## Indications for use
The MOSS VRS Spinal System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine. The MOSS VRS Spinal System is intended for posterior, non-cervical pedicle fixation for the following indications: - Degenerative Disc Disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) - Spondylolisthesis - Trauma (i.e. fractures or dislocations) - Spinal Stenosis - Curvatures (i.e. scoliosis, kyphosis and/ or lordosis) - Tumor - Pseudoarthrosis - Failed previous fusion When used for posterior non-cervical pedicle screw fixation in pediatric patients, the MOSS VRS system is indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis. The MOSS VRS system is intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.
