Optima® ZS Spinal Fixation System

Product Description

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.


  • Polyaxial screws feature a 57 degree conical range of motion, facilitating rod placement
  • Cylindrical outer and conical inner screw thread diameters maximize purchase and resist pull-out
  • Closure tops feature a square thread design, reducing the risk of cross-threading and allowing for a low profile tulip head design
  • Spherical micro-ridges on the screw shank head ensures solid circumferential locking
  • Screws are color-coded by size, easing intraoperative recognition

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


  • Any active or suspected latent infection in or about the spine
  • Any mental or neuromuscular disorder which would create an unacceptable risk of fixation failure or complications in post-operative care
  • Bone stock compromised by disease, infection or prior implantation which cannot provide adequate support and or fixation to the implant
  • Obesity: an overweight or obese patient can produce loads on the spinal system which can lead to failure of the fixation of the device or to failure of the device itself
  • Recent infection, fever or leukocytosis
  • Bony abnormalities preventing safe screw fixation
  • Open wounds
  • Metal sensitivity, documented or suspected
  • Bone absorption, osteopenia and/or osteoporosis
  • Patients having inadequate tissue coverage over the operative site
  • Pregnancy
  • Excessive local inflammation

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.
