## Indications for use
Calibrate LTX Interbody System The Calibrate LTX Interbody System is indicated for spinal fusion procedures from T1 to S1 in skeletally mature patients for the treatment of a symptomatic degenerative disc disease (DDD), degenerative spondylolisthesis, spinal stenosis, and/or thoracic disc herniation (myelopathy and/or radiculopathy with or without axial pain) at one or two adjacent levels. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. Additionally, the Calibrate LTX Interbody System can be used as an adjunct to fusion in patients diagnosed with multilevel degenerative scoliosis and sagittal deformity. The Calibrate LTX Interbody System is intended for use on patients who have had at least six months of non-operative treatment. It is intended to be used with autograft and/or allogenic bone graft comprised of cortical, cancellous, and/or corticocancellous bone, and/or demineralized allograft bone with bone marrow aspirate, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion. The system is intended to be used with supplemental fixation systems that are cleared by FDA for use in the thoracic and lumbar spine. Calibrate LTX spacers expanded greater than 20° have integrated fixation tabs and must be used with LTX bone screws in addition to supplemental fixation. Calibrate LTX spacers without integrated fixation tabs may be used with AMP-LTX System as integrated fixation in addition to supplemental fixation. Calibrate NanoTec LTX Interbody System The Calibrate LTX Interbody System with advanced NanoTec surface treatment is indicated for spinal fusion procedures from T1 to S1 in skeletally mature patients for the treatment of a symptomatic degenerative disc disease (DDD), degenerative spondylolisthesis, spinal stenosis, and/or thoracic disc herniation (myelopathy and/or radiculopathy with or without axial pain) at one or two adjacent levels. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. Additionally, the Calibrate NanoTec LTX Interbody System can be used as an adjunct to fusion in patients diagnosed with multilevel degenerative scoliosis and sagittal deformity. The Calibrate NanoTec LTX Interbody System is intended for use on patients who have had at least six months of non-operative treatment. It is intended to be used with autograft and/or allogenic bone graft comprised of cortical, cancellous, and/or corticocancellous bone, and/or demineralized allograft bone with bone marrow aspirate, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion. The system is intended to be used with supplemental fixation systems that are cleared by FDA for use in the thoracic and lumbar spine. Calibrate NanoTec LTX spacers expanded greater than 20° have integrated fixation tabs and must be used with AMP-LTX bone screws in addition to supplemental fixation. Calibrate Nanolec LTX spacers without integrated fixation tabs may be used with AMP-LTX System as integrated fixation in addition to supplemental fixation.
