The Cervical Vertebral Spacer is intended to serve as a spacer in Anterior Cervical Interbody Fusion (ACIF) procedures. The primary function of the device is to restore and to maintain the intervertebral space. The Cervical Vertebral Spacer is available in various shapes and sizes (lordotic in 5° or parallel 0°). The profile of the enlarged load bearing surfaces supports an initial high stability. Packing the device with cancellous bone or ?-TCP (calc-i-oss™) promotes bony fusion of the intervertebral space.
