颈椎间盘置换术治疗颈椎病的短期疗效观察

目的:探讨颈椎间盘置换术治疗颈椎病的临床疗效。方法:观察2010年3月～2011年1月期间皖南医学院附属弋矶山医院脊柱外科采用颈椎间盘置换术治疗颈椎病患者20例;记录并比较术前、术后3个月及末次随访患者的颈椎JOA评分、椎间高度、颈椎活动度和脊柱功能单位活动度。结果:平均随访(18.9±7.23)个月。患者临床症状明显缓解。JOA评分、椎间高度术前与术后、末次随访差异有统计学意义(P<0.05)。颈椎活动度和脊柱功能单位活动度术后及末次随访数据与术前比较差异均无统计学意义(P>0.05)。结论:在严格把握手术适应证和禁忌症的情况下,颈椎间盘置换术可取得满意的临床疗效,同时可预防和减少邻近节段退变的发生,值得临床推广应用。

Short-term curative effects of cervical disc replacement for cervical spondylosis

Objective：To observe the curative effects of artificial disc for cervical disc replacement in treatment of cervical spondylosis. Methods： The curative effects were reviewed in 20 patients undergone artificial in- tervertebral disc replacement between March 2010 and January 2011, with regard to the JOA scoring, intervertebral height, motion range of the cervi- cal vertebra and functional spinal unit range of motion before surgery and three month after the procedure as well as the final follow-up. Results ： The follow-up lasted for （18.9 ＋ 7.23 ） months on average, and it suggested that all patients achieved significant clinical remission. JOA scoring, the intervertebral disc height observed pre-and post-operatively and at final follow-up were statistically different （ P 〈 0.05 ）, yet the motion range of cervical vertebra and functional spinal unit range of motion showed no sig- nificance difference after the procedure and at the final follow-up （ P 〉0. 05 ）. Conclusion ： In the event of the indications and contraindications being stringently controlled, artificial disc replacement for cervical spondy- losis may lead to better curative outcomes and simultaneously reducing de- generation of adjacent segments of the cervical spine, and is worthy of wi- der clinical application.
