RANGE /DENALI/MESA and SMALL STATURE and ARI are cleared for the following indications:
Non-cervical fixation as an adjunct to fusion 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 stcnosis: curvatures (i.e. scoliosis, kyphosis and/or lordosis); tumor: pscudarthrosis: and/or failed previous fusion.
Except for hooks, when used as an anterolatcral thoracic/lumbar system the Range Spinal System may also be used for the same indications as an adjunct to fusion.
Except for the ARI staples, the Range Spinal System is indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis when used for posterior noncervical fixation in pediatric patients. The Range Spinal System for pediatric use is intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
