An expandable jack cage with plate is a sophisticated spinal implant system that integrates a mechanically expandable interbody cage (jack mechanism) with a built-in fixation plate and locking screws. This design allows surgeons to insert the cage in a collapsed profile, position it accurately within the intervertebral space, and then expand it in situ to restore disc height, spinal alignment, and segmental lordosis.

The jack-based expansion mechanism enables precise and controlled vertical distraction, ensuring optimal contact with vertebral endplates while minimizing the risk of subsidence or implant migration. Once expanded, the integrated plate is secured to the adjacent vertebral bodies using screws, providing immediate stability and eliminating or reducing the need for additional anterior plating systems.

The cage includes large graft chambers to accommodate bone graft material, promoting osseointegration and long-term fusion. Its surface design often incorporates texturing or serrations to enhance fixation and stability.

Manufactured from medical-grade titanium, titanium alloy, or hybrid materials (such as titanium with PEEK), this system offers excellent strength, durability, and biocompatibility. The integrated design helps simplify surgical workflow, reduce operative time, and ensure a low-profile construct.

Expandable jack cages with plate are widely used in cervical and lumbar fusion procedures, especially in cases involving degenerative disc disease, spinal instability, trauma, and deformity correction, where controlled expansion and immediate fixation are essential.
