【摘要】：[目的]评价前路减压Zero-p椎间融合器治疗颈椎病临床和影像学结果。[方法]回顾性分析2010年1月~2013年1月接受颈椎前路椎间盘切除融合术(anterior cervical discectomy and fusion,ACDF)联合Zero-p椎间融合器固定治疗颈椎病患者相关资料。临床功能评估采用颈椎功能障碍指数(neck disability index,NDI)、疼痛视觉模拟评分(visual analogue scale,VAS),影像学评估采用颈椎正侧位X线片,通过Cobb角测量方法,测量病变节段上下椎体Cobb角,测量C_(3~7)椎体颈前软组织厚度,并于术后2年评估融合情况,吞咽困难等并发症也被观察。[结果]共纳入45例患者(50个节段),27例男性和18例女性,平均年龄(45.64±6.28)岁。所有患者至少随访24个月,平均随访时间为(41.11±7.82)个月。患者术后NDI、VAS评分均较术前有明显改善。影像学上94%的置入物融合。最终随访时颈椎前凸保持良好。术后颈前软组织厚度较术前显著增加,从平均(7.6±1.9)mm增至(15.2±2.9)mm,最终随访时(9.9±1.9)mm。按吞咽困难Bazaz分级,术后吞咽困难发生率44.4%,然而在最终的随访时仍有6.6%的患者具有轻、中度吞咽困难。在术后即刻和最终随访时颈前软组织厚度和吞咽困难分级Pearson相关性分析表明二者呈显著正相关。1例患者术后出现持续性的左上肢疼痛伴左三角肌肌力减弱,1例患者发生声音嘶哑,随访3个月后完全恢复。[结论]颈前椎间盘切除融合术联合Zero-p椎间融合器固定治疗颈椎病可获得较好的临床和影像学结果,术后吞咽困难发生与颈前软组织厚度呈显著正相关。
[Abstract]:Objective to evaluate the clinical and imaging results of anterior decompression Zero-p interbody fusion cage in the treatment of cervical spondylosis. [methods] from January 2010 to January 2013, the data of patients with cervical spondylosis treated with anterior cervical discectomy and fusion (anterior cervical discectomy and fusion,ACDF) combined with Zero-p interbody fusion cage were analyzed retrospectively. The clinical function was evaluated by cervical dysfunction index (neck disability index,NDI) and pain visual analog score (visual analogue scale,VAS). The imaging evaluation was performed with anterior and lateral cervical X-ray films, and the angle of cervical vertebrae was measured by Cobb angle measurement. The Cobb angle of the upper and lower vertebrae and the thickness of the anterior cervical soft tissue of the C _ (3 鈮，
