## Indications for use
The Anterior Lumbar Buttress System is intended for anterior intravertebral body screw fixation/attachment to the LI -SI spine over one vertebral body extending onto the adjacent intervertebral space. Due to variations in the anatomy, the plate is designed for applications caudal to the bifurcation of the great vessels. Specifically, the device is intended for stabilization and buttressing of bone graft over one motion segment following anterior structural reconstruction for degenerative disc disease (DDD). DDD is defined as follows: back pain of a discogenic origin with degeneration of the disc confinned by history and radiographic studies.
