## Indications for use
It is intended that this device, in any system configuration be removed after development of solid fusion mass. Hook component indications are limited to T7-Lb. Sacral screw indications are limited to the sacrum only. 1) The ZODIAC TM Spinal Fixation System when used as a hook and sacral screw fixation system (nonpedicle screw) is intended for: a. Patients having fractures of the thoracic and lumbar spine. b. Patients having deformity (i.e., idioscoliosis, neuromuscular scoliosis, or kyphoscoliosis with associated paralysis or spasticity). c. Patients having spondylolisthesis (i.e., isthmic spondylolisthesis, degenerative spondylolisthesis, and acute pars fracture allowing spondylolisthesis). 2) The ZODIACTM Spinal Fixation System, when used as a pedicle screw system in the thoraco-lumbo-sacral region of the spine is intended for degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor and failed previous fusion (pseudoarthrosis). 3) In addition, the ZODIACTM Spinal Fixation System, when used as a pedicle screw fixation system is intended for: a. Patients receiving only autogenous bone graft. b. Patients having the device fixed or attached to the lumbar and sacral spine and having severe spondylolisthesis grade 3 or 4 at the fifth lumbar-first sacral (L5-Si) vertebral joint. 4) The ZODIAC T Spinal Fixation System, when used as a laminar hook and bone screw system is intended for: a. Patients having fractures of thoracic and lumbar spine. b. Patients having thoracolumbar deformity (i.e., idioscoliosis, neuromuscular scoliosis, or kyphoscoliosis with associated paralysis or spasticity). c. Patients having spondylolisthesis (i.e., isthmic spondylolisthesis, degenerative spondylolistheses and acute pars fracture allowing spondylolisthesis).
