Abstract

目的　探讨单嵌片自稳型颈椎融合器在颈椎前路减压融合术中的应用，报告5年随访疗效。方法　选取47例因脊髓型或神经根型颈椎病行颈椎前路减压+单嵌片自稳型颈椎融合器置入术患者。侧位X线片观察椎间高度、颈椎前凸角及植骨融合率；术前及术后进行JOA评分，观察神经功能恢复情况；VAS评分评价患者颈部或肢体疼痛；SF-36健康调查评分观察临床疗效。结果　术后6个月67个融合节段均获骨性融合。椎间隙高度术前为（4.47±0.86）mm，末次随访为（7.41±0.72）mm。颈椎前凸角术前为（0.7±4.1）°，末次随访为（5.9±3.6）°。随访56~96个月，所有患者未出现严重手术并发症，神经功能有明显恢复。JOA评分由术前（9.15 ±0.22）分增至末次随访（14.89±0.16）分，VAS评分由术前（5.24±1.44）分减至末次随访（0.35±0.49）分。JOA及VAS评分术前较术后各次随访具有统计学差异（P<0.05)，但术后各次随访之间无统计学差异（P>0.05）。SF-36健康调查评分6个维度，术前及术后评分均具有统计学差异（P<0.05）。结论　单嵌片自稳型颈椎融合器能使融合节段获得即刻稳定性，有效恢复和维持椎间隙高度，植骨融合率高，中远期疗效好，适用于多种需前路减压的颈椎退变性疾病。
