OptiStrain C Anterior Cervical Cage

OptiStrain C

The OptiStrain C cage* combines the osteogenic attributes of titanium with a load transferring design.

OptiStrain C - Optimized Strain

The OptiStrain C cage (Strain: medical unit of measurement for the elastic deflection of bone under loads) follows well established biomechanical principles: The slot design of the implant allows for reduced stress shielding and therefore enables load transfer through the device. Cyclic loading of bone stimulates bone growth in accordance to Wolff´s Law and thus supports the fusion process mechanically.

Micro Motion for Optimized Bony Fusion

The graph above illustrates:

  • Because of the stiffness of the material, titanium cages do not allow for any deflection and are very likely to cause stress shielding and subsidence
  • PEEK cages are less stiff than titanium cages, but only allow for a slight deflection under load
  • Only the OptiStrain C cage allows for an optimized load deflection. Micro-motion supports mechanical load transfer to the bone and the filling material of the cage
  • Unlike the DCI, the OptiStrain C cage does not preserve motion, but allows micro-motion to achieve a faster bony fusion

OptiStrain C

  • Optimized Load Transfer

    • Reduced stress shielding
    • Micro-motion through slot design
    • Cyclic loading of bone
    • Large central fenestration can be filled with bone graft or bone substitutes

    Reduced Risk of Subsidence

    • Optimized stiffness of the implant
    • Endplate protection through soft stop technology
    • Maximized contact surface for optimal load distribution

    Biocompatible Titanium Alloy

    • Angiogenic and osteogenic characteristics support osseointegration
    • Roughened titanium surface provides excellent primary and secondary stability

    Additional Product Features

    • Enhanced primary stability through teeth on implant surface
    • 9 anatomical sizes
    • Color coded instruments and implants
  • Indications

    The implant can be utilized for pathologies of the cervical spine which indicate segmental arthrodeses. These include, e.g.:

    • Degenerative disc disease and instabilities
    • Spinal disc herniations
    • Pseudarthrosis or failed spondylodesis

    It is indicated for patients with mature skeletons with or without myeloradiculopathy with or without neck pain.

    Surgical treatment should follow at least six weeks of conservative treatment.

    The use of a semi-rigid plate is recommended if the operating surgeon selects additional plate osteosynthesis (e.g. for multi-segmental fusions or major instability).


    Do not use the OptiStrain C cage in cases of:

    • Any medical or surgical condition precluding the potential benefit of spinal surgery
    • Acute or chronic systemic, spinal or localized infections
    • Uncontrolled systemic and metabolic diseases
    • Obesity
    • Pregnancy
    • Dependency on pharmaceutical drugs, drug abuse, or alcoholism
    • Lack of patient cooperation
    • Foreign body sensitivity to the implant material
    • Severe mechanical instability
    • Osteoporosis
    • Significant osteopenia
    • Vertebral fracture and/or tumors

    Safety Precautions

    • Prior to use, thoroughly read these instructions for use and become familiar with the surgical technique.
    • Keep the instructions for use accessible to all staff.
    • The operating surgeon must have a thorough command of both the hands-on and conceptual aspects of the established operating techniques. Proper surgical performance of the implantation is the responsibility of the operating surgeon.
    • The manufacturer is not responsible for any complications arising from incorrect diagnosis, choice of incorrect implant, incorrect operating techniques, the limitations of treatment methods or inadequate asepsis.
    • Under no circumstances may modular implant components from different suppliers be combined.
    • Each patient's record shall document the implant used (name, article number, lot number).
    • During the postoperative phase, in addition to mobility and muscle training, it is of particular importance that the physician keeps the patient well informed about post-surgical behavioral requirements.
    • Damage to the weight-bearing structures can give rise to loosening, dislocation and migration, as well as other complications. To ensure the earliest possible detection of such catalysts of implant dysfunction, the implant must be checked periodically post operative using appropriate techniques.
    • Never reuse an implant. Although the implant may appear undamaged, previous stresses may have created non-visible damage that could result in implant failure.
    • Never use implants if the packaging is damaged. An implant with damaged packaging might be damaged itself and thus may not be used.
    • Never use implants that are past their expiration date.
    • Do not resterilize implants which have been contaminated with blood or secretions.
