82. Single-Site Comparison of One and Two Level Mobi-C Cervical Disc Replacement and Anterior Cervical Discectomy and Fusion Control: Preliminary Outcomes of Investigational FDA Trial

BACKGROUND CONTEXT: Anterior cervical discectomy and fusion is considered to be the standard of care in treatment of patients suffering from axial neck pain, myelopathy and radiculopathy associated with degenerative cervical disc disease. Due to the restrictive nature of ACDF, load transfers on discs adjacent to the operative site tend to increase thereby potentially increasing the rate of degeneration at those levels. Cervical disc replacement seeks to decrease pain and resolve neurological deficits while maintaining normal cervical mobility. It is expected that by preserving natural cervical movement at the surgical site, surrounding levels will not exhibit increased degenerative symptoms.
