摘要:


文题释义:

融合器下沉高度:术后2 d融合节段头侧椎体上终板中点与尾侧椎下终板中点之间的距离减去末次随访融合节段高度,若下沉高度> 2 mm,定义为阳性。
颈椎病:颈椎椎间盘组织退行性改变及其继发性病理改变累及其周围组织结构,如神经根、脊髓、椎动脉、交感神经、食管等,并出现相应的临床表现,是导致颈肩臂痛的最常见原因之一,发病率为3.8%-17.6%。

背景:目前研究报道椎间融合器材料是影响颈椎病患者术后疗效的因素之一,但关于相同材料不同几何形状对颈椎病患者术后疗效的报道较少。
目的:观察纳米羟基磷灰石/聚酰胺66椎间融合器形状对颈椎前路椎间盘切除融合疗效的影响。
方法:回顾性分析2016年1月至2020年6月于西南医科大学附属医院行单节段颈椎前路椎间盘切除融合手术患者的临床资料,共122例,根据术中使用纳米羟基磷灰石/聚酰胺66椎间融合器形状不同分为柱形组(n=60)、马蹄形组(n=62)。对比两组患者手术前后的目测类比评分、颈椎功能障碍指数、融合节段高度、C2-7角、融合节段矢状成角及椎间融合情况。

结果与结论:①与术前比较,两组术后2 d、1年及末次随访的目测类比评分降低(P < 0.05),术后6个月及末次随访的颈椎功能障碍指数影响降低(P < 0.05);两组间手术前后的目测类比评分、颈椎功能障碍指数比较差异均无显著性意义(P > 0.05);②马蹄形组术后6,12个月的融合率高于柱形组(P < 0.05),术后6,12个月的改良Brantigan评分均低于柱形组(P < 0.05);③末次随访时,马蹄形组融合器下沉高度低于柱形组(P < 0.05),两组融合器沉降率比较差异无显著性意义(P > 0.05);④两组间手术前后的C2-7角、融合节段矢状成角、融合节段高度、融合节段矢状成角比较差异均无显著性意义(P > 0.05);⑤结果显示,在单节段颈椎前路椎间盘切除融合中,使用马蹄形及柱形纳米羟基磷灰石/聚酰胺66椎间融合器均可获得良好的疗效,其中应用马蹄形纳米羟基磷灰石/聚酰胺66椎间融合器可提高早期融合率并减少椎间隙下沉。

Abstract: BACKGROUND: Current studies have reported that interbody fusion materials are one of the factors affecting the postoperative efficacy of patients with cervical spondylosis, but there are few reports on the postoperative efficacy of the same materials with different geometric shapes in patients with cervical spondylosis. 
OBJECTIVE: To observe the effect of nano-hydroxyapatite/polyamide-66 intervertebral fusion cage shape on the efficacy of anterior cervical discectomy and fusion. 
METHODS: Clinical data of 122 patients with single-segment cervical spondylosis who were admitted to the Affiliated Hospital of Southwest Medical University from January 2016 to June 2020 were retrospectively analyzed. They were divided into a columnar group (n=60) and a horseshoe group (n=62) according to the shape of nano-hydroxyapatite/polyamide-66 intervertebral fusion (cage). The visual analog scale score, neck disability index, fusion segmental height, C2-7 angle, segmental sagittal alignment, and intervertebral fusion were compared between the two groups before and after the operation. 
RESULTS AND CONCLUSION: (1) Compared with that before operation, the visual analog scale scores of the two groups at 2 days, 1 year and the last follow-up decreased (P < 0.05), and the influence of neck disability index at 6 months and the last follow-up decreased (P < 0.05). There was no significant difference between the two groups in visual analog scale score and neck disability index before and after surgery (P > 0.05). (2) The fusion rate of the horseshoe group at 6 and 12 months after surgery was significantly higher than that of the columnar group (P < 0.05). The modified Brantigan score of the horseshoe group at 6 and 12 months after operation was lower than that of the columnar group (P < 0.05). (3) The extent of cage subsidence in patients in the horseshoe group was lower than that in the columnar group (P < 0.05). There were no significant differences in the extent of cage subsidence between the two groups (P > 0.05). (4) There were no significant differences in C2-7 angle, segmental sagittal alignment, and fusion segmental height between the two groups before and after surgery (P > 0.05). (5) The results show that the horseshoe and columnar nano-hydroxyapatite/polyamide-66 intervertebral fusion cage can obtain good efficacy in the single-segment anterior cervical discectomy and fusion, but the horseshoe nano-hydroxyapatite/polyamide-66 intervertebral fusion cage can improve the early fusion rate and reduce the subsidence of the intervertebral space.
