Abstract
From April 2011 to April 2013 a total of 63 consecutive patients with cervical degenerative disc disease who underwent one or twolevel ACDF using either the zeroprofile anchored spacer or the standalone cages and a titanium plate fixation were reviewed for the radiological and clinical outcomes and complications The zeroprofile anchored spacers were used in 30 patients anchored group and standalone cages with an anterior cervical plate were implanted in 33 cases nonanchored group Operative time intraoperative blood loss clinical and radiological results were compared between the anchored group and the nonanchored groupAll patients were followed up for at least 12 months There were not bolt loosening or rupture of anchoring clips screws or titanium plates observed in two groups during followup period There were no significant difference in neck disability index scores Japanese Orthopedic Association scores fusion rate and cervical lordosis during followup between two groups P 005 but significant difference in the operation time blood loss and the presence of dysphagia were found P 005 There were no adjacent disc degeneration and instability observed in two groupsThe zeroprofile anchored spacer achieved similar clinical outcomes compared to ACDF with anterior plating for the treatment of the cervical degenerative disc disease However zeroprofile anchored spacer was associated with a lower risk of postoperative dysphagia shorter operation time less blood loss and relatively greater simplicity than the standalone cage with a titanium plate
