ALTERA® is an articulating expandable TLIF spacer designed to increase disc height, restore lordosis, and maintain sagittal balance.
- Continuous Expansion: Up to 4mm of continuous expansion to restore disc height and optimize endplate-to-endplate fit.
- Minimal Insertion Height: Inserted at a reduced height to minimize impaction and preserve endplate integrity.
- Optimal Placement: Integrated articulation provides steerable placement within the anterior disc space.
