion surgeries, providing structural support, stabilization, and fusion promotion between adjacent vertebral bodies. They are essential components in achieving successful fusion and stabilization of the spine.
