摘要:

背景:颈椎前路钢板置入内固定被认为是颈椎前路多节段椎间盘切除和融合的标准治疗,但是,颈前路植入钢板有着很多金属植入物相关并发症的风险。
目的:分析和比较使用颈椎桥形连接融合器和Cage椎间融合器+颈椎前路钢板置入内固定进行颈椎前路2节段以上椎间融合的有效性。
方法:纳入54例2节段以上颈椎间盘突出接受颈椎前路减压和融合治疗的患者,分别使用颈椎桥形连接融合器进行颈椎前路椎间融合(n=30)和Cage椎间融合器与颈椎前路钢板固定系统进行椎间融合(n=24)。使用日本骨科学会(JOA)量表系统评价临床结果,椎间融合后3,6个月依据X射线检查评价颈椎前凸角、椎体间高度和颈椎融合状态。
结果与结论:对桥形连接融合器和Cage椎间融合器组的平均随访时间为6个月。两组患者均获得骨性融合,平均愈合时间为5.5个月。桥形连接融合器组平均JOA评分由治疗前(7.4±0.4)分,提高到治疗后3个月(14.3±0.5)分,治疗后6个月(14.5±0.8)分,Cage椎间融合器组平均JOA评分由治疗前(7.6±0.7) 分,提高到治疗后3个月(13.9±0.4)分,治疗后6个月(14.0±0.6)分,且有显著性差异。治疗后两组的颈椎前凸角和椎间隙高度均较治疗前有显著性改善。说明该植入体植入后能有效恢复颈椎的生理曲度,避免出现螺钉钢板固定并发症,疗效确切。

Abstract:

BACKGROUND: Anterior cervical spine plate fixation is believed to be the standard method for the treatment of cervical anterior segmental discectomy and fusion, however, anterior cervical plate implants has a lot of risk related to metal implants complications.
OBJECTIVE: To analyze and compare the effectiveness of the application of double-way connection intervertebral fusion device and Cage intervertebral fusion device+anterior cervical plate fixation for anterior above two-level cervical interbody fusion.
METHODS: Fifty-four patients with above two-level cervical intervertebral disc herination were treated with anterior cervical decompression and fusion. These patients were treated with anterior cervical interbody fusion using double-way connection intervertebral fusion device (n=30) and Cage intervertebral fusion device and anterior plate fixation system (n=24). The clinical results were evaluated with Japanese Orthopedic Association scale scores, and the cervical curvature, intervertebral height and cervical fusion state were tested with X-ray film at 3 and 6 months after interbody fusion.  
RESULTS AND CONCLUSION: All patients were followed-up for 6 months. The patients in two groups got osseous fusion, and the average fusion time was 5.5 months. Average Japanese Orthopedic Association scale score of double-way connection intervertebral fusion device group was increased from (7.4±0.4) preoperatively to (14.3±0.5) at 3 months and (14.5±0.8) at 6 months postoperatively; and the average Japanese Orthopedic Association scale score of Cage intervertebral fusion device group was increased from (7.6±0.7) preoperatively to (13.9±0.4) at 3 months and (14.0±0.6) at 6 months postoperatively, and the differences were significant. The spinal curvature and intervertebral height were significantly improved after treatment. This procedure can effectively restore cervical lordosis, obviate the complications related to graft harvest and screw-plate fixation, and lead to satisfactory outcomes.
