## Indications for use
The CD HORIZON® Spinal System with or without SEXTENT® instrumentation is intended for posterior, non-cervical fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis and/or lordosis); tumor; pseudarthritis; and/or failed previous fusion. Except for hooks, when used as an anterolateral thoracic/lumbar system, the CD HORIZON® Spinal System may also be used for the same indications. With the exception of degenerative disc disease, the CD HORIZON LEGACY 3.5mm rods and the CD HORIZON® Spinal System PEEK rods and associated components may be used for the aforementioned indications in skeletally mature patients. The CD HORIZON® SPIRE Plate is a posterior, non-pedicle supplemental fixation device intended for use in the non-cervical spine (TI-S1). It is intended for plate fixation/attachment to spinous processes for the purpose of achieving supplemental fusion in the following conditions: degenerative disc disease (as previously defined); spondylolisthesis, trauma; and/or tumor. In order to achieve additional levels of fixation, the CD HORIZON® Spinal System rods may be connected to the VERTEXTM Reconstruction System with the VERTEXTM rod connector. Refer to the VERTEXTM Reconstruction System Package Insert for a list of the VERTEXTM indications of use.
