Solvay reports that its Zeniva polyether ether ketone (PEEK) material has been used to make the first non-metal lumbar cage for vertical interbody fusion made in Japan.
KiSCO machined the spinal cage from Zeniva ZA-500 PEEK which is made in compliance with ISO 13485. According to Solvay, Zeniva PEEK has improved fatigue resistance and a modulus similar to bone and can facilitate post-operative diagnosis because its radio transparency allows for easy visualization in medical X-ray and MRI imaging.
The primary function of a spinal cage is to maintain the proper intervertebral angle and height until spinal fusion occurs. However, spinal cages also need to accelerate bone fusion and support adjustments during surgery, Solvay says.
