The MINERVATM Variable Angle ACIF Cage is a stand-alone implant for use in cervical interbody fusion, which combines the functionality of a cervical interbody spacer and benefits of an anterior cervical plate.

  • Zero-profile midline designed to minimize the risk of contact with vessels and adjacent soft tissues
  • Prevents adjacent level ossification
  • Easy of use
    - Variable angle screws, designed with a wide range of allowable screw trajectories, potentially facilitate screw insertion.
    - One-step blocking mechanism features audible, tactile and visual cues to confirm screw is blocked upon insertion.
    - Small incision sizes are possible in comparison to plate and spacer usage.
  • Interbody Spacer
    - Spacer component is made of a biocompatible radiolucent polymer (PEEK) which allows visualization and assessment of the bones to be fused.
    - Teeth on the implant surface provide initial stability.
    - Radiopaque marker for posterior visualization during imaging
  • Interbody plate with stops
    Titanium alloy interbody plate provides a stable fixation with screws.
    - Stresses in the interbody plate with stops are decoupled from the spacer through an innovative interface.
    - Contralateral safety stops designed to prevent over. insertion and align with the anterior surface of the vertebral bodies.
  • Variable angle screws
    - Self-drilling and self-tapping screws.
    - Screws can be inserted 27- 44 (17 range ) in cranialcaudal direction and 15- 29 (14range) in medial-lateral direction.
    - Designed to help prevent graft expulsion.
    - Screws are allowed to toggle postoperatively within vertebral bodies, which may potentially prevent load shielding of the graft in the event of graft subsidence
