® AVS Anchor-C Cervical Cage System Biomechanical Review • Locking Mechanism Performance • Expulsion Performance • Fatigue Torsion • Fatigue Axial Compression System Overview AVS® Anchor-C is an interbody fusion device with internal screw fixation and is intended to be used in anterior cervical discectomy and fusion procedures. This system integrates a hollow PEEK cage with a titanium screw locking mechanism and is designed to aid in cervical interbody fusion. A tantalum marker is embedded into the cage to help visually confirm the posterior position under fluoroscopy. The integrated design allows for rigid screw fixation without any added anterior profile. AVS® Anchor-C screws feature an outer clip which engages the titanium face plate on the cage. The interbody device is offered in a variety of lengths, heights and lordotic angles. Biomechanical Testing The AVS® Anchor-C Cervical Cage System promotes stability to the cervical spine during fusion by integrating a hollow PEEK cage with a titanium screw clip locking mechanism. The system allows for rigid screw fixation without any added anterior profile. The AVS® Anchor-C Cervical Cage System was shown to be mechanically sound in a series of biomechanical tests designed to challenge the structural integrity of the system. Biomechanical tests included locking mechanism performance, expulsion performance, fatigue torsion, and fatigue axial compression and were conducted in accordance with the applicable American Society for Testing and Materials (ASTM) standards.
