The Kidney Cage is a fixed interbody fusion device characterized by its crescent or kidney-shaped footprint, designed primarily for oblique insertion techniques like PLIF (Posterior Lumbar Interbody Fusion) or TLIF (Transforaminal Lumbar Interbody Fusion). Its lordotic design, indicated by the “Degree” variants (4, 8, and 11 degrees), helps to restore the natural curvature of the lumbar spine. The shape allows for optimal placement near the anterior column of the spine, maximizing support while providing a large chamber for bone graft material to promote solid fusion. The size refers to the anterior height of the cage.
Key features include:
-
Kidney-Shaped Footprint: Optimized for posterior or transforaminal insertion and maximizing endplate contact.
-
Lordotic Angle: Available in 4, 8, and 11-degree angles to restore sagittal alignment (lumbar lordosis).
-
Primary Use: Lumbar Interbody Fusion (PLIF/TLIF).
-
Height Variation: Available in heights from 7mm to 11mm.
-
Material: Typically made of PEEK or Titanium (implied by the colored/material options shown).
