This study analyzed clinical and radiological outcomes of a zero-profile anchored spacer (Zero-P) and conventional cage-plate (CCP) for single level anterior cervical discectomy and fusion (ACDF) to compare the incidence and difference of postoperative dysphagia with both devices.
We retrospectively reviewed our experiences of single level ACDF with the CCP and Zero-P. From January 2011 to December 2013, 48 patients who had single level herniated intervertebral disc were operated on using ACDF, with CCP in 27 patients and Zero-P in 21 patients. Patients who received more than double-level ACDF or combined circumferential fusion were excluded. Age, operation time, estimated blood loss (EBL), pre-operative modified Japanese Orthopaedic Association (mJOA) scores, post-operative mJOA scores, achieved mJOA scores and recovery rate of mJOA scores were assessed. Prevertebral soft tissue thickness and postoperative dysphagia were analyzed on the day of surgery, and 2 weeks and 6 months postoperatively.
The Zero-P group showed same or favorable clinical and radiological outcomes compared with the CCP group. Postoperative dysphagia was significantly low in the Zero-P group.
Application of Zero-P may achieve favorable outcomes and reduce postoperative dysphagia in single level ACDF.
本研究分析了零轮廓锚定椎间融合器（Zero-P）与传统椎间融合器钢板（CCP）用于单节段颈椎前路椎间盘切除融合术（ACDF）的临床和影像学结果，以比较两种器械术后吞咽困难的发生率及差异。
我们回顾性分析了采用CCP和Zero-P进行单节段ACDF的经验。2011年1月至2013年12月，48例单节段椎间盘突出症患者接受了ACDF手术，其中27例使用CCP，21例使用Zero-P。排除接受多节段ACDF或联合环形融合术的患者。评估患者的年龄、手术时间、估计失血量（EBL）、术前改良日本骨科协会（mJOA）评分、术后mJOA评分、获得的mJOA评分及mJOA评分恢复率。在手术当天、术后2周和6个月分析椎体前软组织厚度及术后吞咽困难情况。
与CCP组相比，Zero-P组显示出相同或更好的临床和影像学结果。Zero-P组术后吞咽困难明显较少。
在单节段ACDF中应用Zero-P可能取得良好效果并减少术后吞咽困难。
