## Indications for use
The intended use of the UCR Spinal System, polyaxial screws, polyaxial reduction screws, cross links, crossbars, rods, caps, set screws, and components, is substantially equivalent to the intended use of the predicate device. The intended use of the UCR Spinal System is as a temporary or permanent posterior, non-cervical implant to correct spinal disorders and provide stabilization of the spine to permit the biological process of spinal fusions to occur. The intended use of the UCR Spinal System, when used as a Pedicle Screw Spinal System or Spondylolisthesis Spinal Fixation Device System, is to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine. The indications for use are as follows: * degenerative disc disease (DDD) as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies, * severe spondylolisthesis (Grades 3 and 4) of the L5-SI vertebra in skeletally mature patients receiving fusions by autogenous bone graft having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the implants after the attainment of a solid fusion (indication for use only when used as a Spondylolisthesis Spinal Fixation Device System), * spondylolisthesis, * trauma (i.e., fracture or dislocation), * spinal stenosis, The intended use and indications of the UCR Spinal System, when used as a Spinal Interlaminal Fixation Orthosis or Hook Spinal System, are limited to Ti-L5 and are as follows: * degenerative disc disease (DDD)) as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies, * spondylolisthesis * trauma (i.e., fracture or dislocation), * spinal stenosis, * deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis), * tumor, *pseudarthiosis, and/or *failed previous fusion.
