The Jack Cage with Plate is an advanced spinal implant used for Vertebral Body Replacement (VBR) or complex interbody fusion, primarily in the lumbar and thoracic spine. It is a fusion cage with an integrated, fixed or articulated plate attached to the body of the cage. The plate component provides immediate anterior column stability, preventing expulsion and reducing the need for separate anterior plate fixation. The “Jack” mechanism likely refers to its ability to be expanded or ‘jacked up’ in situ to restore disc height and lordosis.
Key features include:
-
Integrated Plate: Provides enhanced stability and fixation compared to a standalone cage, simplifying the surgical procedure.
-
Primary Use: Vertebral body replacement, correcting height loss, and providing rigid anterior column support in the lumbar/thoracic spine.
-
Modular Sizes: Available in three different diameters: 12, 14, and 16.
-
Standardized Dimensions: Available in four fixed length options (Length x Width): 20 x 25mm, 25 x 32.5mm, 35 x 32.5mm, and 35 x 42.5mm.
-
Material: Often made of Titanium (implied by typical spinal hardware standards).
