The Cervical Cage (Square Cage) – Spacer is a fixed interbody fusion device used in the cervical spine during Anterior Cervical Discectomy and Fusion (ACDF) procedures. It is a square or rectangular cage designed to be placed into the disc space after the disc material has been removed. The cage maintains the proper height and alignment of the vertebrae (lordosis) and is packed with bone graft material to promote fusion. The large fenestrations (windows) allow for maximum contact between the bone graft and the vertebral endplates, encouraging solid fusion.
Key features include:
-
Fixed Height Design: Used as a non-expanding spacer to maintain disc height and alignment.
-
Square/Rectangular Footprint: Provides maximum contact area with the vertebral endplates for stability.
-
Primary Use: Anterior Cervical Discectomy and Fusion (ACDF).
-
Multiple Footprints: Available in fixed footprints: 12 x 12mm, 14 x 12mm, and 16 x 12mm (Length x Width).
-
Height Variation: The height (Size) is available in a range from 6mm to 10mm.
-
Material: Typically made of PEEK or Titanium (implied by this category of spinal implant).
