A Clinical Comparison of Anterior Cervical Plates versus Stand-Alone Intervertebral Fusion Devices for Single-Level Anterior Cervical Discectomy and Fusion Procedures

Abstract Objective To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fus...

Description
Summary:Abstract Objective To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fusion (ACDF) procedures. Methods This multicenter, randomized, prospective study included 54 patients with degenerative disc disease (DDD) requiring ACDF at a single level at C3–C7. Twenty-six patients underwent single-level ACDF with stand-alone spacers (SA), and 28 with plate fixation and spacers (PS). Analyses were based on comparison of perioperative outcomes, radiological and clinical metrics, and incidence of dysphagia and/or dysphonia. Results Mean patient age was 48.8±10.1years (53.7% female). No significant differences were observed between groups in operative time (101.8±34.4min, 114.4±31.5min), estimated blood loss (44.8±76.5cc, 82.5±195.1cc), or length of hospital stay (1.2±0.6days, 1.3±0.6days). Mean visual analog scale (VAS) pain scores and Neck Disability Index (NDI) scores improved significantly from preoperative to last follow-up (10.8±2.6mo) in both groups ( P
