The OPTIMA ZS Spinal Fixation System is a low-profile, in-line, polyaxial pedicle screw design. The OPTIMA System gives you three-dimensional adjustability while allowing for simple, stable construct assembly.

The OPTIMA ZS Spinal Fixation System is a pedicle screw fixation system indicated for the treatment of severe spondylolisthesis (Grade 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine with removal of the implants after the attainment of a solid fusion. In addition, the OPTIMA ZS system is intended to provide immobilization and stabilization of spinal segments in skeletally-mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine: degenerative spondylolisthesis with objective evidence of neurological impairment; fracture of the vertebral body; disclocation; scoliosis; kyphosis; spinal tumor and failed previous fusion (pseudoarthrosis). When used as an anterior screw fixation system the OPTIMA ZS system is indicated for patients with degenerative disc disease which is defined as back pain of the discogenic origin with degeneration of the disc confirmed by history and radiographic studies, spondylolisthesis, fracture, spinal stenosis, spinal deformities such as scoliosis, kyphosis, lordosis, tumor, pseudoarthrosis, or revision of failed fusion attempts
Other medical or surgical conditions which would preclude the potential benefit of spinal implant surgery such as the presence of tumors, congenital abnormalities, elevation of sedimentation rate unexplained by other diseases, elevation of white blood cell count (WBC), or marked left shift in the WBC differential count.
