The Expandable Cage is an intervertebral fusion device used in spinal surgery, primarily for Vertebral Body Replacement (VBR) or interbody fusion procedures. It is designed to be inserted into the space created after removing a damaged disc or vertebral body. The cage is then expanded in situ (in place) to restore the proper spinal height and lordosis/kyphosis, providing immediate stability and space for bone graft material to facilitate fusion. It is available in various diameters and lengths.
Key features include:
-
Expandable Design: Allows for in situ height and angle adjustment to match patient anatomy and restore spinal alignment.
-
Primary Use: Vertebral body replacement, correcting height loss due to collapse, trauma, or tumor removal.
-
Modular Sizes: Available in three different diameters: 12, 14, and 16.
-
Material: Often made of Titanium (implied by typical spinal hardware standards).
-
Multiple Lengths: Available in lengths of 20, 25, 35, 55, and 75mm.
