<jats:sec><jats:title>Study Design:</jats:title><jats:p> Systematic review and meta-analysis. </jats:p></jats:sec><jats:sec><jats:title>Objective:</jats:title><jats:p> To perform a systematic review of clinical outcomes between stand-alone anchored spacers and traditional cages with plate fixation for dysphagia and pseudoarthrosis using data from clinical trials. </jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p> Our search protocol was added to PROSPERO register and systematic review using PRISMA method was performed. Then, we systematically searched for studies addressing stand-alone anchored spacers in patients who underwent ACDF. Mean Neck Disability Index (NDI), dysphagia incidence % (Dinc%), and Swallowing–Quality of Life (SQOL) scores during preoperative, immediate postoperative and last follow-up visits were extracted. Chi-square and analysis of variance (ANOVA) tests were used for statistical comparisons ( P ≤ .05). </jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p> The initial search generated 506 articles in CENTRAL and 40 articles in MEDLINE. Finally, 14 articles were included. Total number of patients was 1173 (583 anchored stand-alone and 590 plate). Dinc% scores were statistically significantly lower in the stand-alone anchored spacer compared to the plate-screw construct ( P ≤ .05). ANOVA showed no statistically significant difference in the comparisons of SQOL. On the other hand, NDI scores were statistically significantly lower in baseline of stand-alone anchored spacer and the plate-screw construct compared with both immediate postoperative and last follow-up visits ( P ≤ .05). </jats:p></jats:sec><jats:sec><jats:title>Conclusions:</jats:title><jats:p> Our study results revealed that the stand-alone anchored spacers were associated with less dysphagia in the immediate and last follow-up. </jats:p></jats:sec>

As a Neurosurgeon with fellowship training in Spine Surgery, I have dedicated my professional life to treating patients with spine disorders. These include spinal stenosis, spondylolisthesis, scoliosis, herniated discs and spine tumors. I incorporate minimally-invasive spine (MIS) techniques whenever appropriate to minimize pain and length of stay, yet not compromise on achieving the goals of surgery, which is ultimately to get you back to the quality of life you once enjoyed. I was drawn to medicine and neurosurgery for the unique ability to incorporate the latest in technology and neuroscience to making patients better. I will treat you and your loved ones with the same kind of care I would want my loved ones to be treated with. In addition to my clinical practice, I will be working with Duke Bioengineers and Neurobiologists on important basic and translational questions surrounding spinal cord injuries (SCI), which we hope to bring to clinical relevance.
