Transforaminal Lumbar Interbody Fusion System made of biocompatible PEEK-Optima® Description TSPACE® PEEK is an implant used for stabilization of the lumbar and thoracic spine through a transforaminal or transarticular approach, monosegmental or multisegmental. TSPACE® has been designed to fit the requirements of the minimal-invasive surgical technique. Accordingly, the innovative S4® Spinal System, the Spine Classics retractor system and the TSPACE® cage form an interesting combination for spinal fusion. Advantages - Unilateral and minimally invasive approach to the spine - Together with S4® Spinal System and the Spine Classics MLD retractor proven in hundreds of surgeries by using the mini-open technique - Wide range of implant sizes presenting the right implant to fit the patient, e. g. 1 mm increments in height - Simple and clearly arranged instruments - Three different inserters to choose: straight or curved inserter as the preference or situation in-situ may be or offset inserter for comfortable use with miscroscope or C-arm Indication Thoracolumbar spine fusion in case of: Degenerative instability, spondylolisthesis, post-discectomy syndrome and post-traumatic instabilities. Properties - The banana-like form ensures a maximized contact area between vertebrae and implant while being slim enough to be inserted through the foramen - PEEK-Optima® is transparent to X-rays and is artefact-free - Tantal markers serve as location markers - Anatomical shape and serrated profile - The bulleted nose facilitates the implantation of the cage especially in very degenerated discs - Firm connection to the inserter by means of a screw thread
