Anterior cervical graft fusion alone or supplemented with an anterior cervical plate instrumentation may be used to treat the diseased cervical spine. An anterior cervical plate is intended to restore the mechanical integrity of the operated spine and decrease graft complications. An alternative method to single-level graft fusion is to use an interbody fusion device. The objective of this study was to compare the biomechanical stability of a single-level graft-plated cervical construct with an interbody cage device.

Abstract Purpose This study was to compare the clinical outcomes, radiographic parameters, and complications of anterior cervical discectomy and fusion (ACDF) with a Zero-profile implant (Zero-P) and traditional plate and cage. Methods There were 68 patients received ACDF of single level, 35 patients with Zero-profile implant (Zero-p group) and 33 patients with traditional plate and cage (Cage group), from C3–C7 during 2014 to 2016. Collecting and analyzing of clinical and radiological data were performed. Patients were followed-up at least 1 year after surgery. The operation time, blood loss, Japan Department of Orthopedics Association (JOA) score, pain Visual Analogue Score (VAS), Neck Disability Index (NDI) score and dysphagia score were recorded. Additionally, changes in cervical lordosis, fusion rate and adjacent segment degeneration were analyzed as well. Results For neurologic outcomes, the JOA, VAS and NDI were statistically equivalent between the two groups (P>0.05). For radiographic outcomes, there were no significant differences in the C2-7 Cobb angles, segmental Cobb angle and incidence of subsidence at the final follow-up (P>0.05). No degenerative changes was found in the Zero-p group, whereas 5 patients in the Cage group developed degeneration in adjacent segments (P<0.05). Also, the incidence of postoperative dysphagia is higher in Cage group than in Zero-p group at 3 months and 12 months (P<0.05). Conclusions Both Zero-profile implant and anterior cervical plate interbody fusion device were demonstrated to be effective and safe strategies in this study. Considering the lower incidences of dysphagia and degenerative changes, the Zero-profile implant is a good succedaneum.

Abstract Background Anterior cervical discectomy and fusion (ACDF) is a successful strategy to relieve the symptoms caused by cervical degenerative disease. Postoperative dysphagia is one complication of this kind of surgery.

Collecting and analyzing of clinical and radiological data were performed. Patients were followed-up at least 1 year after surgery. The operation time, blood loss, Japan Department of Orthopedics Association (JOA) score, pain Visual Analogue Score (VAS), Neck Disability Index (NDI) score and dysphagia score were recorded.

<p class="abstract"><strong>Background:</strong> Anterior cervical discectomy (ACD) was used for management of degenerative cervical disc disorders (DCDD) in previous days. Further research and developments in management of DCDD led to evolution of standard and widely used operative technique as anterior cervical discectomy and fusion (ACDF) by either anterior cervical plate (ACDF-ACP) with bone grafting or stand-alone cage (ACDF-SAC). There is less data available in literature regarding when and where to use ACDF-ACP and ACDF-SAC.</p><p class="abstract"><strong>Methods:</strong> The study was conducted on 20 patients operated in Government Medical College and Hospital and Pacific Hospital and Research Centre, Aurangabad from June 2018 to March 2020. These patients divided into group A - 10 patients, operated by ACDF-SAC which are further divided as group Aa - 6 patients - operated for single level ACDF-SAC and group Ab - 4 patients - operated for two level ACDF-SAC, group B - 10 patients, operated by ACDF-ACP which are further divided as group Ba - 5 patients - operated for single level ACDF-ACP and group Bb - 5 patients - operated for two level ACDF-ACP. Patients evaluated preoperatively and postoperatively using X-ray cervical spine anteroposterior (AP) and lateral views, MRI cervical spine, visual analogue scale (VAS) for pain, Robinson’s criteria and Cobb’s angle.<strong></strong></p><p class="abstract"><strong>Results:</strong> In our study we found, ACDF-SAC has small incision size, less intraoperative time, easy to carry out for surgeons, less intraoperative complications and better clinical outcome as compared to ACDF-ACP. Whereas only radiological results were better in ACDF-ACP than ACDF-SAC.</p><p class="abstract"><strong>Conclusions:</strong> ACDF-SAC is superior to ACDF-ACP for appropriately selected patients and in well experienced hands.</p>

Object Although smoking has been shown to negatively affect fusion rates in patients undergoing multilevel fusions of the cervical and lumbar spine, the effect of smoking on fusion rates in patients undergoing single-level anterior cervical discectomy and fusion (ACDF) with allograft and plate fixation has yet to be thoroughly investigated. The objective of the present study was to address the effect of smoking on fusion rates in patients undergoing a 1-level ACDF with allograft and a locked anterior cervical plate. Methods This study is composed of patients from the control groups of 5 separate studies evaluating the use of an anterior cervical disc replacement to treat cervical radiculopathy. For each of the 5 studies the control group consisted of patients who underwent a 1-level ACDF with allograft and a locked cervical plate. The authors of the present study reviewed data obtained in a total of 573 patients; 156 patients were smokers and 417 were nonsmokers. A minimum follow-up period of 24 months was required for inclusion in this study. Fusion status was assessed by independent observers using lateral, neutral, and flexion/extension radiographs. Results An overall fusion rate of 91.4% was achieved in all 573 patients. A solid fusion was shown in 382 patients (91.6%) who were nonsmokers. Among patients who were smokers, 142 (91.0%) had radiographic evidence of a solid fusion. A 2-tailed Fisher exact test revealed a p value of 0.867, indicating no difference in the union rates between smokers and nonsmokers. Conclusions The authors found no statistically significant difference in fusion status between smokers and nonsmokers who underwent a single-level ACDF with allograft and a locked anterior cervical plate. Although the authors do not promote tobacco use, it appears that the use of allograft with a locked cervical plate in single-level ACDF among smokers produces similar fusion rates as it does in their nonsmoking counterparts.

Abstract Cervical spondylosis is the most common degenerative disorder affecting the cervical spine and is often treated surgically to prevent further neurological deterioration. However, clinical experience has shown that anterior cervical plating does not prevent construct failure in multi-level cervical corpectomy (Vaccaro et al., 1998). We have previously shown that anterior cervical plating reverses the load transfer through multi-level strut-grafts and may promote pistoning of these grafts (DiAngelo et al., 2000). The design of the anterior cervical plate (ACP) may contribute to this phenomenon. The purpose of this study was to compare the graft loading mechanics of two different anterior cervical plating systems; one with a constrained plate-screw interface versus another with a semi-constrained, translational plate-screw interface.
