EXPANDEBAL CAGE WITH PLATE
An expandable cage with a plate is an orthopedic implant used in spinal fusion surgeries, particularly in the cervical or lumbar spine. Here's an overview of its specifications and uses:
Specification
- Material: The cage and plate are typically made from biocompatible materials such as titanium or titanium alloy. These materials are chosen for their strength, durability, and compatibility with bone tissue.
- Design: The expandable cage with a plate is designed to be inserted into the intervertebral space between vertebral bodies. The cage is initially in a compressed state for insertion and then expanded to fit the desired height and width within the disc space. The plate is attached to the cage and provides additional stability and support.
- Expandability: The expandable cage allows for controlled expansion after insertion, enabling surgeons to restore disc height, correct spinal alignment, and provide adequate decompression of neural structures. This feature allows for customization of the implant based on patient anatomy and surgical requirements.
- Plate Design: The plate attached to the cage may have various configurations, such as a straight or curved shape, to accommodate different spinal curves and anatomical variations. It may also have screw holes or other fixation mechanisms for securing the cage in place.
- Surface Texture: The surface of the cage and plate 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.
Uses
- Spinal Fusion Surgery: The primary use of an expandable cage with a plate is in spinal fusion surgeries to restore disc height, stabilize the spine, and promote fusion between adjacent vertebrae. The expandability of the cage allows for precise restoration of disc height and alignment, facilitating successful fusion.
- Correction of Spinal Deformities: The implant can be used to correct spinal deformities such as degenerative disc disease, herniated discs, or spondylolisthesis by providing structural support and realignment of the spinal column.
- Interbody Fusion: The cage with a plate facilitates interbody fusion by providing a stable platform for the placement of bone graft material. It allows for 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: The expandable cage with a plate is suitable for use in minimally invasive spinal fusion surgeries, where access to the surgical site is limited. Its expandability allows for insertion through a smaller incision while still providing adequate stability and fusion promotion.
- Revision Surgery: The implant may be used in revision spinal surgeries to augment or replace existing interbody implants. It can provide additional stability and support in cases where previous implants have failed or require modification.
In summary, an expandable cage with a plate is a versatile implant used in various spinal fusion surgeries to provide stabilization, restore disc height, correct spinal deformities, and promote fusion between adjacent vertebrae. It offers customization, stability, and fusion-promoting properties essential for successful outcomes in spinal surgery.
