文题释义:
Zero-P系统:是采用颈前路零切迹设计理念的一种新型融合器,稳固性更高,它将钛板与融合器巧妙的结合,钛板可以一起代替切除的椎间盘,椎体间隙的前缘没有凸起物,对椎体前方的组织无阻碍。术中无需切除相邻椎体的前纵韧带,操作相对简单,可明显减少手术时间。
颈椎间盘突出症:其发病与颈部损伤和椎间盘发生退行性变有关,一般认为是在椎间盘尚无明显退行性改变的基础时突然发生的,是因受到一定的外力作用而使纤维环破裂,引起髓核后突,突出的髓核直接引起颈髓或神经根受压。
 
摘要
背景:颈前路椎间盘切除减压植骨融合治疗颈椎间盘突出症的效果显著,但有颈椎不稳、融合率低等缺点,钛板融合器可以弥补这些缺点,但仍有一些常见并发症发生。一种新型的同时具有支持和固定椎体的一体式颈前路零切迹(Zero-P)椎间融合器在临床广泛应用。
目的:对比颈前路零切迹椎间融合内固定与钛板融合器内固定治疗颈椎间盘突出症的临床效果。
方法:回顾性分析2016年1月至2017年6月在佛山市禅城区中心医院接受治疗的42例单节段颈椎病患者的临床资料,根据手术方式分为2组,其中颈前路零切迹椎间融合内固定治疗组(Zero-P组)21例,颈前路钛板融合器内固定治疗组(钛板组)21例。比较2组患者的手术时间、术中出血量、日本骨科学会评分及其改善率、吞咽困难程度、Cobb 角、融合节段椎体间高度及其增加率。
结果与结论:①Zero-P组术中出血量与钛板组相比差异无显著性意义(P > 0.05),但Zero-P组手术时间明显短于钛板组(P < 0.05);②术后3,6,18个月时2组的JOA评分均较术前显著增加(P < 0.05),但在相同随访时间2组的日本骨科学会评分及其改善率相比差异无显著性意义(P > 0.05);③术后6个月钛板组有2例(10%)发生轻度吞咽困难,而Zero-P组吞咽困难症状消失;术后18个月钛板组仍有1例(5%)发生轻度吞咽困难;④Zero-P组Cobb 角术后3,6,18个月与钛板组相比差异有显著性意义(P < 0.05);⑤2组椎体间高度增加率术后3 个月相比差异无显著性意义(P > 0.05),而术后6,18个月Zero-P组椎体间高度增加率显著高于钛板组(P < 0.05);⑥提示对颈椎间盘突出症患者实施颈前路零切迹椎间融合内固定与钛板融合器内固定治疗均可以取得良好的效果;但零切迹椎间融合内固定更有利于维持颈椎曲度及椎体间高度,并降低术后吞咽难的发生率,因此更具优势。

Abstract:

BACKGROUND: Anterior cervical discectomy and decompression, and fusion for treating cervical disc herniation have significant effects, but there are shortcomings such as cervical instability and low fusion rate. Titanium plate with cage interbody fixation and fusion system can make up for these shortcomings, but there are still some common complications. A new Zero-P interbody fixation and fusion system with support and fixation function is widely used in clinical practice.

OBJECTIVE: To compare the clinical effect of a new Zero-P interbody fixation and fusion system and titanium plate with cage interbody fixation and fusion system for treating cervical disc herniation.
METHODS: Clinical data of 42 patients with single-segment cervical spondylosis admitted at Foshan Chancheng Central Hospital from January 2016 to June 2017 were analyzed retrospectively. According to the surgical method, 21 cases were treated with Zero-P interbody fixation and fusion system (Zero-P group) and 21 cases with titanium plate with cage interbody fixation and fusion system (titanium plate group). The operation time, intraoperative blood loss, Japanese Orthopaedic Association score and improvement rate, dysphagia, Cobb angle, and height and increase rate of the fused segment were compared between two groups.
RESULTS AND CONCLUSION: (1) There was no significant difference in the intraoperative blood loss between two groups (P > 0.05), and the operation time in the Zero-P group was significantly shorter than that in the titanium plate group (P < 0.05). (2) The Japanese Orthopaedic Association scores in the two groups were significantly increased at 3, 6 and 18 months postoperatively (P < 0.05), and no significant difference was found in the scores and score improvement rate between two groups at the same follow-up time (P > 0.05). (3) Two patients (10%) in the titanium plate group developed mild dysphagia at 6 months after surgery, while the symptoms of dysphagia in the Zero-P group disappeared. There was still one case (5%) of mild dysphagia in the titanium plate group at postoperative 18 months. (4) The Cobb angle in the Zero-P group was significantly different from the titanium plate group at 3, 6 and 18 months postoperatively (P < 0.05). (5) There was no significant difference in the rate of height increase between two groups at 3 months postoperatively (P > 0.05). There was a significant difference in the rate of intervertebral height between two groups postoperative at postoperative 6 and 18 months (P < 0.05). (6) To conclude, Zero-P interbody fixation and fusion system and titanium plate with cage interbody fixation and fusion system for treating cervical disc herniation both can achieve good results. However, Zero-P interbody fixation and fusion system is more conducive to maintaining cervical curvature and intervertebral height, and reducing the incidence of postoperative dysphagia.
