In Vitro Analysis of Stability, and Potential Risks Associated with a Novel Cervical Interbody Device with Anchors: A Microtomography Study

BACKGROUND CONTEXT: Single- and multilevel anterior cervical discectomy and fusion (ACDF) achieves excellent rates of fusion. Stand-alone implants with integrated screws or anchored implants are known to reduce retraction, dysphagia and irritation to paravertebral soft tissue, but these devices may pose concerns regarding relocation, movement or potential damage to the vertebral body (VB) due to insertion of the anchor through the boney endplate.
