What is it indicated for?

The Axle Interspinous Fusion System is a posterior, non-pedicle supplemental fixation device, intended for use at a single level in the non-cervical spine (T1-S1 inclusive). It is intended for plate fixation/attachment to spinous processes for the purpose of achieving supplemental fusion in the following conditions: 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); and/or tumor. The Axle Interspinous Fusion System is intended for use with bone graft material, and not for stand-alone use.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
