## Indications for use
This anterolateral / anterior system consists of several vertebral screws, locking nuts, spine plates and rods. The points of attachment are screw fixation to the anterolateral vertebral bodies of the lumbar and thoracic spine (TI-L5). This system is intended to provide stabilization during the development of a solid spinal fusion. When used as an anterolateral / anterior spine plate and rod system, the MACS Modular Anterior Construct System is indicated for patients with: Degenerative disk disease defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies Spondylolisthesis Spondylolysis Fracture Spinal stenosis Deformities (i.e., scoliosis, kyphosis, lordosis, whether neuromuscular or related to deficient posterior elements) Tumors (neoplastic disease) Pseudarthrosis Revision of previous surgery
