TRANSFORAMINAL LUMBAR INTERBODY FUSION (TLIF) is a well – accepted advanced approach for spinal fusion surgery suitable for the treatment of disc prolapse, discogenic back pain, Lumbar canal and/or lateral recess stenosis, Spondylolisthesis, where conservative treatments have failed. The Tlif approach avoids significant retraction of the dura and nerve roots which exposes the nerves to a lower risk of injury and also requires less muscle retraction. NEO T-desmos offers a highly stable, anatomical solution for restoration of intervertebral disc height, specifically designed to accept bone graft and maximize bone growth. NEOTdesmos is biocompatible, made of peek, a naturally radiolucent polymer which provides optimal radiographic visualization with imaging techniques such as X-Ray, MRI, and CT NEOTdesmos is anatomically shaped and available in two types with 2° or 5° Lordosis. The jagged surfaces facilitate stable fixation.
