The Lumbo-Space PLIF device is intended to serve as a spacer in Posterior Lumbar Interbody Fusion (PLIF) procedures. The primary function of the device is to distract and to restore the intervertebral space. The Lumbo-Space PLIF device is available in various shapes and sizes (lordotic and parallel). The design promotes bony fusion of the disc space and allows - if required - to achieve a lordotic spine segment. The Lumbo-Space PLIF device is manufactured from the radiable material PEEK-OPTIMA™. The implant includes small Tantalum markers in order to provide a radiographic visibility.
