摘要:

背景:近年来,内固定系统和技术不断改进,行颈椎前路减压植骨的同时行前路钢板内固定已被大多数学者所接受,但与之有关的并发症也不断出现。鉴于此,零切迹椎间植骨融合钢板(Zero-P)被批准应用于临床治疗颈椎退行性疾病。
目的:探讨Zero-P在颈椎前路减压植骨融合内固定中的早期应用效果。
方法:2014年2至12月采用零切迹颈前路融合钢板对22例颈椎病患者行颈椎前路减压植骨融合内固定治疗。C3-4,C4-5,C5-6分别置入Zero-P为1,3,18枚。治疗后应用目测类比评分和JOA评分来评价疼痛及神经功能改善情况,并拍摄颈椎正侧位及过伸过屈侧位线片,根据测量治疗后颈椎侧位X射线片上钢板头、尾侧相邻椎间隙与椎体高度的比值(R)及相邻节段骨质增生情况来判断相邻节段退变情况。根据治疗后伸屈侧位X射线片观察手术间隙有无异常活动。
结果与结论:22例患者随访10-28个月,2例患者分别于治疗后第4天和第5天出现吞咽困难(均为轻度),均于治疗后2周内症状消失。所有患者治疗后的目测类比评分均低于治疗前(P < 0.05),JOA评分均高于治疗前(P < 0.05),颈椎Cobb角均大于治疗前(P < 0.05),治疗后不同时间点的目测类比评分、JOA 评分和颈椎Cobb角差异均无显著性意义(P > 0.05)。钢板头侧相邻椎间隙中3例(均为1级)椎体出现骨质增生,尾侧有1例(1级)出现;头、尾两侧骨质增生差异无显著性意义(P > 0.05)。头、尾侧R值治疗前后差异无显著性意义(P > 0.05),随访期间手术间隙无异常活动, 内置物无移位。提示Zero-P修复单节段椎间盘病变效果显著,能有效改善颈椎曲度,建立良好的颈椎稳定性,治疗后吞咽困难发生率低,早期不增加相邻节段的退变。

Abstract:

BACKGROUND: In recent years, with the continuously improving of the fixation systems and technology, conducting anterior cervical decompression bone graft accompanying with anterior plate fixation have been accepted by most scholars, however, the complications related to this also appeared constantly. In view of this, the zero notch interbody fusion plate (Zero-P) has been approved for the clinical treatment of cervical degenerative disease.
OBJECTIVE: To discuss the early application effect of Zero-p on anterior cervical decompression and fusion.
METHODS: The study enrolled 22 patients who underwent anterior cervical decompression and fusion with Zero-P between February and December 2014. The number of Zero-P implanted in the C3-4, C4-5, C5-6 was 1, 3  and 18 respectively. Pain and neurological improvement were evaluated using Visual Analog Scales score and Japanese Orthopaedic Association (JOA) score for all the patients after operation. The X-ray plain of lateral and flexion-extension lateral of cervical vertebra were shot. The degradation degree was judged based on the measurement results from the cervical lateral X-ray films about the ratio of cephalad and caudal adjacent intervertebral space to vertebral body height, and adjacent segments osteoarthritis situation. The abnormal activity at the surgical spaces was observed by the extension and flexion lateral X-ray plain. 
RESULTS AND CONCLUSION: Twenty-two patients obtained follow up for 10-28 months. 2 patients had dysphagia on the fourth day and the fifth day after operation (extremely mild). The symptom disappeared within 2 weeks after treatment. The Visual Analog Scales score was significantly lower compared with preoperation (P < 0.05), the JOA score was significantly higher than that before operation (P < 0.05) , the cervical Cobb angle was significantly higher than that before operation (P < 0.05). There were no significant differences statistically in comparison of the Visual Analog Scales score, JOA score and cervical Cobb angle at different time points after operation (P > 0.05). In cephalad adjacent intervertebral space, 3 cases had developed hyperosteogeny (first level). In caudal adjacent intervertebral space, 1 had developed hyperosteogeny (first level). There was no significant difference in the hyperosteogeny between cephalad adjacent intervertebral space and caudal adjacent intervertebral space (P > 0.05). There was no significant difference in the R value in cephalad adjacent intervertebral space and caudal adjacent intervertebral space between preoperation and postoperation (P > 0.05). During the follow-up, no abnormal activity at the surgical spaces and implant displacement was observed. These results suggest that using Zero-p in the treatment of monosegmental disc disease has significant effect, can effectively improve the cervical curvature and establish good cervical stability. The incidence of postoperative dysphagia is low. The degeneration of adjacent segments after treatment was not increased in early stage.
