Posterior Lumbar Interbody Fusion
Posterior lumbar interbody fusion (PLIF) is today the gold standard in the treatment of degenerative disc disease. The TETRIS™ Lumbar Fusion Implant System is designed to provide the surgeon with an optimal method for achieving immediate and long-term biomechanical stabilization and restoration of lordosis in the lumbar spine (L1 to S1). The implants are inserted bilaterally in pairs via a posterior approach.
They are intended to restore the interbody vertebral disc height and lead to solid bony fusion when used in conjunction with supplemental posterior instrumentation of the surgeon’s choice.TETRIS™ Titan is placed by a PLIF (Posterior Lumbar Interbody Fusion) approach in the L1 – S1 spinal region and should be inserted in pairs. The large fenestration in the implant permits the cage to be packed with natural or synthetic bone graft substitute such as KAINOS® Inject.
The inserted cages, combined with additional posterior instrumentation, lead to immediate biomechanical stabilisation. This establishes the ideal conditions for vertebral body fusion.
The large selection of implants provides for a high degree of intra- operative flexibility and ensures restoration of the intervertebral space. In addition to plane-parallel implants, the TETRIS™ Titan cage is also available with a 4° lordotic angle.The implants consist of biocompatible titanium (Ti-6Al-4V) with proven strength.
