## Indications for use
When used as a pedicle screw fixation system of the non-cervical posterior spine in skeletally mature patients using bone graft, the TSRH-I Spinal System is indicated as an adjunct to fusion for one or more of the following: (I) degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), (2) degenerative spondylolisthesis with objective evidence of neurologic impairment, (3) fracture, (4) dislocation, (5) scoliosis, (6) kyphosis, (7) spinal tumor, and/or (8) failed previous fusion (pseudarthrosis). In addition, when used as a pedicle screw fixation system, the TSRH9 Spinal System is indicated as an adjunct to fusion for skeletally mature patients using bone graft: (1) having severe spondylolisthiesis (Grades 3 and 4)of thiefifth lumbar-first sacral (L5-SI) vertebral joint: (2) whioare receiving fusions usinig autogenous bone graft only: (3) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (4) who are having the device removed after the development of a solid fusion mass. When used as a posterior, non-cervical, non-pedlicle screw fixation system, the TSRH® Spinal System is intended for the following indications: (1) degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), (2) spondylolisthesis, (3) fracture, (4) spinal deformities (i.e., scoliosis, kyphosis, and/or lordosis), (5) spinal stenosis, (6) pseudarthrosis, (7) tumor resection, and/or (8) unsuccessful previous attempts at spinal fusion. When used as a unilateral supplemental fixation device in the antero-lateral thoracic/lumnbar region, the TSRH-I L-Plate and VANTAGETM screws are intended for the following indications: spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis and/or lordosis); tumor; pseudarthritis; and/or failed previous fusion. For anterior use only the TSRH® Spinal System has the additional indication of. spondylolysis.
