Posterior Lumbar Interbody Fusion

Two implants - one reliable treatment

The TETRIS II cage combines the biomechanical properties of PEEK-OPTIMA with a slender design for posterior implantation. The geometric design of the tip facilitates insertion of the implant, rendering the surgical procedure safer and less aggressive. The position of the cage is easy to determine thanks to the tantalum X-ray markers.
TETRIS II PEEK is used in combination with posterior stabilization of spinal segments L1 to S1, in the following indications:


The MONOPOLY II pedicle screws are designed to deliver improved anchorage in bone that is of lower density (osteoporosis).
The indications therefore comprise osteoporosis, metastatic bone neoplasms (secondary or primary), revision surgery, and rheumatic diseases accompanied by poor bone density/quality.
