Description
The SIGNUS TETRIS™ ST and SIGNUS TETRIS™ R ST system is an intervertebral fusion device to treat degenerative disc disease. The implants are additively manufactured from titanium alloy (Ti-6Al-4V). Each device is available in a single footprint, with multiple heights and angulations. The SIGNUS TETRIS™ ST/ TETRIS™ R ST device is placed by a PLIF (Posterior Lumbar Interbody Fusion) approach in the L2 – S1 spinal region and should be inserted in pairs. The device is comprised of structural titanium in an open-pore grid structure. The large fenestration in the implant permits the cage to be packed with autogenous bone graft and/or allograft comprised of cancellous and/or corticocancellous bone graft to facilitate fusion.
